Device for deflecting a material web

[0001] The invention relates to a device for deflection in accordance with the preamble of claim 1 or 11.

[0002] A device for shifting narrow paper webs in the form of partial paper webs is known from DE 38 16 900 A1.

[0003] DE-AS 17 61 899 shows turning bars which are staggered in height.

[0004] U.S. Pat. No. 3,734,487 discloses two turning bars arranged in a triangle, from which a web of material can be conducted to a registration roller.

[0005] EP 0 784 590 B1 discloses a turning arrangement, a guide roller and the turning bars of which have different diameters. The turning bars, which are arranged at 90° in respect each other are of equal diameter.

[0006] The object of the invention is based on creating a device for deflecting a web of material.

[0007] In accordance with the invention, this object is attained by means of the characteristics of claims 1 or 11.

[0008] The advantages which can be achieved by means of the invention reside primarily in that a guidance arrangement can be created which—viewed in the running direction of the paper web—permits a shorter construction than guidance arrangements up to now, and with at least the same number of partial paper web shifts, which can serve downstream-connected devices with several longitudinal folding devices and/or transverse cutting devices. It is moreover possible to achieve a lower structural height.

[0009] The number of deflection devices can be reduced. Shorter paper travel is also achieved. The linear register (cutting register) remains within the permissible tolerance range during breaking, and of course also acceleration, even at the highest web running speeds, so that the amount of waste is clearly reduced. This is the result of the fact that the linear registration rollers are only laid out to the maximum width of the partial paper webs, and not to the maximally possible paper web width. Because of this the centrifugal masses which must be accelerated or braked become considerably smaller. It is possible to bring the turning bars in each horizontal plane—it can be one, two or even more—individually or together brought preselectable positions by means of a remotely controllable drive mechanism, which enormously shortens the required amount of time for production changes. Each one of these guidance arrangements can be produced as a whole with all electro-pneumatic and mechanical installations as a stackable modular unit by itself. Depending on the number of paper webs, or partial paper webs, to be processed, the modular units are then “stacked on top of each other” and are connected with each other to form a paper guidance arrangement.

[0010] An exemplary embodiment of the invention is represented in the drawings and will be explained in greater detail in what follows.

[0011] Shown are in:

[0019]
FIG. 8, a “deflection device module” in accordance with FIG. 1, represented by way of example with two paper paths of two partial paper webs, with half a partial paper web of “whole web width” entering from the left, and half a partial paper web of “whole web width” entering from the right, which has been cut into two partial paper webs of “one-quarter web width”, in a perspective representation.

[0020] In principle, a “left partial paper web entry” and a “right partial paper web entry” into a folding apparatus 50 with at least two upstream-connected longitudinal folding devices is possible. In actual use, a decision is made prior to planning the layout of the web-fed rotary printing press whether it is to be equipped with a “left partial paper web entry or a right partial paper web entry”. With a “left entry”, a left partial paper web 04 runs—viewed in the paper running direction L—directly, i.e. “not turned”, into a left longitudinal folding apparatus, for example. With a “right entry”, a right partial paper web 03 runs—viewed in the paper running direction L (production direction)—directly, i.e. “not turned”, directly or via a guide roller 73 of a roller housing frame 20 into a folding apparatus 50 with one or several longitudinal folding devices. It is also possible to provide more than two longitudinal folding devices. In this case the running direction L is the running direction in which one paper web 02, or partial paper webs 03, 04, runs/run up on a guide roller 11 (production direction). Left transverse running directions QL and right transverse running directions QR are web/partial web running directions which refer to the running direction L and are directed transversely to the left (QL), or transversely to the right (QR).

[0021] Partial paper webs 03, 04 within the meaning of this application are understood to be not only “narrow” paper webs 03, 04, 03L, 03R, 04L, 04R, which can be produced by longitudinal cutting from a whole-width or half-width paper web 02. They can also be “narrow” paper webs 03, 04, which are fed from “narrow”, so-called quarter-width or eighth-width paper rolls, or also “narrow” paper webs 03, 04, which originate from other printing presses which are upstream-connected simultaneously with the running production of this paper web guidance device 01, or which are supplied, already preprinted, as a web from a storage device.

