Description




FIELD OF THE INVENTION




The present invention is directed to a method and to a device for drawing in a web in a web-fed rotary printing press. The web has a draw-in tip which is made thicker than the rest of the web.




BACKGROUND OF THE INVENTION




A device for attaching a web of material to a carrier of a web draw-in device is known from EP 0 118 860 B1. A fastening device, that receives the end of the web of material, is loosely suspended by a loop fastened on the former from the carrier, of a draw-in element.




A draw-in device is described in G 92 15 764 U1, in which a cable, which is attached to the draw-in tip, is pushed vertically in respect to the conveying direction into the openings of carriers. The cable is maintained on the carrier, secure against slipping out opposite the conveyance direction, by the use of a headpiece of the cable.




DE 198 37 361 A1 discloses a device for drawing in a web of material to be imprinted. A free end of the draw-in tip is threaded through an opening of a carrier which is connected with the draw-in device and is made into a loop by a hook-and-loop closure.




EP0 425 741 A1 shows a device for drawing in a web and having a draw-in assembly. A positive connection opposite and transversely to the conveying direction with a carrier arranged on the draw-in assembly can be made by the use of a coupling element arranged on a draw-in tip. The coupling element, embodied in a stepped manner, and the carrier can be connected with each other, or released from each other, by a relative movement along the conveying direction.




SUMMARY OF THE INVENTION




The object of the present invention is based on providing a method and a device for drawing in a web.




In accordance with the present invention, this object is attained by providing the web to be drawn in with a thickened portion. This thickened portion is received in a carrier that is part of the web draw-in device. The thickened portion is slid into the carrier in a direction perpendicular to the web conveying direction and is then moved in the carrier in a direction parallel to the conveying direction. This second movement takes place with limited travel in the direction perpendicular to the conveying direction.




The advantages which can be realized by the present invention reside, in particular, in that the connection between the draw-in assembly or device and the draw-in tip is positive in the conveying direction, which connection is embodied in a self-securing manner in respect to releasing the connection during the operation, i.e. when drawing the web in. The danger of a spontaneous and unintentional release of the connection, such as can occur in a connection with simply designed carriers, is reduced by a travel limitation imposed on the draw-in tip on all sides of the tip, which is closed to a great extent.




The connection between the draw-in tip and the draw-in assembly or device is substantially achieved in an advantageous manner by the requirement of a two-step movement, which movement is guided to a great extent, of the draw-in tip in respect to the carrier. In an advantageous manner, the suspension and securing of the tip in the carrier takes place in two defined movement directions, which extend almost perpendicularly with respect to each other. In a first step, the suspension of the tip in the carrier takes place in a direction which is almost perpendicular in respect to the web conveying direction. In a second step, the connection is secured by a relative movement between the clamping element and the draw-in tip in which the tip moves relative to the clamping element in a direction opposite to the web conveying direction. The movement, which is guided to a great extent and which extends almost perpendicularly in respect to the conveying direction for a suspension in a narrowly bordered forward direction provides increased assurance against unintentional release of the tip from the carrier.




In a particularly advantageous embodiment, a sequence of two defined movements is required for connecting, or releasing the tip and the carrier, wherein one movement represents a rotational movement, which movement is not one typically occurring in the draw-in process, in a direction R. With this sequence of movements, the connection is not sensitive to unintentional release because of fluctuations in the web tension or in web speed during draw-in.




In at least one area in which the draw-in tip, or a thickening at the draw-in tip, and the carrier engage each other, a first movement is possible only guided along in a direction which is predetermined to a great extent.




In addition to providing a high degree of assurance that the connection will not become undone, a substantial advantage of the present invention is its rapid and simple operability. Elaborate opening or closing by the use of tools, gluing or threading into closed eyes is not required.

DESCRIPTION OF THE PREFERRED EMBODIMENTS




Drawing-in of webs, for example webs of material to be imprinted in web-fed rotary printing presses, takes place, in a generally known manner, by the operation of a web draw-in device


01


, for example such as a chain


01


, a belt or a cable, as depicted somewhat schematically in FIG.


