DE2709767A1 - METHOD AND DEVICE FOR MANUFACTURING A SELF-COPYING MULTI-LAYER PAPER PRODUCT - Google Patents

Description

description

The invention relates to a method for producing a self-copying multilayer paper product or the like and a device for performing the method.

Usually, self-copying multilayer paper products or the like are produced in such a way that first the Paper web is coated with a head layer, whereupon the web is cut into narrow web sections and wound up. After this process, the rolls in question are used for printing, for laying the web sections on top of one another and for other possible handling, all of which can possibly be done in the same machine. A disadvantage of the manufacturing process described is that, starting from the printing phase, it is necessary to handle several short narrow rolls, which is what the manufacture slows down and increases the price of the end product. It is also possible that the small rolls, which are from temporary storage for printing and for treatment after Print, are sections of different webs that may have different paper quality characteristics resulting from, for example different pulp composition, the fluctuation of the basis weight and different fiber orientation. The influence of environmental factors and their changes conversely, has a different influence on different paper qualities, which means, for example, the shrinkage, which caused by the humidity of the environment, is of different sizes. Consequently, the quality of the products that comes out

stacked web sections are made of different paper webs and which are intended to be used, for example, as multilayer infinite forms, less caused by the seaming, so that the result can be such that when filling out the form the text in different places in the various Layers of the form come, whereby the clarity and legibility of the form is considerably reduced. Even a partial relocation of the sprocket holes which are normally used in the multi-layer Unendlichformularen ^e in question standing way is even more detrimental. This leads to frequent disruptions in the transport of the form.

It is an object of the invention to overcome the above-mentioned disadvantages in the production of self-copying multilayer paper products to eliminate and to create a method and a device for performing the method with which simplifies the manufacture of the product in question and accelerated and the quality of the end product is significantly improved.

To solve this problem, the method according to the invention is proposed that is characterized in that first the printing and the application of a copy layer on a wide paper tape is provided, in this or in reverse Sequence, and then a final treatment is carried out, which is the slitting of the tape and then placing the cut ribbon sections one on top of the other and other necessary treatments to produce the desired product.

This makes it possible to significantly simplify the manufacture of a product in question and to accelerate decisively, as it is no longer necessary to handle a large number of small, narrow rolls separately, whereby the effort can be reduced.

The paper quality of the different layers of the product no longer deviate significantly from one another, since all layers have been removed from the same paper web. Therefore, the environmental factors have basically the same influence on everyone Layers of the product, which improves the quality of the multi-layer product in question.

When applying the coating, it is advantageous that, if necessary, only part of the surface of the paper web and / or both sides of the paper web can be coated. Especially in the production of multi-layer infinite forms the treatment includes perforating the web and folding it in a zigzag manner. In this context, the web can also be used in are advantageously provided with transport holes for possible subsequent mechanical feeding of the infinite form. If set forms are produced, the various layers of the multilayer web must be appropriately connected in some way Place to be connected together, for example by gluing, and the web must be cut into sheets of suitable size will. The appropriate sequence and execution of these treatments, known per se, have been chosen to reflect the current one To adapt the situation in an extremely advantageous manner. For example, another treatment is winding of a manufactured multilayer tape is possible, and then the other final treatments are carried out at a later stage. In addition, individual possible combinations of these different treatments are also possible.

The production of the copy layer can be accelerated considerably if it is separated in a rapid manner Maeahine is carried out, after which the other treatments as described above are carried out in another machine will.

When using the diverter bar, the cut tape strips can easily be placed one on top of the other.

The deflection rods can also be arranged so that of the same paper tape two or more different groups of multilayer tape strips are formed, and the necessary Treatment is carried out separately on each group, so that several end products are obtained from one machine at the same time can be.

In the following, the application of the method for the production of a multi-ply infinite form is illustrated by an example of a device with reference to the accompanying drawing, which is a schematic perspective view represents the said device.

In the drawing, the numeral 1 denotes a paper tape passing through the coating stations 2a and 2b to the printing station 3 of the tape runs and from there to a station 4 for longitudinal cutting, whereupon the individual tape sections 5 with the help of deflection rods 6 are arranged one above the other in order to form two groups in the station 7. The tape sections can be combined so that they form one or, alternatively, more than two groups, so that a corresponding number of Multi-ply infinite forms is produced. After that will be the multilayer tapes produced, for example, perforated and folded in a zigzag fashion, which takes place in station 8. The same station can also punch the transport holes, if this is desired to be carried out, which is not shown in detail in the drawing. The finished forms will be transported on by conveyor belts 9, for example to be stored.

In the claims, the description and in the drawing disclosed features of the invention can be essential both individually and in any combination with one another for the implementation of the invention in its various embodiments.