[0022] For example, as represented in FIGS. 1, 2 and 3—and viewed in the paper running direction L—, the rollers 30, 11, 35 are rotatably seated in a left lateral frame 06 and a right lateral frame 07 of the paper web guidance device 01. Both lateral frames 06, 07 are arranged parallel next to each other and spaced apart.

[0023] A left transverse frame 08, or a right transverse frame 09 are attached at right angles to and on the lateral frames 06, 07. They are aligned with each other and they laterally past the left lateral frame 07 (FIG. 1), or the right lateral frame 08 for a sufficient length so that—viewed in the transverse running direction QL and QR—there are sufficiently wide movement possibilities to the left and right for intended deflection devices 13, 14 and/or. The ends of the transverse frames 08, 09 terminate in a left bearing block 57, or right bearing block 58, they are parallel in respect to each other. The bearing blocks 57, 58 are of the same height and width as the transverse frames 08, 09 and project in the web running direction L. An upper guide rod 59 and a lower guide rod 61 are each attached with their two ends, fixed against relative rotation, in the transverse frames 57, 58. The guide rods 59, 61 are arranged horizontally and vertically above each other at the least possible distance b from each other, for example 8 to 25 cm (depending on the diameters of the deflection devices 13, 14, 29, arranged on top of each other, and the laterally arranged registration roller 16, and at the required horizontal distance from each other).

[0024] A paper web 02, for example without being longitudinally cut—because it came from below—coming from a print unit, not represented, which is part of the paper web guidance device 01, or from a print unit which produces in a parallel operation, of another web-fed rotary printing press, or from a preprinted rolled up paper roll, directly reaches a first driven or non-driven guide roller 11 or deflection roller. It is rotatably seated in lateral frames 06, 07. The guide roller 11 can be embodied as a counter-cutting roller, on which one or several driven longitudinal devices 12 are arranged so they can be placed against it or moved away from it. But it can also be designed as a driven traction roller. For driving the guide roller 11, a drive mechanism 44, for example an electric or pneumatic motor with an integrated angle of rotation transducer for detecting the actual number of revolutions and/or the actual angle of rotation 45, is flanged on the lateral frame 07, for example. When using the guide roller 11 as a traction roller, the motor 44 and the angle of rotation transducer 45 and a reference variable transducer, not represented, for setting the desired traction force on the paper web 02 is a control device provided, to which these are connected.

[0025] If the paper web 02 enters into the paper web guidance device 0l coming from above, a first additional deflection roller 30 and a second additional deflection roller 35 are rotatably seated, spaced apart from each other horizontally, in the lateral frames 06, 07. In this case the axes of rotation of the deflection rollers 30 and 35 lie—viewed in the paper web running direction L—to the left and right of and at a sufficient distance from the guide roller 11 on the same horizontal plane. Their axes of rotation preferably lie lower than that of the axis of rotation of the guide roller 11.

[0026] The rollers 30, 35 merely have the object of deflecting the incoming paper web 02, or so-called partial paper webs 03, 04, for example so-called “half-width” (03, 04), or so-called “quarter-width” partial paper webs (03L, 03R, 04L, 04R) in such a way that they run up correctly on the guide roller 11.

[0027] The paper web 02, or the partial paper webs 03, 04 are laterally aligned by means of an upstream-located lateral registration device, not represented. By means of this it is achieved that the not longitudinally cut paper web 02, or several partial paper webs, comes/come to lie within a left web path running border 55 and a right web path running border 56 of a web running path 54, whose position in the axial direction of the guide roller 11 can be preset. The web running path 54 has a maximum width b54, which is respectively wider than the maximally permissible paper web width b02, or the sum of all partial paper web widths of the partial paper webs 03, 04, 03L, 03R, 04L, 04R which can enter simultaneously into the paper web guidance device 01, depending on which is greater.