1


. As a rule, the chain


01


is located adjacent the side of the paper web to be drawn in and is conveyed through the printing press, for example on a rail, along a path provided for the paper web. A carrier


02


is arranged on the chain


01


, and on, or to which a start


03


of the paper web is fastened. The chain


01


may be embodied as a roller chain


01


with rollers


09


, for example.




In the embodiment depicted in

FIG. 1

, the start


03


of the paper web is configured as a draw-in tip


03


, which is connected with the paper web, and whose free end


04


can be positively connected with the carrier


02


which is supported by chain


01


to move in the conveying direction T. The draw-in tip


03


can be in the form of a foil which is connected with the paper web, a reinforced end of the paper web itself, a single- or multi-part reinforcement or extension, which is connected in a non-positive manner, in a positive manner or is incorporated into the material. In an advantageous manner, the draw-in tip


03


extends in the conveying direction T at an acute angle toward the laterally arranged chain


01


, and is embodied, at least in the area of the connection with the chain


01


, or the carrier


02


, in a manner which is substantially tear-resistant, for example as a metal or as a plastic strip. The draw-in tip


03


is flat and flexible and has a reduced thickness d


03


, as seen in

FIG. 3

, wherein preferably d


03


<1.5 mm, for example d


03


=0.5 mm. Draw-in tip


03


preferably extends on a conveying plane. The conveying plane is understood to be that plane whose length extends in the conveying direction T on the plane of the carrier


02


through the conveying direction T and the imagined position of the web.




On its free end


04


, the draw-in tip


03


has a thickening or an enlargement


06


formed in a direction with respect to the web and to the web draw-in tip


03


which direction is almost perpendicular with respect to the conveying direction T and which draw-in tip


03


acts together, in a positive manner, with the carrier


02


in the course of the draw-in of the web in the conveying direction T. The thickening or enlargement


06


can be a raised bump generated by forming or by embossment, as seen in

FIG. 6



a


, by the provision of a pin or bolt penetrating the draw-in tip


03


, as seen in

FIG. 6



b


, or as any other raised section, which causes an increase of the cross-section of the draw-in tip


03


in respect to a direction perpendicular with respect to the conveying direction T. The shapes of the cooperating carrier


02


and the draw-in tip thickening


06


are reciprocally provided in such a way that a suspension, which is guided to a great extent, and a connection between the carrier


02


and the draw-in tip


03


with the thickening


06


takes place, which suspension and connection is limited in at least five of the six spatial directions, and in one embodiment of the invention, in six of the six spatial directions. A movement, that is guided to a great extent, is required along part of the connective path, at least in the area in which the carrier


02


and the draw-in tip


03


, or the thickening


06


, penetrate each other. Because of the reciprocal shaping of the tip


03


and the carrier


06


, the connective movement between the two takes place within a narrow angular range. Two examples from the multitude of possible options have been taken in what follows and will be described in greater detail.




In the first example, the thickening


06


, as depicted in

FIG. 6



c


, is embodied as a head of a screw


07


which screw


07


is extending perpendicularly through a recess, not specifically represented, in the draw-in tip


03


with the screw head situated on one side of the draw-in tip


03


and, on the other side of the tip


03


, as a nut


08


, which is, for example, fixed against relative rotation, and which is cooperating with the screw


07


. The free end


04


of the draw-in tip


03


, as provided with the thickening


06


described above, cooperates with the carrier


02


of the chain


01


when the paper web is drawn in, as depicted in FIG.


1


.




At least at its end


11


that is trailing in the conveying direction T, as seen in

FIG. 1

, the carrier


02


is provided with a slit


12


extending approximately parallel with the conveying plane. In the preferred embodiment, the carrier


02


is embodied for this purpose as a two piece clamping element


02


with a first cheek or segment


13


and a second cheek or segment


14


, which two segments


13


and


14


are connected with each other by two screws


16


extending almost perpendicularly in relation to the slit


12


. To provide the slit


12


with a height h


12


, it is possible to arrange a spacer element between the segments or cheeks


13


and


14


, for example. However, the segments or cheeks


13


and


14


can also be offset from each other on their sides respectively facing each other, so that a slit


12


is created when they are brought together. A one-piece embodiment of the carrier or clamping element


02


is also possible, wherein the slit


12


is embodied as a sawn cut, for example. In the configuration of the carrier


02


shown in

FIG. 3

, the height h


12


of the slit


12


is defined by two bolts


23


, which connect the clamping element


02


with the chain


01


and which are arranged between the two segments


13


and


14


.




