Abstract
A device for feeding a web of material utilizes a pair of low angle bar superstructures situated adjacent to each other. Two cross or transverse folding devices are situated on the same or on different planes after, in the direction of web travel, the superstructures. Wide webs of material can be processed and if one of the transverse folders fails, production can be shifted to the other folder.
Description
The invention relates to a feeding device for a web of material in accordance with the preamble of claim
1
.
Paper web feeding devices consisting of a first and second superstructure, between which an unencumbered connecting partial paper web guide chute, which is bordered by paper guide rollers, is arranged, are known from DE 94 21 467 U1. A longitudinal folding device for so-called “funnel production”, or a draw-in device for so-called “magazine production”, are selectively provided between the superstructures and a web inlet of the folding device, or of the transverse folding device.
DE 296 17 976 U1 discloses a feeding device for a web of material for two folding devices, wherein two superstructures are arranged one above the other.
The object of the invention is based on providing a feeding device for a web of material for a folding device.
The object is attained in accordance with the invention by the means of the characteristics of claim
1
.
The following advantages in particular are achieved by means of the invention: only short paths are needed for guiding the partial webs of material because of the guidance of two partial webs of material on a horizontal level of the two-part superstructure and using respectively only one turning bar. A low structural height of the superstructure is achieved in this way which, in turn, leads to the reduction of the total height of the web-fed rotary printing press. The number of production variations is increased by the use of two transverse folding devices. The ability to vary the products is increased by means of the selective use of two arranged longitudinal folding devices, or of two arranged draw-in devices for funnel production or for magazine production, along with a low structural height of the two-piece compact superstructure, which exists anyway.
A reduced technical outlay also occurs because the feeding device for the webs of material can be used for both types of production mentioned above. It is advantageously possible to process wide webs of material with two transverse folding devices.
With an arrangement of two transverse folding devices oriented in the same direction it is possible in case of the outage of a first transverse folding device to provide a replacement function, without changing the plate on the printing cylinder, by using the second transverse folding device.
Exemplary embodiments of the invention are represented in the drawings and will be described in greater detail in what follows.
Shown are in:
FIG. 1
, a schematic plan view of feeding device for webs of material for two folding devices, selectively for funnel production or magazine production, wherein the folding devices are arranged on a common level,
FIG. 2

, to a connecting partial paper web guide chute
51
, on whose two chute sides
52
,
53
the guide rollers
54
to
65
, which are fixed in place in the lateral frames, are respectively provided per partial paper web guide group B
1
to B
6
, as well as A
1
to A
6
, for the vertical diversion of the partial paper webs
4
to
15
. The guide rollers
54
to
65
are each embodied as separately driven draw rollers, but are called guide rollers in the following description. Thus, guide rollers, register rollers, as well as a plurality of turning bars, for example two turning bars, are arranged on each level A
1
, B
1
to A
6
, B
6
. In this case, the partial paper webs
4
to
9
, which are conducted at the first chute side
52
over the guide rollers
54
to
59
are combined into a first partial paper web strand
67
, and the partial paper webs
10
to
15
, which are conducted at the second chute side
53
over the guide rollers
60
to
65
, are combined into a second partial paper web strand
68
.
The two partial paper web strands
67
,
68
are each conducted at the lower end
69
of the partial paper web guide chute
51
over guide rollers
71
,
72
, fixed in the lateral frames, and over pairs of draw rollers
73
,
75
to draw units C, D located on a machine level underneath the superstructures A, B.
Each one of the draw units C, D is used for “magazine production” and consists of a pair of draw rollers
74
,
76
.
The pairs of draw rollers
74
,
75
are spaced apart from each other at least horizontally, and can be located in separate lateral frames, not represented. Each one of the draw units. C, D is respectively located on a level above a strand inlet E, or F, of two transverse folding units G, H located on the lowest level L (FIG.
1
).
The transverse folding units G, H located on a common level are placed “back to back”, and their delivery belts each point in opposite directions (FIG.
1
). It is also possible for the transverse folding units G, H to be arranged one behind the other, and for their delivery belts to point in the same direction. Finally, it is possible to arrange both transverse folding units G, H next to each other in the axial direction.
The transverse folding units G, H can be embodied as so-called jaw folders or as so-called wheel folders.
The strand inlet E, F of each transverse folding unit G, H consists of a pair of draw rollers
78
,
79
for drawing in one of the two partial paper web strands
67
,
68
, as well as of a known transverse strand cutting device
81
,
82
of the transverse cutting unit G. H.
All shafts, or axes, of the register rollers
39
to
50
, as well as of the guide rollers
54
to
60
, the guide rollers
71
,
72
, of the rollers of the strand inlets E, F, as well as of the transverse strand cutting device
81
,
82
, extend with their axes parallel to each other and at right angles to the shafts, or axes, of the print units of the web-fed rotary printing press.