[0028] A device for displacement 22 with an associated registration roller 18 is attached to the “left entry”, as well as to the “right entry”, for example on the outside of the left bearing block 57 of the left transverse frame 08. The device for displacement 22 has a guide device 21 with a movable left carriage 19, on which the registration roller 18 is fastened, for example cantilevered, i.e. fastened only with one end, on a carriage 19. Its other end is free. The registration roller is respectively displaceable by means of the carriage 19 along the partial paper web running direction QL and QR of the partial paper web (03 or 04), which is running up on it (FIG. 1). For this purpose the device for displacement 22 has a drive mechanism 36 supported on it, with an integrated angle of rotation transducer 41. The device 22 has, for example, a motor drive 36, 41 with a gear for creating a linear movement. A positionally accurate displacement and fixation in place of the registration roller 18 is possible by means of it. Such a gear could be, for example, a worm gear with a traction spindle.

[0029] Viewed in the paper running direction L, a horizontal first (right) 45° deflection device 13, for example in the form of a turning bar 13, and to the left of it a horizontal second (left) 45° deflection device 14, for example in the form of a turning bar 14, are provided, spaced apart from the guide roller 11. Their ends 26, 27 remote from the guide roller 11 are rigidly fastened, for example on a common fastening carriage 16 (or two separate, separately driveable fastening carriages).

[0030] The 45° deflection devices 13, 14 can be displaced and fixed in place, for example by means of the common fastening carriage 16, transversely to the running direction L into the left transverse running direction QL and the right transverse running direction QR. The deflection devices 13, 14 can be displaced into the left transverse running direction QL and the right transverse running direction QR. The displacement of the right deflection device 13 is designed in such a way that its entire length can be displaced along at least the entire width of the provided running path of the whole-width paper web 02 (M1.02, M2.02, M3.02, M4.02, M5.02, etc.) and, further than that, can be moved toward the right completely out of the running path of the “whole-width” paper web 02, or out of the running path of the right “half-width” partial paper web 04.

[0031] The displacement of the left deflection device 14 is designed in such a way that its entire length can be displaced along at least the entire width of the provided running path of the whole-width paper web 02 (M1.02, M2.02, M3.02, M4.02, M5.02, etc.) and, further than that, can be moved toward the left completely out of the running path of the “whole-width” paper web 02, or out of the running path of the right “half-width” partial paper web 04. The movements of the two deflection devices 13, 14 take part together or individually in the same direction.

[0032] The (guide or) fastening carriage 16 can be displaced interlockingly along a straight guide device 52 (for example a dovetail guidance device), which can be a component of a cross arm 69, by means of a motor drive 33 with a gear, and is arranged to be fixed in place. The cross arm 69, and therefore the straight guide device 52, extends horizontally between a left short lateral frame 23 and a right short lateral frame 37 and is fastened on the insides of the latter.

[0033] A motor drive 34 supported on the transverse frame 09 (or on one of the short lateral frames) could be provided as the drive mechanism for the (every) carriage 16, for example an electric servo motor 34 with an angle of rotation transducer 39 flanged to it. The latter is respectively used for determining the actual value of the position of the respective carriage, on which one or both of the deflection devices 13, 14 are fastened. Furthermore, an electronic control device with an arrangement for presetting a position reference variable, a device for performing the comparison of the reference variable with the actual value, and an actuating device, not represented, for generating a manipulated variable to be fed to the drive 34, are provided per carriage. By means of this an accurate, and also presettable, positioning of the deflection devices 13, 14 is possible.

[0034] An exactly positionable linear drive, such as a traction spindle 40, which is interlockingly connected with the carriage 16, for example, or another worm gear, is particularly suited for this.

[0035] For supporting the turning bars 13, 14, if they are not to be arranged in a cantilevered manner, their respective ends 28 and 51 close to the guide roller 11, can be connected by means of a cross arm 42, for example by material contact. A left guide block 62 and a right guide block 63 are welded to the cross arm 42, each of which has a sliding bore. The guide blocks 62, 63 are threaded on the upper guide rod 59 with a close sliding fit. By means of this it is achieved that the two upper deflection devices 13, 14 can be displaced horizontally in the transverse running directions QR and QL.

