Abstract

A cover sheet (10) with a desired format height is separated from the cover web (4) after unwinding the cover web. The separated cover sheet is fed to the inner portion (2) of the printed product (14) before placing the cover sheet around the inner portion and connecting the cover sheet. An independent claim is also included for a producing apparatus for bound printed products.

Description

The present invention relates to a method and an apparatus for carrying out the method for applying an envelope in the production of glued or wire-stitched books, brochures, magazines or the like. Printed products, comprising an inner part consisting of a collection of folded sheets, layers and / or single sheets and the envelope, which is placed around the inner part and connected to this.

In an adhesive binder for making tapes, brochures, or magazines, collated sheets or signatures are conveyed into book block tongs of a transport system with a defined tag and joined to a book or booklet block by applying an adhesive to the processed block spine. A cover-applying and pressing device joins a grooved envelope to the book or booklet block, the envelope being pressed against the block spine and adjacent side portions during the continuous movement of the book or booklet block.

Saddle stitchers are used for the production of saddle-stitched magazines and magazines. Nesting folded sheets are joined together with an envelope from the outside to the inside through the back with wire clamps form-fitting. The envelope is previously fed via a Umschlagfalzanleger the folded sheet collection by the envelope folded and istooth stored on a folding sheet collection transporting collector chain.

Depending on the type of provision or stocking of the envelopes, there are cover feeders as a flat pile feeder, vertical sheet feeder or shed feeder. They all have in common that the envelopes must be loaded in batches by hand in the magazines or on the Schuppenanlegebänder. Skill and experience in dealing with large-scale envelopes are required for speedy and perfect loading. For perfect binders and saddle stitchers in the upper performance range, it is usually necessary to park a manpower alone for loading the cover feeder.

When unzipping the envelopes in the cover feeder can sometimes lead to false or double prints, a problem with specially executed envelopes, such as Envelopes with embraced flaps, pasted inserts, perforations or punches or envelopes formed of two, about a Fälzelstreifen flat-glued attachments, so-called Combined Endsheets, increasingly occurs and often has its cause in displaced or adherent envelopes. The elimination of such disorders and thus induced consequential disorders at other locations of the perfect binder or saddle stitcher is associated with not inconsiderable time and reduces the net performance of the adhesive binding book.

Another disadvantage is that the envelopes cut to the desired format on plan cutters can have dimensional and angular deviations which result in an inaccurate position of the envelope for the book block on the end product.

It is an object of the present invention to provide a method for applying an envelope in the production of taped or wire-stitched books, brochures, magazines or the like. Printed products comprising an interior consisting of a collection of signatures, plies and / or single sheets and an envelope, which is placed around the inner part and connected to this, and to propose an apparatus for carrying out the method, which allow a reliable and proper feeding of the envelopes to the inner parts and require little effort.

This is achieved by the invention in a surprisingly simple manner in that a roll of a wound transfer path is provided, that the transfer path is unrolled, and that a cover sheet is separated in the desired format height of the transfer path and the inner part for transferring and connecting is supplied. The single cover sheet is created only before merging with the inner part by separating from the transfer path. The process of separation is much more reliable and product gentle than the separation of the envelopes from a pile stock, with the result of significantly lower disturbances due to e.g. missing or double envelopes in the envelope feeder.

It eliminates the manual loading of magazines or Schuppenanlegebänder with stacks of difficult-to-use large envelopes. In addition, much more envelopes can be stored on a roll than in a stack, so that their handling and provision at the cover feeder simplify once again and a separate operator for the cover feeder is no longer necessary.

The cutting of the envelopes in the plan cutter is eliminated. The envelopes are made with high accuracy during the envelope feed in the perfect binder. The production, handling and temporary storage of the rolled-up transhipment track is also associated with reduced expenses.

According to a preferred embodiment of the method, the transfer web is printed after unwinding. In particular, simple, e.g. Solid envelopes can be produced quickly and cost-effectively with the desired content without the use of a separate printing press. In principle, however, the method also enables the immediate production of elaborately designed, color-printed envelopes on the perfect binder.

Preferred further developments of the method according to the invention with regard to additional processing results from the subclaims 3 to 7. They are characterized by the recognition that the further processing and finishing can be carried out much more reliably and gently on the endless transfer path than on a single cover sheet.

A preferred embodiment according to claim 8 provides that the so-called Combined Endsheets are separated immediately before their merging with the book block by Abrennen from a combined intent sheet web.

According to claim 9, the separation of the cover sheet takes place only immediately before contacting with the inner part. The severed cover sheets arrive over a relatively short conveyor line directly to the place of assembly.

Advantageously, the separated cover sheets are buffered in a magazine according to claim 10. The number of buffered cover sheet can be kept so low that a reliable separation of the cover sheet is still given in contrast to the magazines known from the prior art envelope feeder. Buffering enables continuous and uniform unwinding of the transfer path, regardless of potential performance fluctuations on the perfect binder or saddle stitcher.

Finally, claims 11 and 12 specify preferred applications of the method according to the invention in an adhesive binder or in a saddle stitcher.

In the apparatus for carrying out the method specified in claim 13, one of the Umschlaganlegevorrichtung upstream unwinding for unrolling a Umschlagbahn of a roll, and a cross cutter for separating a cover sheet provided by the transfer path. Abrolleinrichtungen and sheeters are known facilities in the paper web processing and have a high reliability due to their simple principles of action. Further device features emerge from the further dependent claims.

