Definitions

  • the invention relates to a device for roughening a book block spine formed from compressed printed sheets according to the preamble of patent claim 1.
  • abrasives formed from carbides are used.
  • Carborundum coverings are used according to "Perfect Binding Technology", Alfred Furler, including a plate rotating around a vertical axis over which the book blocks are guided.
  • the resulting sanding dust clogs the free spaces of the carborundum coverings between the abrasive grain and there is a tendency to close the roughening tool, which is also transferred to the sheet edges.
  • the object of the invention is therefore to provide a device for roughening back-trimmed book blocks, with which paper fibers are exposed on the sheet edges or. Fillers can be lifted out in order to optimize the surface of the book block spine to be connected with the adhesive.
  • this object is achieved according to the characterizing part of patent claim 1.
  • a more effective roughening effect on the book block spine can be achieved than, for example, by the method and the device according to WO 91/06435.
  • the angle of attack ⁇ must be observed accordingly, taking into account the diameter of the roughening tool. Due to the deeper roughening action, the sheet edges laid laterally by the leading processing edges are returned to their original position and slightly fanned out, which further promotes the adhesive bond.
  • the processing edges of the roughening tool are advantageously arranged on the circumference of a circular holder, as a result of which a regular distribution of the markings on the spine of the book block can arise.
  • Suitable processing edges have been found to be cutting elements which, through an achievable cutting effect, permit gentle treatment of the sheet edges when paper fibers are exposed and / or fillers are excavated.
  • An optimization of the surface of the book block spine can be achieved if the peripheral speed of the processing edges is selected in coordination with the speed of travel of a book block so that the circular markings overlap.
  • FIG. 1 and 2 illustrate a device 1 for roughening the back of the book block of a book block 3 clamped in a clamp 2 of a non-visible perfect binder.
  • the direction of arrow F in FIG. 1 indicates the transport direction of the book block 3 passing a roughening tool 4 of a processing station of the perfect binder.
  • the folds of the printed sheets were previously removed by trimming or milling in the upstream processing station on the display 5 of the book block formed in the clamping pliers 2 from compressed individual printed sheets.
  • the pulling book block spines are formed to optimize the adhesive connection with a rough surface in order to expose paper fibers on the sheet edges of the printed sheets. Lift fillers out of the sheet edge.
  • the roughening tool 4 connected to the drive shaft 6 of a motor 7 consists of a disk-like or. circular holder 8, in the circumferential region of which projecting processing edges 9 are arranged on the end face.
  • Arrow R in FIG. 2 indicates one of the two possible directions of rotation.
  • the protruding processing edges 9 lie in a cutting plane which forms a flat angle of attack ⁇ with the processing plane on the spine of the book lock, such that the roughening tool protrudes from the spine of the book block on both sides 4 formed machining sections of a circle have opposite markings of different machining depths on the axis of rotation.
  • the subsequent processing or Marking section the greater depth in the spine of the book block than the previous one. That is to say that the angle lying in the plane formed from the axis of rotation of the roughening tool 4 and the direction of travel F of the book block 3, formed from the unroughened back section and the axis of rotation of the roughening tool, is more than 90 °.
  • the processing edges 9 designed as cutting elements can also be fastened to the front side of the holder 8 facing the back of the book block.
  • the processing depth of the roughening tool 4 is a maximum of 1 mm.
  • the tightness of the markings on the back of the book block can be selected by coordinating the peripheral speed and / or the number of processing edges with the speed of travel of a book block.
  • 1 and 2 furthermore show the possible combination of the roughening tool 4 with an annular brush 12 arranged concentrically outside of it, which subsequently removes dust and chips from the roughened surface.
  • the free bristle ends of the ring brush 12 driven in the same or opposite directions about the axis of rotation of the roughening tool 4 reach the bottom of the markings 10, 11.