[0036] The carriage 16 can be slid back and forth between the left short lateral frame 23 and the right short lateral frame 37 in the left and right transverse direction in such a way that the ends 28 and 66 of the upper turning bars 13, 14 near the deflection roller 11 can be displaced as fully as possible over the entire length of the deflection roller 11, or over the path of the maximal paper web width b54.

[0037] The turning bars 13, 14 can of course be “air blown” in the known manner, at least at the places of their shells around which a partial paper web loops.

[0038] The outside located, extreme lateral generating lines, right SML13 of the deflection device 13 and left SML14 of the deflection device 14 of the first (right) deflection device 13 and the second (left) deflection device 14, or their extensions, form an opening angle β=90°. The same applies to the farthest innermost lateral generating lines (for example left inner IML13 of the deflection device 13 and right inner IML14 of the deflection device 14), or their extension of the two deflection devices 13, 14 also preferably form an opening angle β=90 (with the narrowest possible tolerance range). The opening angle β is composed of the 45° complementary angle β13 and the complementary angle β14.

[0039] One of the legs of the complementary angle β14 lies on the lateral generating line SML14, or IML14, and the other leg on the median line 53 of the opening angle β.

[0040] The opening angle β (=β13+β14) opens opposite the running direction L of the partial paper webs 03, 04 entering into the deflection devices 13, 14, i.e. the angle opening points in the direction toward the guide roller 11. Therefore the complementary angle β13 also opens in the clockwise direction, and the complementary angle β14 in the counterclockwise direction, each opposite the running direction L.

[0041] In this case the highest generating line HML11 and the extension of the highest generating line HML13 form an angle of 45°, which opens in the direction toward the other deflection device 14.

[0042] In this case the highest generating line HML11 and the extension of the highest generating line HML14 form an angle of 45°, which opens in the direction toward the other deflection device 13.

[0043] If a paper web crosses below the deflection device 14 (in the exemplary embodiment represented in FIGS. 2, 6 and 7, for example), the lowest generating line TML13 of the deflection device 13 must lie in a third horizontal plane E3, which lies below the plane E1. The extreme right lateral generating line SML13 of the deflection device 13 lies in a vertical plane VE13 (not represented).

[0044] Both with the “left entry” and the “right entry”, the highest generating line HML14 of the left deflection device 14, and a highest generating line HML11 of the guide roller 11, and a highest generating line HML 13 of the right deflection device 13, can be located on the same horizontal plane, the plane E1 (FIG. 6). This is for example achieved in that the largest diameter of the deflection device 13 or 14, below which a partial paper web 03, 04 is to cross, is less than the diameter of the other deflection device 14 or 13, below which nothing crosses (assuming a circular diameter of the deflection rollers). Because of the different diameters of the deflection devices 13, 14, the lowest generating lines TML13 and TML14 of the participating deflection devices 13, 14 lie on planes E2 and E3 of different heights, which can have a distance a from each other which is less than the smallest diameter of the deflection devices 14 or 13, for example between 0.8 and 25 mm. The distance a mainly depends on the maximum paper thickness and type of paper to be printed and is fixed during the construction of the press (FIGS. 6 and 7).

[0045] Therefore the lowest generating line TML13 or TML14 of the deflection devices 13 and 14 must always be located on a higher plane E2 when it is intended that a partial paper web 03 or 04 is to cross below it on its way to the laterally arranged registration roller.

[0046] A third (lower) horizontally displaceable deflection device 29 is arranged below the two horizontally displaceable deflection devices 13, 14. Therefore it can be horizontally displaced in the left transverse running direction QL and the right transverse running direction QR, i.e. toward and away from the registration roller 18.

