The stream mixing device (01) has at least one former (02,03), at least one slitter (07,08) and at least two guide paths upon each of which a part stream (27,28) of longitudinally slitted part sheets of the stream is guided and which then combines into a main stream (29) at the outlet of the stream mixing device. On one of the guide paths a stapler (17) is located for the stapling of the part stream guided on this guide path. The stream mixing machine has at least one second former and a guide path for the guiding of an additional stream or part stream from the second former to the outlet. An independent claim is included for a method of mixing of streams of sheet material.

Description

The invention relates to a strand mixing device with at least two formers according to the preamble of claim 1.

The invention relates to a strand mixing device which can be used in newspaper printing between a printing machine and a transverse folding apparatus in order to bring a plurality of printed paper webs into a desired order for the finished printed product. In particular, the invention relates to a strand mixing device which is suitable for printed products in tabloid format.

DE 43 26 855 A1 discloses a strand mixing device with a former and two guide paths, on each of which a longitudinally cut part web is guided, wherein one of the part webs provided on its way with glue and then glued to the other part web. In another embodiment, two strands run over two formers, wherein one of the strands is glued by a stapler and the other strand in the manner mentioned, before they are both taken together to form a main strand.

From DE 43 44 362 A1 a strand mixing device with at least one former is known, wherein the strand leaving the former is optionally feasible around one or the other side of an underlying further former.

In DE 41 28 797A1 a funnel construction with several, arranged in different hopper levels formers is known. Strands folded by means of an overhead hopper can optionally down on one side or the other of an underlying former to a downstream folder be guided.

The invention has for its object to provide a strand mixing device with at least two formers.

The object is achieved by the features of claim 1.

The advantages that can be achieved with the invention are in particular that the strand mixing device allows the production of multi-layer products, in particular tabloid products, wherein at least one layer of the product is tacked.

Another advantage is that the strand mixing device manages without turning bars.

This reduces the cost of the device. In addition, the collection of material webs to be processed into the device before their commissioning is easy and quick to carry out. Eliminating turning also reduces the susceptibility of the line mixing device to breakdowns.

In this case, the strand mixing device may have at least one second former and a guide path for guiding a second sub-string from the second former to the output. With such a device, a sub-strand of the slit cut by the slitter can be mixed with the second sub-strand from the second former to a first book, while the other sub-strand of the cut by the slitter strand is stapled and gives a second book.

Preferably, a folder is connected to the output of the strand mixing device. With the folder, tabloid products can be made from the strand emerging from the strand mixing device.

Embodiments of the invention are illustrated in the drawings and will be described in more detail below.

Product examples a) to m) for the above-mentioned embodiments.

A strand mixing device 01 shown in Figure 1 comprises two formers 02; 03, guide rollers 04; 06; 18, two slitter 07; 08, pulleys 09; 11; 12; 13; 14; 16, two draw rollers 05; 10 and a stapler 17. To the strand mixing device 01 a folder 19 is connected, which has a cylinder 21, z. B. cutting cylinder 21, a cylinder 22, z. B. Schneidnut-, Punktur- and folding blade 22 and a cylinder 23, z. B. jaw cylinder 23 includes.

Through the former 03, a strand 24 is pulled in the direction of the arrow. The strand 24 is a plurality of parallel running printed paper webs 24 that are processed together into tabloid products.

During the passage through the former 03, the side by side on the former 03 running, longitudinally cut partial webs are brought together. Subsequent to the former 03, the folded strand 24, in this case strand 24 having successive partial webs, passes through guide rollers 06 and opens into the draw roller 05; 10 or Zugwalzengruppe 05; 10. The strand 24 is thus after passing through the former 03 from a double number of parallel paper webs 24, but which have a smaller width than the paper webs 24 before opening into the former 03. About the pulleys 14; 16, the strand 24 is guided to the guide rollers 18 and leaves over this the strand mixing 01.

Accordingly, a strand 26 is introduced into the former 02, which also consists of a plurality of parallel-running paper webs after longitudinal cutting and successive feeding. This strand 26 may, for. B. may be obtained together with the strand 24 by longitudinal cutting a double-width, printed in a printing machine strand before entering the strand mixing device 01.