In the area of its trailing end


11


, the clamping element


02


has an elongated hole or aperture


18


that is passing, almost perpendicularly with respect to the conveying direction T, through both segments or cheeks


13


and


14


, and which aperture


18


extends at least partially along its length l


18


in the conveying direction T.




The outer lateral side


19


of the clamping element


02


has a recess


21


, for example a bore


21


, with side


19


being opposite the chain


01


. The bore


21


is arranged in such a way that it connects the outer side


19


with the elongated hole or aperture


18


at the the end of the elongated hole or aperture


18


which is remote from the draw-in tip


03


.




The bore


21


has a diameter d


21


, which corresponds at least to the largest cross section of the thickening


06


, and at least to the largest of the dimensions of the length l


06


and the maximum diameter d


06


of the thickening


06


constituted by the screw


07


and the associated nut


08


. The elongated hole or aperture


18


also has a width b


18


, as seen in

FIG. 2

, which corresponds at least to the maximum diameter d


06


of the thickening


06


. The length l


18


of the elongated hole or aperture


18


is greater than the diameter d


21


of the lateral bore


21


. Preferably, the length l


18


is greater than the sum of the diameter d


21


of the bore


21


and half the maximum diameter d


06


of the thickening


06


.




If the thickening


06


is embodied as a pin


06


penetrating through the draw-in tip


03


perpendicularly, as seen in

FIG. 6



b


, the diameter d


21


of the bore


21


is selected to be at least equal to the length l


06


of the pin


06


, and the width b


18


to be at least equal to the diameter d


06


of the pin


06


. Thus a lateral interior wall


22


, extending in the direction of the length l


18


, of the elongated hole


18


acts, together with the thickening


06


, to form a detent


22


. The width b


18


of the elongated hole


18


can also taper towards the trailing end


11


of the clamping element


02


in such a way that a frictional connection between the thickening


06


and the clamping element


06


is provided by the tensile force directed in the conveying direction T.




The height h


12


of the slit


12


, as seen in

FIG. 3

, is at least equal to the thickness d


03


of the draw-in tip


03


, and is less than the length or the height l


06


of the thickening


06


, so that the draw-in tip


03


can be guided into the slit


12


, at least in the area of the draw-in tip free end


04


, but that the thickening


06


, together with the slit


12


, and almost all of the entire interior wall


22


, with the exception of the bore


21


, constitutes the detent


22


.




In one embodiment of the present example, as seen in

FIG. 2

, the draw-in tip


03


is provided with a second thickening


17


, for example a casing of the draw-in tip


03


in the form of a woven tape. This thickening


17


on the draw-in tip


03


is spaced away from the first thickening


06


at a distance a


17


and in a direction opposite the end of the draw-in tip


03


. Advantageously, the distance a


17


is less than a distance a


21


of the recess


21


, but must at least be selected to be as large as an inner width l


18


of the longitudinal hole


18


from the side


19


of the clamping element


02


.




During operation, i.e. in the suspended state of the draw-in tip


03


in the clamping element


02


, the thickening


06


is connected together with the end


04


of the draw-in tip


03


and their travel is limited in six directions. In the preferred embodiment, the draw-in tip


03


is positively connected in all directions perpendicular in respect to the conveying direction T and is movable parallel in respect to the conveying direction T, but its travel is limited. In the embodiment with the draw-in tip


03


having the second thickening


17


, the freedom of movement of the draw-in tip


03


in the conveying direction T is additionally limited and, for releasing the connection, the draw-in tip


03


initially makes a rotation in the direction R, as seen in

FIG. 2

, around an axis which, in an advantageous manner, extends almost perpendicular in respect to the conveying direction T. In the tightened state in particular, for example during drawing in of the web in the conveying direction T, the thickening


06


is also positively, or at least with limited travel, connected opposite to a suspension direction E parallel in respect to the longitudinal axis E of the bore


21


, which represents the direction in which the thickening


06


is conducted into the clamping element


02


in the course of suspending the draw-in tip


03


.