[0047] The displacement of the third deflection device 29 is designed in such a way that it can be displaced over its entire length along at least the entire width of the intended running path of the whole-width paper web 02 (M1.02, M2.02, M3.02, M4.02, M5.02, etc.) and, further than that, respectively in the direction toward the registration roller—in this exemplary embodiment toward the right—it can be moved toward the right completely out of the running path of the “whole-width” paper web 02, or out of the running path of the right “half-width” partial paper web 04.

[0048] An end 66 of the third deflection device 29—for example in the form of a turning bar 29—close to the deflection roller 11 is fastened on a third guide block 67 having a guide bore. The guide block 67 has been displaceably threaded via its bore on the lower guide rod 61 (linear guide). No separate drive mechanism is provided for the guide block 67. The other end of the turning bar 29, the end 64 remote from the deflection roller 11, is rigidly fastened on a second (fastening) carriage 31.

[0049] The (guide or) fastening carriage 31 with its guide 10 is arranged displaceably and can be fixed in place interlockingly along a straight guide device 32 (for example a dovetail guidance device), which can be a component of a cross arm 68, by means of a motor drive 33 with a gear. The cross arm 68, and therefore the straight guide device 32, extends horizontally between the left short lateral frame 23 and the right short lateral frame 37 and is fastened on the insides of the latter.

[0050] The electric servo motor 33, with an integrated angle of rotation transducer 38 motor drive 34 flanged to the left short lateral frame 23, is provided as the drive mechanism for the carriage 31. It is respectively used for determining the actual value of the position of the carriage 31, on which the deflection device 29 is fastened. Furthermore, an electronic control device with an arrangement for presetting a position reference variable, a device for performing the comparison of the reference variable with the actual value, and an actuating device for generating a manipulated variable to be fed to the drive 33, are provided. By means of this an accurate, and also presettable, positioning of the deflection devices 29 is possible.

[0051] An exactly positionable linear drive, such as a traction spindle 65, which is interlockingly connected with the carriage 31, for example, or another worm gear, is particularly suited for this.

[0052] Viewed in the running direction L, an extreme lateral (right) generating line SML29 and/or an extreme inner left generating line IML29 of the deflection device 29, or their extensions, always form an angle β29=45° with the running direction L. This angle β29 opens in the running direction L. This is always the case, regardless in which position in the QL or QR the third deflection device 29 might be if, viewed in the running direction L, the registration roller 18 is provided to the left of the left deflection device 14.

[0053] A vertical plane VE14 (not represented), in which the inner generating line IML14 of the left deflection device 14 lies, and a vertical plane VE29 (not represented), in the extreme lateral generating line SML29 of the third deflection device 29, always extend parallel with each other (FIGS. 1 to 3, 6, 7) in an arrangement wherein the registration roller 18 is arranged on the left and parallel with the running direction L.

[0054] However if—viewed in the running direction L—the registration roller 18 is arranged to the right of the right deflection device 13 (not represented), a vertical plane VE13, in which the inner generating line IML13 of the right deflection device 13 is located, and a vertical plane VE29, in which the extreme lateral inner (left) generating line IML29 of the third deflection device 29 lies, always extend parallel with each other.

[0055] Moreover, the extreme lateral (right) generating line SML29 and/or the extreme inner generating line IML29, or their extensions, always form an angle β29=45° with the running direction L, which opens opposite the running direction L, regardless of the position transversely to the running direction L in which the third deflection device 29 may be. In this case the position of the registration roller 18 in relation to the planes E3 and E4 does not change.

[0056] The lower turning bar 29 can be moved back and forth along its assigned cross arm 68 in such a way that its end 64, which is remote from the deflection roller 11, i.e. close to the deflection roller 15, can be moved close to the insides of the two bearing blocks 57, 58. This means that the partial paper web 04 (with left entry, FIG. 2), or the partial paper web 03 (with right entry, FIG. 3), which is deflected by the lower deflection device 29 in the direction toward the deflection roller 15, can be placed as desired (continuously) in the axial direction of the deflection roller 15. The deflection roller 15 has a minimum length which the total width of the side-by-side arranged plurality (for example three, four, etc.) of longitudinal folding devices. It follows from this that, depending on the entry selected, the partial paper webs 03 or 04, or 03L, 03R, 04L, 04R, etc. can be fed to any of the longitudinal folding devices preselected from the plurality of longitudinal folding devices of the folding apparatus 50.