In the former 02, the partial webs of the strand 26 are brought to each other and after leaving the former 02 on the guide rollers 04, the tension rollers 10; 05 supplied. The strand 26 is after leaving the draw roller 10; 05 of the guide roller 09, where he in contrast to the strand 24 in two sub-strands 27; 28, z. B. paper webs 27; 28 is split.

The sub-strand 28 is guided by the deflection roller 09 via the deflection roller 11 to the guide roller 18, ie to the output of the strand mixing device 01. Here he unites with the strand 24. Since the strands or partial strands 24; 27; 28 are guided towards each other in the region of the guide rollers 18, the location of the merging in the region of the guide rollers 18 is referred to here as the output, although it may also be located further downstream in terms of construction.

The sub-strand 27, however, runs from the guide roller 09 to the stapler 17. The stapler 17 staples the sub-strand 27 forming webs 27 - even before he enters the folder 19 - each along a line between two sides of the printed image generated thereon, at the later upon passage of the strand 27 through the folder 19, a transverse fold will be created. After leaving the stapler 17 is now composed of paper webs 27 stitched existing sub-strand 27 on the pulleys 12; 13 also leads to the guide roller 18 and unites there with both the sub-strand 28 and the strand 24. Thus, leaving the output of the strand mixing device 01 forming guide rollers 18 leaves a main strand 29, resulting from the unstapled paper webs of the strand 24, the unwoven paper webs 28 of the sub-strand 28 and the stitched paper webs 27 of the sub-string 27 composed.

This main strand 29 runs between the cutting cylinder 21 and the Schneidnut-, Punktur- and folding blade 22 of the folder 19 a. At the Schneidnut-, Punktur- and folding blade 22, a jaw cylinder 23 connects. Between the cylinders 21; 22 of the folder 19, the main strand 29 is cut in a known manner into individual products, which are then between the cylinders 22; 23 are cross-folded. The tabloid products made with the strand mixing device 01 shown have an outer non-stapled layer and an inner stapled layer.

Since the paper webs 26 of the strand 26 can be arbitrarily distributed to the partial strands 27, 28 on the deflection roller 09 and a paper web 26 corresponds in each case to four sides of the finished printed product, the handling of the stapled position in sections of four pages is arbitrary.

The strand mixing device 01 is not limited to the illustrated specific embodiment. Thus, it is possible, for example, the strand mixing device 01 to such modify that the stapler 17, instead of being arranged in the guide path of the sub-string 27, in the guide path of the sub-strand 28 is arranged. Then the paper webs forming the sub-strand 28 are stitched together at predetermined locations by the stapler 17, while the paper webs 27 forming the sub-strand 27 remain unstacked. After merging the partial strands 27; 28 with the strand 24 to the main strand 29 at the exit of the strand mixing device 01 at the guide rollers 18 and after passing through the folder 19 are produced with this alternative embodiment of the strand mixing device 01 tabloid products, which have three layers, with an outer and an inner layer are untied while a layer located between these two layers is stapled.

Of course, the strand 26 could also be complete, possibly together with branched off from the strand 24 paper webs, are guided by the stapler 17 when the stapled position a greater extent than desired for the unstapled.

Depending on the width of the strand mixing device 01 upstream printing machine, the strand mixing device 01 may also have more than two formers, then the guided through the stapler 17 sub-strand may be part of a resulting from one of the former longitudinally cut strand or even this strand completely and additionally paper webs may comprise a strand originating from an adjacent former.

In another embodiment of the or are the slitter 07; 08 not in front of the former 02; 03, but after the former 02; 03 arranged. In this case, the folded strand 26 after the former 02; 03 cut open at the seam back.

In an embodiment shown in FIG. 2, at least two strand guides of sub-strands 27 and 28 are associated with a former 02 and the strand 26 formed thereby. The strand 26 is for this before (or after the former 02 as above) along cut and then split on the strand guides of the partial strands 27 and 28. At least one of the strand guides, but advantageously both, in this case has on its way to a stapler 17. One or both of the partial strands 27; 28 may or may be stapled before they are combined again to form a product and further processed in the folder 19.