The clamping element or carrier


02


is releasably fastened to the chain


01


by use of the two bolts


23


, or screws


23


. In an advantageous manner, a spacing distance a


23


between the bolts


23


in the conveying direction T, as seen in

FIG. 3

, is a whole number multiple of the distances between the shafts of two roller


09


of the chain


01


.




In a second preferred embodiment of the device for drawing in a web, as seen in

FIG. 4

, the thickening


06


is embodied as a bead


06


on the free end


04


of the draw in tip


03


, as seen in

FIG. 6



d


. This bead


06


can be, for example, a small tube


24


, as shown in

FIG. 6



d


that is worked into the end


04


of the draw in tip


03


, or as a pin or a groove, as shown in

FIG. 6



a


, that is formed in the draw in tip


03


during its manufacture. The bead


06


extends in the conveying plane almost perpendicular in respect to the conveying direction T.




As in the first preferred embodiment, this bead


06


cooperates positively with an elongated hole


26


formed in the carrier


02


in a manner in which it limits travel, and in the conveying direction T. The elongated hole


26


of the second preferred embodiment, as depicted in

FIG. 4

, does not extend perpendicularly, in respect to the conveying plane, and to the bore


21


, through a clamping element


02


, but instead is almost parallel with the conveying plane. Over its length l


26


, the elongated hole


26


extends nearly parallel in respect to the conveying direction T. To prevent the bead


06


from slipping laterally out of the elongated hole


26


, the elongated hole


26


is discontinuous on the lateral outer side


19


of the clamping element


02


; i.e. the side of the clamping element opposed to the chain


01


, so that a projection


27


remains on the side


19


as a detent


27


. This lateral projection


27


is located on the side of the elongated hole


26


which is closer to the trailing end


11


of the clamping element


02


and thus prevents the suspended thickening


06


of the draw-in tip


03


from sliding out of the clamping element


02


in a direction opposite to the suspension or attachment direction E. The portion of the elongated hole


26


which is continuous on the outer lateral side


19


corresponds to the recess


21


in the first preferred embodiment that is required for suspending the draw-in tip


03


. On the side facing the chain


01


, the elongated hole


26


can be continuous. As a rule, the draw-in tip


03


is prevented from sliding out of this side of the clamping element


02


by the adjoining chain


01


which thus also serves as a travel limiter.




In a preferred embodiment, the elongated hole


26


can be configured as an elongated hole


26


which conically tapers in a direction opposite the conveying direction T, and which is provided with a frictional connection by the thickening


06


, in addition to the travel limitation, when the clamping element


02


and the draw-in tip


03


are moved relatively away from each other in the conveying direction T.




The elongated hole


26


can also be arranged in the clamping element


02


in such a way that its length l


26


does not extend parallel in respect to the conveying direction T, but is inclined in relation to the conveying direction T at an angle α which is not equal to 0° against the conveying direction T. In this preferred embodiment, as indicated in

FIG. 5

, the inclination α between the orientation of the elongated hole


26


of the length l


26


and the conveying direction T is approximately 20°. This embodiment can be selected, for example, for assuring even more security against the thickening


06


laterally slipping out of the longitudinal hole


26


, but also, if required, to point in the direction of a resultant line for the tensile force.




In a configuration that is suitable for use with both preferred embodiments, the thickening


06


on the draw-in tip


03


is formed as a ball


06


or as a cylinder


06


which are arranged on one end of a belt


28


or cable


28


, which in turn has been incorporated into the draw-in tip


03


as seen in

FIG. 6



e


. In actual use, a steel cable


28


with a steel ball


06


or a steel cylinder


06


, for example a Bowden cable


06


,


28


, is preferable. When using a cylindrical thickening


06


, in the first preferred embodiment an axis of the cylindrical thickening


06


is oriented nearly perpendicularly in respect to the paper plane. In, in the second preferred embodiment this axis is oriented nearly parallel with the paper plane.