[0057] With a “left entry” (FIG. 2), a left partial paper web 04 runs—viewed in the web running direction L—directly and without deflection into a transverse running direction QL, QR from the guide roller 11 directly over the deflection roller 24 (with or without touching it) to a deflection roller (longitudinal folding device entry roller). The latter guides the left partial paper web 04 in such a way that it enters the extreme left—of several, for example three—longitudinal folding devices of the folding apparatus 50, not represented.

[0058] The right partial paper web 03 runs up on the top on the highest generating line HML13 of the obliquely-placed right (upper) deflection device 13, loops around it and undergoes a change of its running direction in the process from the running direction L into a transverse running direction QL, extending transversely to the latter, in the direction toward the registration roller 18 arranged on the left. On its way to the registration roller 18, the transversely deflected right partial paper web 03 thereafter crosses below the left deflection device 14 at the distance a within the space between the higher plane E2, in which the lowest generating line TML14 of the deflection device 14, and the lower located plane E3, in which the lowest generating line TML13 of the right deflection device 14 are enclosed. Finally, on the highest generating line 18 in the plane E3 it runs up on the registration roller 18 arranged on the (left) and loops around it. It leaves the registration roller 18 at the lowest generating line TML18 in the plane E6 of the registration roller 18 and moves in the transverse running direction QR (extending transversely to the right of the running direction L) to the lower deflection device 29 placed obliquely at 45°. The right partial paper web 03 runs up on the lower deflection device 29 at the lowest generating line TML29 (in the plane E6) and leaves the deflection device 29 at the highest generating line HML29 (which is located in the plane E5 located above the plane E6) with the running direction deflected by 45° out of the running direction QR into the running direction L. From the third deflection device 29, the partial paper web 03 crosses without touching below an upper deflection roller 24, rotatingly seated in the short lateral frames 23, 37, and finally arrives at the lower deflection roller 15, rotatingly seated in the short lateral frames 23, 37 (deflection roller 15). The deflection roller 15 can be selectively accessed from the bottom or the top by the right partial paper web 03, as well as the left partial paper web 04 in order to feed the partial paper webs 03, 04 over a further deflection roller, not represented (hopper inlet roller) to any arbitrary longitudinal folding device selected, for example, from three devices, of the folding apparatus 50. Responsible for this is the freely selectable working position of the third deflection device 29 in relation to a longitudinal folding device (hopper), for example the first hopper arranged on the extreme right. As already described above, the third deflection device 29 can be selectably positioned in such a way that every partial paper web 03, 04, which is deflected by it, enters into the longitudinal folding device selected from a plurality, for example three, of a folding apparatus.

[0059] With “right entry” (FIG. 3), a right partial paper web 03 runs—viewed in the web running direction L—directly and without deflection in a transverse running direction QL, QR from the guide roller 11 via the deflection roller 24 (with or without contact with it) to a longitudinal folding inlet roller. The latter deflects the right partial paper web 03, without changing the main running direction L (production direction), in such a way that it enters through the selected “right entry” always “straight ahead” into the right outermost longitudinal folding device of the folding apparatus 50 which is located directly opposite the “right entry”.