As indicated by dashed lines, a third sub-strand 31 can be led out of the strand 26, and stapled by a possibly present stapler 17, before this is again taken to product together. Likewise dashed is a strand guide, wherein a partial strand 32, for example, without deflection and / or without stapling straight down to the entrance into the folder 19 is performed.

A particular advantage lies in the embodiment of FIG. 2 in that for several separately stapled or z.T. unstacked "books" of a product the number of formers 02; 03 is significantly reduced. For example, with similar product variability, an additional hopper (balloon hopper) otherwise located above the former 02 can be saved. As a result, significant construction costs and height can be saved.

In a third embodiment (Figure 3), the two strands 27; 28 from the former 02 to both sides of a z. B. underlying Former 03 via pulleys 09; 09 'led. On one or both strand guides of the strands 27; 28 may be arranged as in the former examples, a stapler 17 (shown in phantom). The two strands 27; 28 are performed in front of the folder 19 with the strand 24 from the lower former 03, the latter comes to rest between the first two. In an advantageous embodiment, a stapling device 17 'can be arranged in the strand guide of the strand 24 in addition to or instead of the stapling device or the stapling devices 17. In a distinguished by high flexibility execution has both the strand guide of the strand 24, as well at least one of the strand guides of the webs 27 bypassing the former on both sides; 28, a stapler 17; 17 'up. If it should be possible to produce more variable, the strand guides of the three strands 24; 27; 28 each have a stapler 17; 17 'up.

In all three embodiments, by way of example in Fig. 3 indicated additional bypass strand guides 33; Be provided 34, by means of which a present on a strand guide stapler 17; 17 'with a part of -. B. again divided - strands 24; 27; 28 or with the entire strand 24; 27; 28 is feasible without stitching. In Fig. 3 are only two bypass strand guides 33; 34 indicated without dashed pulleys etc. indicated by dashed lines. However, these are in development on individual, several or all strands 24; 27; 28 optionally transfer from the three embodiments.

In a fourth embodiment (Figure 4) are two formers 02; 03, each with a slitter 07; 08 each a stapler 17; 17 'in the guide path from the respective former 02; 03 assigned to the output of the strand mixing device 01. The strand mixing device 01 in this case has pulleys 09; 14; 36; 37, via which a partial strand 28 or the entire strand 26 of a former 02 by the second former 03 associated stapler 17 'together with a sub-strand 27' or the entire strand 24 of this second former 03; 02 is guided feasible or in an advantageous embodiment. In a superstructure, not shown, therefore, must not already be determined by turning of partial webs correct for stapling funnel casserole, but partial web can after passing through the former 02; 03 nor the other to stapling sub-strand 27 'or strand 24 are added. It can also all partial webs, ie both folded and cut strands 24; 26 via one of the staplers 17 '; 17 to be processed into a product. It is also possible that a sub-strand 28 is stapled together with a strand 24 or sub-strand 27 'of the other former 03, while the remaining sub-strand 27 of the first former 11 passes through the associated stapler 17 without stapling (ie, stapler not in use or out of service). The arrangement with the mentioned reference numbers is to be applied symmetrically to the reverse guide.

Through said guide paths on the two staplers 17; 17 ', a main strand 29 is obtainable at the exit in a first mode having a part with one or more non-stitched layers (eg, stapled stapler 17, 17') and a part with several stapled layers (Figure 5 a), shown from inside to outside). In a second mode of operation (FIG. 5 b)), the main strand is formed by two parts each having a plurality of layers stitched together, wherein the number of layers between the two parts is determined by o. G. Overpass can be variable.

Advantageously, the strand mixing device 01 further deflection rollers 11; 16, via which a sub-string 28 as required; 28 'of the one and / or the other former 02; 03 without passing through one of the staplers 17; 17 'along a corresponding guide path between the two staplers 17; 17 'is passed through the output or are.

This allows the o. G. Modify operations and resulting products on the main strand 29 to the effect that in addition to the above sequences in the parts between the two parts already mentioned - in particular the two stapled parts of the second mode of operation - additionally introduced a part with one or more non-stitched layers in a third mode is (Fig. 5 c)). Number and origin of the position (s) of this latter part is variable, they can / from one, the other or both Former 02; 03 come.

