Definitions

  • the present invention relates to a method for the production of bound printed products, by adhesive-proof joining in each case an envelope with a book block according to the preamble of claim 1 and a device for carrying out the method according to the preamble of claim 4.
  • gathered sheets are bonded to a booklet block by applying an adhesive to the processed block spine.
  • An envelope grooved along the back edges is glued to the back of the block, with the envelope initially being pressed against the block spine and then laterally in the region near the back by means of press rails.
  • the cover caps are bent around the block back edges.
  • the paper, cardboard or cardboard material When the envelopes are creased, the paper, cardboard or cardboard material is deformed by compaction and / or displacement into a bead-like line, whereby the bending stiffness of the cover sheet is reduced and a hinge-like bending point forms in the sheet.
  • the grooves are often rotated, with one or more creasing knives and associated creasing matrices being arranged on counter-rotating, parallel creasing shafts.
  • the creasing knives and associated creasing matrices For transporting and guiding the sheets conveyor rollers are arranged on the creasing shafts adjacent to the creasing tools, which clamp the sheet in an effective manner.
  • Envelopes with a full-surface finish or with film lamination are not suitable for such treatment with liquid as it remains on the surface and does not penetrate the material to soften it.
  • the densification and / or displacement of the cover material achieved in the case of multi-layered, in particular foil-laminated envelopes can lead to undesired changes in the optical properties of the cover surfaces due to stretching or damage or else to delamination, the detachment of the layers from one another.
  • the object of the invention is to provide a method of the type mentioned and a device for its implementation, which are exempt from the disadvantages listed.
  • the invention achieves the object by a method having the features of patent claim 1 and by a device having the features of claim 4.
  • Advantageous developments of the invention are characterized by the features specified in the subclaims.
  • the bending lines are prepared in the envelope by grooves and thus reduces the flexural rigidity by removing material.
  • the influence of the paper direction respectively.
  • Fiber orientation in the cover sheet on the bending stiffness and restoring forces very limited, so that both in the transverse and in the longitudinal direction printed envelopes can be used in the same way.
  • joining or pressing into the groove penetrating adhesive additionally stabilizes the mold produced during pressing, whereby the durability of the product can be improved.
  • a groove inline with the joining since in this way additional acting on the grooved and thus weakened envelope processes such as stacking, storage, separation can be avoided.
  • the grooves can take place during the separation of the cover sheets or closing to the separation during the transport of the separation for joining with the book block.
  • the envelope to be used moves along a stationarily arranged groove tool relative to the grooving process.
  • a supply device is proposed with a magazine for storing a plurality of envelopes, a separating device for removing individual envelopes from this magazine and a transport device which supplies a stream of individually successive envelopes a joining device, such as the cover feeder of a perfect binder, which a groove device with knives for cutting grooves in the envelopes.
  • the groove device is arranged in the region of the transport path which feeds the envelopes of the joining device. This ensures good accessibility and visibility.
  • existing perfect binder can be retrofitted with little effort with such arranged groove device cost.
  • the groove device is arranged in the region of the separating device, as a result of which a particularly compact design can be achieved.
  • the device comprises a support device which supports the material to be cut during grooving against the knives, so that it can not escape with respect to the grooving knife and a uniform groove geometry, in particular cutting depth is reached.
  • the support device has a surface arranged opposite the knives, which surface supports the cover in the area of the groove knives.
  • this supporting surface is designed to be convex facing the knives.
  • an inlet mouth is formed between the groove knives on the one hand and the supporting surface on the other hand and on the other hand generates a rigid support surface even with low material use.
  • an over the camber exciting envelope during the Grooving process is stiffened and additionally secured against unintentional shifting or twisting.
  • a rotatable drum whose lateral surface forms this support surface.
  • the freely rotatable or driven drum leads to a roll on the envelope and avoids slipping and thus damage to the visible surfaces of envelope and unintentional movements due to areas of different friction such as partially applied paint.
  • this singling drum forms the support surface for the grooves. In this way can be dispensed with additional support means while retaining their function, whereby the construction can be kept compact and inexpensive.
  • the groove device comprises a hold-down device with at least one hold-down element, which holds the envelope in the region of the groove knife on the support surface.
  • the hold-down device ensures that the cutting depth remains constant over the entire height of the envelope. A lifting of the material to be cut when entering and leaving the blades and thus a locally greater cutting depth up to the severance is thus reliably avoided, in particular in the case of a convex support surface.
  • each hold-down element is designed as a roller or revolving belt.
  • At least one knife of the groove device is connected to a first feed device which determines the knife transversely to the groove and thus the position of the groove. So can easily the location of the hinge and the Width of the back area to be matched to the thickness of the associated book block.
  • this feed device preferably comprises a spindle drive.
  • the groove device comprises a second feed device which positions the knife perpendicular to the transport plane of the envelope to the cutting depth, respectively. adjust the residual cross section to adjust the mobility and stability of the hinge created by the grooves.
  • grooving is a machining process. Therefore, preferably all the same groove generating knife of the groove device are arranged on a common tool carrier, which has a channel adjoining the blades for discharging the chips. In a particularly advantageous design, this chip channel passes at its end facing away from the knives into a connection, which can be connected to a chip suction.