[0060] The left partial paper web 04 (still FIG. 3), after it has left the highest generating line HML11 of the guide roller 11, moves in the web running direction L (=production direction) at a sufficient distance (for example 5 to 20 mm) over the greatest height of the deflection devices 13, 14 and runs up on the top of the upper deflection roller 24, which is rotatably seated in the lateral frames 23, 37, loops around it and leaves it at its lowest generating line TML24 (plane E1 or E7) of the deflection roller 24 in order to finally run up, against the running direction L, on the highest generating line HML14 (plane E1 or plane E7) on the left deflection device 14. Then the left partial paper web 04 passes over the extreme inner generating line IML14 of the deflection device 14, placed obliquely at 45°, and leaves it from its lowest generating line TML14 (plane E2) in the left running direction QL and runs to the left registration roller 18. The left partial paper web 04 deflected into the left transverse running direction QL then runs up on the registration roller 18 on the highest generating line HML18 (plane 3) of the latter. Then the left partial paper web 04 is deflected by the registration roller 18 and leaves it at its lowest generating line TML18 (plane E6) in the right transverse running direction QR and finally arrives at the third (lower) deflection device 29 at the lowest generating line TML29 (plane E6) of the latter. The partial paper web 04 loops around the lower deflection device 29 while changing its running direction from the running direction QL to the running direction L. It crosses without contact below the upper deflection roller 24 and arrives at the deflection roller 15 arranged below the deflection roller 24. The latter deflects the partial paper web 04, depending on whether the longitudinal folding devices are arranged high or low, upward or down onto the deflection roller (=hopper inlet roller) of the folding apparatus 50 depending on the position in which the lower deflection device 29 has been positioned transversely to the running direction L. This means that the left partial paper web 04 can selectively enter any of the longitudinal folding devices of the plurality of longitudinal folding devices of the folding apparatus 50; for example, it can also enter below the right paper web 03 into the extreme right longitudinal folding device.

[0061] It is also possible that the highest generating lines HML13 and HML14 of the deflection devices 13, 14 are located on different horizontal planes E1 and E7.

[0062] A highest generating line HML14 of the turning bar 14 and a highest generating line HML11 of the guide roller 11 can be located on the same horizontal plane E1, wherein in this case the highest generating line HML11 and its extension and the extension of the highest generating line HML14 form an angle of 45° opening toward the left, viewed in the running direction of the paper web, or partial paper webs 03, 04 (or even more) entering on the guide roller 11. Their lowest generating line TML14 lies in a second horizontal plane E2, located at a distance a above the plane E3. As already stated above, the distance a can lie between 0.8 and 20 mm. It is achieved by means of this short distance a that a partial paper web 03, 04, in the exemplary embodiment the partial paper web 03 (FIG. 1), on its way from the guide roller 11 via a 45° deflection device, for example the left deflection roller, to a linear registration device, for example a registration roller, for example 18, can move, “saving structural height”, below the other turning bar, here the turning bar 14, as closely as possible to it and without contacting it.

[0063] The extreme lateral generating line SML14 is located in a vertical plane VE14.

[0064] The arrangement wherein the highest generating lines (HML13 and HML14) of the 45° deflection devices 13, 14 lie in the same horizontal plane (E1) is selected when the deflection device 13 or 14, below which a web crosses, is intended to have a lesser diameter than the deflection device 14 or 13, below which nothing crosses.

[0065] However, the highest generating line HML14, or HML 13 can also lie on a horizontal plane E7 (seventh plane), which is located above the first plane E1 of the highest generating line HML11 of the guide roller 11. This position arrangement is selected when the turning bars 13, 14 are to have the same circular cross section (diameter) and the above mentioned distance a is to be achieved (FIG. 7).

[0066] The vertical plane VE13 intersects the generating line HML11, or its extension, angle of 45° open toward the right.

[0067] The vertical plane VE14 intersects the generating line HML11, or its extension, angle of 45° open toward the left.

[0068] The lowest generating line TML13 and the highest generating line HML18 of the registration roller 18 lie in the same horizontal plane, the third plane E3.

[0069] The lowest generating line TML29 of the individual 450 deflection devices, for example the turning bar 29, and the lowest generating line HML18 of the registration device, for example the registration roller 18, lie in the same horizontal plane, the sixth plane E6.

[0070] The highest generating line HML18, and preferably also the lowest generating line TML18 lie in a vertical plane VE18. The extensions of HML14, SML14, IML14, TML14, ILM29, HML29, SML29, TML29 intersect—viewed in a counterclockwise direction—at an angle of 135°; SML 13, IML13, HML13 at an angle of 45°. In this case the registration roller 18 is arranged on the “left”—viewed in the running direction L.