Even more flexible in the product to be produced is the strand mixing device 01 with further deflection rollers 09; 09 ';10; 10 ';11; 12 executed, via which a sub-string 27; 28; 27 '; 28 'at least one of the former 02; 03 without passing through one of the staplers 17; 17 'on an outer side of the strand mixing device 01 around the two staplers 17; 17 'can be carried around to the exit. In Fig. 4 is for each of the two formers 02; 03 such a subsequent as a bypass strand guide 33; 34 designated guide provided. This allows in addition to the first two modes of operation and the third mode of operation, that the respective sequence of parts on the one and / or the other strand outside of the main strand 29 now obtained can be added or added another part with one or more non-stitched layers , For example, in a fourth mode of operation, a sequence of one untied portion, one stitched portion, one untied portion, and a second stitched portion (FIG. 5 d) is shown, and in a fifth mode of operation, an additional non-stitched portion (FIG. 5 e). possible or produced. In a sixth mode of operation, a sequence of a non-stapled portion, a stapled portion and a second stapled portion (Fig. 5f)), and in a seventh mode thereof, an additional non-stapled portion (Fig. 5g) may be achieved.

The said pulleys 09; 11; 12; 13; 14; 16; 36; 37 are as rollers 09; 11; 12; 13; 14; 16, in particular as driven only by friction rollers 09; 11; 12; 13; 14; 16 executed and serve the leadership.

In the folder 19, the main strand 29 is cut transversely into product sections and the product sections thus obtained, for example, transversely folded.

The achievable for the above-mentioned operations cross-folded products are exemplified in Fig. 5 a) to g). The number of layers per part (stapled or unstapled) is chosen here only as an example. However, the number of layers in the part may be lower or higher than shown. Different parts may have different number of layers. In particular, for unstapled parts, the number of layers can also be 1. A stitch is indicated by a line connecting the layers in the region of the fold back.

In Fig. 5 are u. a. also shown by various modes of operation of the device of FIG. 1 achievable products. Fig. 5 a) shows a product, wherein z. B. a transfer of a not provided for stapling partial strand 28 takes place.

Also in Fig. 5 are u. a. (but not exhaustive) which can be removed by various modes of operation of the device of FIG. 2. For example, with only the solid strands 27; 28 the product according to FIG. 5 a) (a stapling device turned off) and FIG. 5 b) can be achieved. Without consideration of a guidance of the sub-strand 31 - as provided in a basic version of the embodiment according to FIG. 2 - but with the possibility for the sub-strand 32, FIG. 5 c) can be produced. With the sub-strand 31 (without the guidance of a sub-strand 32) is also available left stapler 17, parked or absent middle and employed right stapler 17 also Fig. 5 c), and additionally employed middle stapler 17 Fig. 5 j) achievable. However, if the left stapler 17 instead does not exist or is turned off, then Fig. 5 m) can be realized. Fig. 5 h) shows a possible, by all drawn guides and the three (salaried) staplers 17 product produced.

In addition to the products mentioned in the description part of FIG. 4 (FIGS. 5 a) to 5 g)), but to be transferred to operating situations with optionally parked or not provided staplers 17; 17 'or used or unused bypasses 33; 34) is with the apparatus of Figure 3, taking into account the bypass 33 and three staplers 17; 17 'a product according to Fig. 5 i), and without bypass 33, but with bypass 34, the inversion of the product of Fig. 5 h). Assign all three solid strands or partial strands 24; 27; 28, a stapler 17; 17 ', so is without further bypass 33; 34 the product according to FIG. 5 j) can be produced from three parts. If only a stapling device 17 'is provided for the strand 24 (or alternatively only this one of two or three stapling devices 17, 17' is employed, the result is a product according to FIG.

However, the order in the representation from the inside to the outside are reversible either by appropriate guidance by the strand mixing device 01 or by a change of the folding apparatus 19.

It is particularly advantageous that the products mentioned are usually at least largely without, in particular without previous turning of partial webs in a superstructure before the formers 02; 03 are produced. The one or the other strand or sub-strand 24; 27; 28 to be assigned partial webs are transferred in the strand mixing device 01 to the desired location.