The embodiment in accordance with

FIG. 6



e


can be modified in an advantageous manner in that additionally a bolt


29


, or, for example, a pin


29


, is arranged on the thickening


06


, which designed as a ball


06


. This bolt or pin is shown in dashed lines in

FIG. 6



e


, since this is optional. In the suspended state, this pin


29


is used for securing the ball


06


in the recess


18


. The pin


29


is oriented, for this purpose, in such a way that, in the suspended end state, its longitudinal direction extends perpendicular in relation to the plane of the slit


12


. If the recess


18


, the bore


21


and the slit


12


are aligned as represented in

FIG. 1

, the pin


29


extends perpendicular to the paper plane, or to the plane of the draw-in tip


03


. If the arrangement is rotated by 90°, the pin correspondingly extends in the paper plane, or the plane of the draw-in tip


03


.




In this embodiment, four different movements, of which two are guided translatory movements and two are rotatory movements, are required for suspension. Initially, the ball


06


must be inserted along the suspension direction E, as seen in

FIG. 2

, laterally into the bore


21


in such a way that the pin


29


is guided through the slit


12


into the interior of the recess


18


. To do this, a diameter d


29


, or a thickness d


29


, of the pin


29


must be less than the height h


12


of the slit


12


. Then the ball


06


with the pin


29


must be turned by approximately 45° in the recess


18


around an axis along the insertion direction E. Thereafter, the translation opposite the conveying direction T and a rotation in the direction R around an axis which is nearly perpendicular in respect to the conveying direction and the insertion direction E can take place.




The configuration of the thickening


06


and of the cooperating bore


21


, or the recesses in the form of elongated holes


18


,


26


, or differently shaped recesses


18


,


26


in the carrier or clamping member


02


is possible in a multitude of ways in order to make possible a guided suspension in the suspension direction E of the draw-in tip


03


perpendicularly to a great extent, or with a component perpendicular to the conveying direction T, and the travel limiting securing of the draw-in tip


03


in the carrier


02


against movements in a direction perpendicular to the conveying direction T. It is advantageous that the clamping element


02


is provided with a recess


18


, or


26


, which has at least one component of the diameter, or the inner width l


18


or l


26


in the conveying direction


26


, which is greater than the corresponding component of the diameter, or the inner width d


21


of the recess


21


, which is required for the suspension and which is connected with the recess


18


or


26


. Because of the separation of the movements for suspension and for securing, a travel limitation is also provided in directions perpendicular to the conveying direction T, in particular also counter to the suspension direction E.




The mode of functioning of the device for drawing in a material to be imprinted, in accordance with the present invention is as follows:




For drawing in a web of material to be imprinted, its start is provided with a draw-in tip


03


, which has a thickening


06


on its free end


04


. This free end


04


of the draw-in tip


03


, with the thickening


06


, is pushed, in the suspension direction E, into the recess


21


. Simultaneously the end


04


of the draw-in tip


03


is slid into the slit


12


of the clamping element


02


. By a movement of the draw-in tip


03


in a direction opposite to the conveying direction T, or a movement of the clamping element


02


in the conveying direction T, the thickening


06


slides in the elongated hole


18


, or


26


, in the direction toward the trailing end


11


of the clamping element


02


. The position of the free end


04


of the draw in tip


03


is thus secured in all of the conveying direction T, or the course of the elongated hole


18


in the conveying direction, against slipping out laterally. After the web of material to be imprinted has been drawn in, the release and removal of the draw-in tip


03


takes place in the reverse order. When removing the draw-in tip


03


with a second thickening


17


at the previously mentioned distance a


17


from the thickening


06


, an additional relative rotation in a direction R between the draw-in tip


03


and the clamping element


02


is required for the suspension, or release of the draw-in tip


03


.




While preferred embodiments of method and of a device for drawing in a web, in accordance with the present invention have been set forth fully and completely hereinabove, it will be apparent to one of skill in the art that a number of changes, for example, in the type of printing press being used, the structure of the draw-in chain and the like could be made without departing from the true spirit and scope of the present invention which is accordingly to be limited only by the following claims.
