Definitions

  • the invention relates to a method for producing printed products, in particular softcover books, with which both the envelope and the contents of the printed product can be produced simultaneously in one and the same printing line with one and the same printer.
  • the envelopes were printed, typically in the form of printed Individual sheets.
  • Another intermediate product was a loose envelope.
  • the signature stack or book block was first processed on the back, i. in particular milled or roughened and then provided with adhesive. Thereafter, the envelope was fed and firmly bonded to the signature stack (or book block).
  • devices are also required which check whether the two merged partial products actually belong together (this is the case in particular in the case of personalized printed products in which a corresponding mix-up is to be ruled out, as for exam forms for students or at customer-specific bank data brochures, which are issued today especially in the private banking sector).
  • the printed product or the bound book is then trimmed to up to three pages.
  • EP 2 650 137 A2 discloses the preamble of claim 1.
  • a method for producing printed products, in particular softcover books, with an integrated envelope comprising at least the following steps: (a) printing on a paper web or of individually supplied paper sheets, preferably by means of digital printing; (b) optionally applying an adhesive coating to the paper web or sheets of paper; (c) single or multiple folding and cutting of the paper web into signatures (the cutting can be carried out before or after the folding, depending on the application) or one or more folds of the paper sheets into signatures; (d) optionally applying an adhesive coating to the signatures; (e) stacking the signatures into a signature stack having at least an uppermost and a lowermost signature; (f) unfolding the uppermost sheet of the uppermost signature or the lowermost sheet of the lowermost signature and applying an adhesive layer in at least the region of the unfolded sheet comprising at least the spine and / or an area of the signature stack adjacent to the spine (ie in the final printed product ); (g) transferring the unfolded and adhesive coated sheet around the spine of
  • the inventive method can be carried out inline without interrupting the process chain.
  • steps (f), (g) and (h) are performed off-line.
  • the cost advantages are obvious - in contrast to a conventional softcover printed product accounts for the Pre-production of the envelope, the binding process and the regularly complex control, whether envelope and content match - which in the negative case, moreover, requires a stop of the plant and / or a subsequent production.
  • the envelope and spine are simultaneously labeled or printed with the contents, ie the content is indicated both on the front and back as well as on the back.
  • Another positive aspect of the inventive method is that paper can be saved, as compared to the conventional binding process eliminates the milling and roughening of the paper. In addition, only one type of paper must be used according to the inventive method.
  • pruning of the printed product can be dispensed with on up to three pages.
  • the invention is basically used for the production of rather inexpensive printed products, which generally do not have to have a particularly long service life (for example, study books and other "disposable products", etc.).
  • a preferred embodiment of the present invention takes place before or during the stacking of the signatures of the adhesive application to the top and / or Bottom of the individual signatures.
  • an adhesive application takes place in the back region of the signature stack.
  • the adhesive can be applied in strips transversely or else over the full area over the back of the already completed signature stack (which remains correspondingly aligned). This solution is less time consuming than the bonding of each signature and also provides good stability of the stack. In addition, it gives the pile back a certain flexibility.
  • the adhesive layer is designed in the form of a (conventional) adhesive application or in the form of a double-sided adhesive tape.
  • a double-sided adhesive tape or tapes
  • the adhesive tape may also be, for example, a prefabricated adhesive strip, which is activated by the heat after the topmost or the lowermost signature sheet has been transferred around the stack.
  • prefabricated adhesive strips can in principle be used for all adhesive applications in connection with the method according to the invention.
  • the adhesive jobs are from Cold adhesives, hot adhesives or hotmelts (eg polyurethane adhesive) or formed from a combination of cold and hot adhesives.
  • hot adhesives or hotmelts eg polyurethane adhesive
  • bonding takes place immediately when the cover sheet is folded over or after heat transfer has taken place.
  • one or more grooves are introduced into the paper web sections or paper sheets (or signature sheets) provided as the uppermost or the lowest signature.
  • a grooving serves to facilitate the transfer of the respective cover sheet by a corresponding weakening of the paper.
  • the grooves are preferably arranged so that they correspond to the thickness of the printed product or softcover book. In other words, the (paper) surface between the preferably two parallel grooves forms the back of the printed product or softcover book.
  • the unfolded cover sheet is thus folded twice, ie each along the grooves (which define corresponding inflexible lines) when folded over about 90 °.
  • the creasing is usually done before the corresponding sheet (ie, either the sheet cut from the paper sheet or the sheet fed separately) is folded and, like the adhesive coating, can be dynamically and automatically adjusted for the desired thickness of the printed product.
  • a perforation or a trace of water droplets can basically be provided to weaken the paper.
  • the paper web sections or sheets of paper (or signature sheets) provided as the uppermost or the lowest signature are printed with a stability-increasing coating (i.e., preferably in step (a) of the process according to the invention).
  • a stability-increasing coating i.e., preferably in step (a) of the process according to the invention.
  • either the uppermost sheet of the uppermost signature or the lowermost sheet of the lowermost signature is formed with a length which is substantially longer than the length of the remaining signature sheets by the thickness of the spine of the printed product.
  • the cutting of the paper web or the feeding of the paper sheets must be carried out such that the paper web section or the sheet of paper, which is to form the uppermost or the lowest signature to the thickness of the product to be produced longer than the others web sections or paper sheets which form the content of the printed product.

  • a projection X which compensates for the resulting gap L.
  • the unfolded and adhesive-coated (cover) sheet is cut at its free end along the adhesive layer.
  • a preferred market practice is to cut off the cover sheet parallel to the spine (i.e., along the adhesive layer at its free end) prior to transfer. Obtained in this way a possibility of bonding analogous to a binding means KaylzelstMail.
  • the complete printed product can then be introduced as a (cheap) precursor, for example in a hardcover envelope (as a more expensive end product).
  • Fig. 1 a production line for printed products or softcover books according to the prior art is illustrated.
  • a corresponding paper web is first printed.
  • the paper web is then folded in a folding cross-cutting module 2 and separated into individual signatures 7.
  • a folding cross-cutting module 2 instead of a combined folding cross-cutting module 2 but also a separate folding module 2a and a separate cross cutter 2b can be used.
  • the isolated signatures 7 are stacked.
  • the envelopes for the subsequent printed product or softcover book are printed or produced (ie typically as printed single sheets).
  • the finished envelopes 4a are merged in a further step with the signature stacks (which are also referred to as book blocks) from the stacking station 3. This happens regularly in a binding station 5. Following the binding station 5, the bound products are fed to a trimming station, i. usually a three-side cutter 6.

  • the correspondingly printed signatures a are folded once in the longitudinal direction, ie around the line 11, and then cross-cut along the lines 12 (ie, the cutting is carried out after folding) and then stacked thereon.