The figures each show a partial view of an adhesive binder 1, which has a transport system 16 with a plurality of in a closed, oval-shaped orbit continuously movable and drivingly interconnected book block pliers 17, with an import for feeding the folded book block 2 to the book block pliers 17 and with an export to run the bound booklets 14 or book block 15.

Along a first rectilinear conveying path of the transport system 16, means for back processing 18, back gluing 19 and side gluing 20 of the book block 2 are arranged. Along the second rectilinear conveyor line are an envelope feed 23 a, b, c or d and at least one Umschlaganpressvorrichtung 24, for pressing an envelope 10, 11, 12 or 13 on the glued book block spine of the book jack. 2

According to the invention, the envelope feed 23 a, b, c and d, respectively, have a unwinding device 30 for unwinding a transfer web 4, wherein the transfer web 4 is pulled off by a take-off roller pair 31 from the rewinding roller 3 accommodated in the unwinding device 30. Directly behind the take-off roller pair according to the invention is a cross cutter 35, for separating an envelope 10, 11, 12 or 13 from the transfer 4.

The separated envelope 10, 11, 12 or 13 is transferred to an envelope conveyor 21, consisting of two parallel juxtaposed conveyor belt 21 a with drivers 21 b, and transported by this up to a pressure roller 22, the envelope 10,11,12 or 13 presses on the book block back. Instead of the pressure roller 22, a pressure table can also be used. Immediately behind the pressure roller 22 is the Umschlaganpresseinrichtung 24, which presses the envelope 10, 11, 12 or 13 with rotating Andrückschienen from below and laterally to the book block back.

A first shown in Fig. 1 embodiment 23 a of the envelope feeder has in addition to the unwinding device 30, the pair of take-off rollers 31 and the cross cutter 35, a dancer roller system 32 and a grooving device 34 with rotary scoring tools 34 a and allows the provision and supply of simple, two - or quadruple grooved envelopes 10.

The creasing of the envelopes takes place on the quasi-endless transfer web 4, whereby a continuous transport of the transfer web 4 is given by the dancer roller system 32 regardless of potentially occurring power fluctuations on the perfect binder. The fact that individual envelopes are no longer run with their leading edge in the creasing tools, the grooves of the envelopes is gentle to the product and of high quality.

A second embodiment 23 b of the envelope feeder is shown in Fig. 2 and has next to the groove means 34, a print head 36 as a printing device, a Längsbeschnitteinrichtung 33 with rotary blades 33 a, a card adhesive 37 as Beilagenanklebeeinrichtung and a Fälzeleinrichtung 38. The envelope feeder 23b makes it possible to provide and supply envelopes 11 with inside fins 5 pasted in the back area and on the inside of an envelope side adhered advertising cards 6, for the production of e.g. Lay-flat booklets.

In the Fälzeleinrichtung 38, not shown, the Fälzelstreifen 5 is unwound from a Fälzelrolle 5 a, glued with a glue nozzle 38 a and glued onto the transfer track 4. The card adhesive 37, also not shown, removes the advertising card 6 a stack 6 a and places it, provided with a glue trace, in defined, the later envelope height corresponding distances on the transfer path 4 from.

With the Längsbeschnitteinrichtung 33, it is possible to provide provided in unit widths, neutral Umschlagsbahnen 4 to cut the width of each required for the brochure cover width. With the printing station 36, such a neutral transfer path 4 can be printed with content related to the paperboard to be produced.

To allow a continuous and uniform unwinding of the cover 4, regardless of potential performance variations on the perfect binder, the envelope feed 23 b is equipped with a buffer magazine 39, in which the separated from the cross cutter 36 envelopes 11 are discharged. The fact that only a limited number of envelopes 11 must be cached, the envelope stack has only a low stacking height and a low stacking load, so it does not come to displacements and / or adherence between the envelopes 11, the reliable separation of the envelopes 11 from the buffer magazine 39 would hinder.

In Fig. 3, a third embodiment 23 c of the envelope feed is shown. It allows the provision and supply of so-called Combined Endsheets 12, consisting of two mutually parallel and flat-glued with a Fälzelstreifen 5 Vorsatzblättern, for the production of rebated and with Vorsatzblättern provided book block 15th

The endpapers are unfolded unfolded as a double-width web in the unwinding device 30 and divided by means of a longitudinal divider 40 into two partial webs, which are folded over in the further course of the web with a web folding device 41 to intent sheet webs 7. With a arranged below the trajectory Fälzeleinrichtung 38, the two, at a defined distance from each other Vorsatzbogenbahnen 7 are glued flat to a combined Vorsatzbogenbahn 8, from which then combined with the cross cutter 35 Combined Endsheets 12 in the desired format height can be separated.

A fourth embodiment 23 d of the envelope feed is shown in FIG. 4. It has, in addition to the first, shown in Fig. 1 embodiment 23a a Klappenrill- and -einschlagvorrichtung 42 and allows the provision and supply of flap envelopes 13, in which the flap flaps are taken. The endless grooves of the flap folds and the folding over of the flap flaps on the endless transfer web 4 are particularly advantageous in this case.

The described embodiments of the invention relate to the envelope feed 23 a, b, c, d in an adhesive binder 1. It is expressly pointed out that the method according to the invention can also be used on saddle stitchers, with a simple groove device arranged in front of the cross cutter the Umschlrückückenfalz is created and the cover pages are foldable after the separation of the envelope down.
