FR2476545A1 - PROCESS FOR MANUFACTURING BROOCHED WAFERS IN ROTARY PRINTING MACHINES - Google Patents

Abstract

The invention relates to a method of producing stitched brochures with simultaneous feeding of envelopes and/or inserts in web-fed rotary printing machines. The object of the invention is the development of a technique for brochure production which allows brochures to be produced in one production line with envelopes of any desired colouring, different thickness, different dimensions, and with inserts of different sizes. The object is achieved in that preprinted blanks of paper, cardboard or plastic are fed from one or more sheet feeders to the printing carrier web, to partial sections or to portions of the printing carrier web in the form of envelopes and/or inserts within one production line.

Description

The invention relates to a method for manufacturing paper plates in rotary printing machines by simultaneously feeding covers and / or supplements.
We know from Swiss Patent 414 689 a process for manufacturing by assembly of printing products.

In this process, blankets and / or supplements are fed into the machine in the form of preprinted strips. These tapes are stored on reels, which are stored until needed.

For the production of the pre-printed roll with covers or supplements, a functional rotary printing machine of a determined format is required, with a variation as great as possible in coloring, with a coating device and a device for drying the printed tape before rewinding it. In addition, the machine must be suitable for a large assortment of cardboard. When the pre-printed roll is fed with the covers of the supplements by the printing substance in the rotary printing machine, the problem arises. sorting of smudged products, feed with precise identification, gaps between covers for total and partial production, in any case continuous feed when changing the roll
The variability of formats is limited.

 Processes are also known by which the assembly of pre-printed notebooks and covers is carried out in appropriate technical installations for this purpose continuous shaping of the binding; such as broaching and cutting, follows directly.

A very wide advantageous sequence of the various treatment stations is not possible because of the different working speeds, reliability among others. For this reason, we need to have technical means of reception and storage as well as transport and storage capacities.
The object of the invention is to create a process for rationally manufacturing brocaded wafers with supplements.

The objective of the invention is the development of a technology for the production of wafers, which makes it possible to manufacture in a wafer production line with covers of any color, of different thicknesses, of different dimensions, as well only with supplements of different sizes.

The invention relates, to solve this technical problem, a method which is characterized in that the pre-printed blanks are fed with paper, cardboard or plast matte father qûe, from one or more automatic feeders on a strip of printing substance, to partial cords either partially or in sections of the printing strip, in the form of covers and / or supplements within a production line.

 For a minimum mechanical expense, it is rational that the covers and / or supplements are stapled, folded and cut in common with the notebooks. As a basis from which to ensure a wide range of products, it is advantageous to proceed by feeding the covers into the folder in accordance with the format of the notebooks and by being able to vary the dimensions of the supplements in relation to the covers. It is advisable that the covers are supplied with single or multiple use.

A pretreatment carried out rationally consists of the fact that the covers and / or supplements that are introduced are subjected, on the path of supply of the notebooks, to a pretreatment consisting according to the choice of coating, grooving, embossing, stamping or punch. Advantage in product quality is achieved advantageously by assembling the covers with their supplements in the form or by suitable material.

 Thanks to the process according to the invention of feeding blankets and / or supplements in the form of blanks from a stack on the printing substance in the rotary printing machine, it is possible to manufacture in a continuous technological production chain of paperback plates with blankets and / or supplements of very different kinds.

The invention will be better understood with the aid of the description below and the appended drawing representing an exemplary embodiment of the invention.

The single figure in this drawing is a schematic overview of the different distinct operating phases.

 The printed web 2 is continuously fed into a rotary printing machine 1, in a location which is well suited to the technological progress of the operations - for example after the turning bars 3, the folding shaper 4 and the transverse cutting member. 5 - the covers 6 and / or their supplements in the form of cut sheets, which are then separated by a feeder 7, from a stack 8.

During their feeding, these cut sheets are subjected to a preliminary treatment 17.

 The cut sheets can for example be treated with the notebooks printed in an assembly cylinder 9, a jaw folding cylinder 102 a broaching device for longitudinal sewing 11 and a third lengthwise folding 12 or else a broaching device for sewing transverse 13 and a third transverse folding 14, then they are brought into a common trimming apparatus 15 so as to constitute brochures therefrom and they are taken out by a common device 16.

 The advantages of the process according to the invention compared to known processes lie in the reduction in the expense of manual labor, the operations of inserting and removing products between the various treatment stations being eliminated. We also no longer need the storage capacity necessary for this purpose. Thanks to the integration of grouped groups in the rotary printing machine, the production area required is reduced. The production circuit is shortened, so that adaptation to current production requirements is easier.

 The method also provides the advantage of variable and economical treatment of the cut sheets, on sheet printing machines, with any color and format. Sorting spotted products is therefore not a problem. We obtain a very wide assortment of material for the cut sheets. The introduction of these into the rotary printing machine can be carried out continuously. A pre-selection of the different intervals to be observed when feeding the cut sheets is done thanks to an appropriate timing of the feeder. There are no tracking problems.
