Definitions

  • the invention relates to a device according to the preamble of claim 1.
  • a device is described for example in the patent specification GB-A-2 096 945.
  • the purpose of the book edge is to enlarge the surface of the sheet edge by making notches running transversely to the side or fold edges. This processing requires a great deal of effort and places considerable stress on a bookbinding system.
  • An unstable book block display leads to imprecise dimensional accuracy and has a quality-reducing effect on the product to be manufactured.
  • the stationary side supports previously used for the book block notice left behind harmful marks such as grazes or fuselages due to high frictional forces.
  • the support device had to be readjusted or replaced after a certain time due to wear.
  • rotating press rollers are used as counterholders on both sides of the book block display, which are able to support the book block display due to the approximately flush cutting plane.
  • the grooves in the guide run approximately parallel to the clamped book block spine, while the one groove is at Using a rotating notching tool also has the shape of a circular section.
  • the counterholder is expediently freely rotatable, but can also be driven at the speed of the book blocks.
  • the movement path is preferably designed as a groove in a guide plate set back relative to the cylindrical support surface.
  • the cylindrical support surface is designed as a protruding disk of a rotating body which is approximately perpendicular to the working plane.
  • the end edge of the counter-holder is designed to slide on the guide plate and if necessary a small distance is provided from the groove bottom.
  • the guide plate in the case of a one-piece design, is relatively thin due to the notching tool which dips into the groove and is therefore not particularly suitable for loading by the counter-holder, it is advantageous if the counter-holder is mounted on a shaft fixed on one side in a carrier.
  • the latter is preferably designed to be adjustable.
  • the bearing shaft is axially guided in the guide plate at the end opposite the fastening end.
  • the support forming the mounting of the bearing shaft is connected to the guide plate to form a simple, stable element.
  • the guide plate can be designed in several parts for the purpose of replacing wear parts.
  • a base plate and two base parts releasably connected to it are preferably provided, which can be replaced in a simple manner.
  • the skirting boards advantageously form the end of the guide plates facing the notice board.
  • FIG. 1 to 3 show a device 1 for a bookbinding machine for the production of books or brochures which are adhesively bonded to the back, in which the book blocks 2 have notches 4 on their backs 3 which run approximately transversely to the side or fold edges, primarily through Metal turning or milling tools 5 are generated.
  • the notch 7 on the underside of the two-part jig 6 of a book block 2 laterally abuts a counter-holder 8, which supports the notch 7 against the cutting force of the tool 5 and the gaping of the sheet edges.
  • the counter-holder 8 acting on the display 7 is equipped with a rotatable cylindrical support surface 9 which is frictionally connected to the display 7 but could also be driven at the same speed as the book blocks 2.
  • the drivable counter-holder 8 is arranged above a groove 10 which laterally surrounds the movement path of the notching tool 5, the latter being arranged in a guide plate 11 set back from the cylindrical support surface 9 relative to the book block, which, as shown, can also consist of several parts 12, 13, 14 is. If the guide plate is formed in one piece, a larger notch 7 is required to achieve the intended notch depth and a lateral reinforcement of the guide plate 11. In the embodiment shown, however, the guide plate 11 has a base plate 12 and base parts 13 and 14 fastened thereon, which are placed in a wedge-like manner on the base plate 12 and fastened by means of screw 15.
  • the two-part nature of the base plate 12 that results from the recess 16 along the movement path of the notching tool means that the base plate part 17 is fastened to a fixed adapter 18 connected to the stand of the bookbinding machine.
  • the latter can, for example, be attached to the support 20 which receives the bearing shaft 19 of the counter-holder 8 and which in turn is connected to the machine stand. If, as can be seen in FIGS. 1 and 2, a notch tool 5 rotating parallel to the book block spine 3 is used, then the recess 16 for the movement path of the rotating notch tool 5, the axis of rotation of which is arranged approximately perpendicular to the book block spine, runs according to a circular section according to FIGS dashed lines 30 in FIG. 2. This is one of the reasons why the guide plate 11 has multiple parts. When using milling cutters that are moved against the back of the book block from below, it is advantageous if they are driven at the speed of travel of the book block, that is to say during the milling process, and are driven back to their initial position.
  • the rotating counter-holder 8 has a circular cross-sectional shape stepped like a pyramid and is provided on its circumference with a cylindrical or disk-like support surface 9.
  • the two front ends of the counter-holder 8 are formed with neck-like projections 21, 22 which, when immersed in an opposite depression, form a labyrinth-like seal against dust or chips.
  • the bearing shaft 19 which is perpendicular to the spine of the book block 3, is axially penetrated by a screw 23 fixed in the carrier 20 and anchored in it on one side, whereas the other end of the bearing shaft 19 is guided in a passage opening of the guide plate 11.
  • Two needle bearings 24 are provided for mounting the counter holder 8.
  • a clamping device 27 which has a screw 25 and washer 28 which clamps the notching tool 5 on a holder 26.
  • the notching tool 5 is designed, for example, as a disk having cutting teeth on the circumference, which can be rotated in each case after a reduced cutting action, or as a similar cutting tool.