[0071] If—viewed in the running direction L—the registration roller 18 is arranged on the “right”, the extensions of HML13, SML13, IML13, TML13, ILM29, HML29, SML29, TML29 intersect the vertical plane VE18—viewed in a counterclockwise direction—at an angle of 45°; SML14, IML14, HML14 at an angle of 135°.

[0072] The highest generating line HML29 of the 45° deflection device 29 is located in the horizontal plane E5, the fifth plane. It lies below the plane E4.

[0073] The vertical plane VE29, in which the extreme right lateral generating line SML29 lies, intersects the generating line HML11, or its extension—viewed in the running direction of the paper web, or partial paper webs running up on the guide roller 11—at an angle of 45°, opening toward the left.

[0074] Thus, the registration roller 18 can be arranged not only on the side of the left deflection device 14, but also on the side of the right deflection device 13.

[0075] In the deflection modules 05 (=Ml, M2, M3, M4, M5, etc.) the left first and the right whole-page frames (lateral frames 06, 09, 58, and the lateral frames 07, 08, 57) are spatially separated and are arranged spaced apart from the short left second lateral frames 23 and right second lateral frames 37 (FIGS. 1, 4).

[0076] In all whole-page frames or lateral frames the devices and units arranged on, in and between them (as represented in FIG. 1), can be preassembled into a “deflection module” 05 (M1, M2, M3, M4, M5, etc.). On their upper and lower, all lateral frames are worked so accurately that several identical whole-page frames or lateral frames (06, 09, 58, and 07, 08, 57 and 37 and 23), and therefore several “deflection modules” (05, M1, M2, M3, M4, M5, etc.) are stacked on top of each other and releasably connected to each other (for example screwed together), so that a “deflection device tower” results, such as represented in FIG. 5, for example.

[0077] The “whole-width” paper web 02 can, for example, also be longitudinally cut into more than two partial paper widths of equal width or of different widths 03, 04, depending on the number of longitudinal cutting devices 12 provided. For example, the “whole-width” paper web 02 can be longitudinally cut into the “half(web)-width” partial paper widths 03 and/or 04, in “quarter (web-width” partial paper webs 03L, 03R and/or 04L, 04R. The partial paper webs are then conducted over deflection devices 13, 14, 18, 29 over the rollers 24, 15, 73 to the folding apparatus 50.

[0078] From the upper deflection rollers 24 and the lower deflection rollers 15, the partial paper webs 03, 04, 03L, 03R, 04L, 04R, etc. can be conducted to a guide roller 73 specifically assigned to it in a separate roller housing frame 20. The roller housing frame 20 consists of two lateral frames, in which a plurality of guide rollers, arranged on top of each, are rotatably arranged (FIG. 5).

[0079] The axes of rotation of the guide rollers 73 arranged on top of each other are offset horizontally and vertically in such a way that the individual partial paper webs cannot interfere with each other in the course of their entry into the folding apparatus 50. The partial paper webs can run from above or below on the guide rollers 73, depending on whether the folding apparatus inlet is arranged below or above the lowest module M1.

[0080] A roller frame 25 with two lateral frames is arranged laterally to the left and above the topmost module M1. A plurality of guide rollers 72 is rotatably seated, spaced apart from each other and on top of each other, in the lateral frames of the roller frame 25. One guide roller 72 is provided per entering paper web 02, M1.02, M2.02, M3.02, M4.02, M5.02, etc. The roller frame 25 can be arranged above the topmost module, for example M5, on two longitudinal supports on the upper assembly plane 43. In this case the paper webs run, coming from above, at the bottom onto their respectively assigned deflection roller in the module.

[0081] If, coming from below, the incoming paper webs 02, M1.02, M2.02, M3.02, M4.02, M5.02, etc. are to run up from above onto their respectively assigned deflection roller 30 in the respective modules, the roller frame 25 can also be arranged on the lower assembly plane 46.