The partial paper web guide chute
51
, which separates the two superstructures A, B to form the partial paper web strands
67
,
68
receives the guide rollers
54
to
59
, as well as
60
to
65
, which are arranged above each other on its chute sides
52
,
53
, of the superstructures B, A, wherein the guide rollers
54
to
59
of the superstructure B are located on a level
86
, and the guide rollers
60
to
65
of the superstructure A are located on a level
85
. Both levels
85
,
86
intersect a horizontal line
84
at an acute angle alpha
1
, alpha
2
, and can extend parallel with each other. Viewed in the running direction of the partial paper webs
9
to
15
, a paper guide roller
87
to
89
is respectively arranged ahead of the guide rollers
59
to
65
in order to achieve an improved looping of the paper web around the associated guide rollers
59
to
65
.
When operating as a “magazine production”, the operation of the paper web feeding underneath the superstructures A, B is as follows: coming from the pair of draw rollers
73
, the first partial paper web strand
67
runs through the left draw unit C and can be introduced over a paper guide roller
83
into the left strand inlet E of the left transverse folding unit G.
In the same way it is possible, to conduct the second partial paper web strand
68
coming from the pair of draw rollers
75
over the right draw unit D and a paper guide roller
94
into the right strand inlet F to the right transverse folding unit H.
However, it is also possible to assign the left partial paper web strand
67
via a paper guide roller
101
to the right draw unit D, and therefore to the strand inlet F and the right transverse folding unit H.
Moreover, the second partial paper web strand
68
can be assigned via a paper guide roller
102
to follow the left strand inlet E, and therefore to the left transverse folding unit G.
It is of course also possible to operate as a so-called “funnel production” with the configuration of the paper feeding device represented in
FIG. 1
, which is performed analogously to the remarks regarding FIG.
2
. In this case the partial paper webs
4
to
15
are conducted over the funnel inlet group M of the longitudinal folding units I, K.
In case it is intended to operate as a so-called “funnel production”, i.e. longitudinally folded partial paper web strands are produced from wider partial paper webs, which are subsequently intended to be transversely cut and transversely folded, then in accordance with
FIG. 2
a printed paper web, for example of the width of a printing cylinder, of a width b is longitudinally cut into, for example, five partial paper webs
96
to
100
of equal width. The partial paper webs
96
to
100
are conducted to the superstructures A, B (same parts have the same reference numerals), wherein the partial paper webs
96
,
97
,
98
are turned on the turning bars
24
,
27
,
29
in the partial paper web guide groups B
1
, B
4
, B
6
on the left side of the partial paper web guide chute
51
and are horizontally guided, and the partial paper webs
99
,
100
are turned on the turning bars
30
,
35
in the partial paper web guide groups A
1
, A
6
on the right side of the partial paper web guide chute
51
and, as already described above, are conducted in an approximately vertical direction to the lower end
69
of the partial paper web guide chute
51
. In the process, a common paper web strand
103
is formed, which is conducted over a guide roller
71
to a left longitudinal folding unit I located on a machine level underneath the superstructures A, B.
It would also be possible, to provide a right partial paper web strand
105
, constituted by the partial paper webs
100
and
99
, over the guide roller
72
to a right longitudinal folding unit K, which is located on the same level as the left longitudinal folding unit I.
Finally, it is also possible to conduct the paper web strand
103
coming out of the two superstructures A, B to the right longitudinal folding unit K.
The two longitudinal folding units I, K are arranged mirror-inverted in respect to a level
106
extending between them, and are therefore provided with the same reference numerals.
Each longitudinal folding unit I, K consists of a known longitudinal folding funnel
107
with two pairs of funnel inlet rollers
108
,
109
arranged above it, only one roller of which is shown. The elements
107
,
108
,
109
of the longitudinal folding unit I, K are located in a separate frame, not represented. The frame also receives a funnel inlet group M respectively located above the longitudinal folding units I, K, and consists of five turning bars
113
to
117
arranged above each other. Five paper guide rollers
120
to
124
, which are fixed in place in the frame and extend axis-parallel with the guide roller
71
, are arranged upstream of the turning bars
113
to
117
on the same horizontal level, and paper guide rollers
131
to
135
, located on the same horizontal level, are arranged downstream from them. In this way the partial paper webs
96
to
100
, which are fed in from the superstructure A, B as a paper web strand
103
, are separately conducted by the paper guide rollers
120
to
124
of the funnel inlet group M of the longitudinal folding unit I through 90° from the vertical into a horizontal direction, turned by means of the turning bars
113
to
117
, and are conducted to the longitudinal folding unit I over the following paper guide rollers
131
to
135
through 90° in a vertical direction, which is offset by 90° in respect to the first vertical direction.
Thereafter, the longitudinally folded paper web strand
103
is conducted to the transverse folding unit H located on the lowest level C for further processing, after the longitudinally folded paper web strand
103
has passed over the pair of draw rollers
78
located upstream of the transverse folding unit H (FIG.
2
).
The two transverse folding units G, H are arranged on different horizontal levels O, N, wherein the level N with the transverse folding unit G is located above the level O. Here, the strand inlets E, F are each offset and distant from each other at a distance p.
In this case the delivery belts for the printed products are pointing in the same direction. Because of this it is possible that both transverse folding devices G, H can be operated separately or, when one of the transverse folding devices G or H fails, its production can be taken over by the other transverse folding device.
