Definitions

  • the invention relates to a three-knife trimmer according to the preamble of claim 1.
  • a triple cutter is one used in the bookbinding industry Cutting device with a cutting cell, which a Cutting plate with cutting strips or lower knives, one Press stamp with a format plate, a front knife and includes two side knives.
  • a triple cutter Books fed through a feed station that are already on the back are bound.
  • the task of the three-cutter is there in it, the books on the sides and on the front edge in one Work to the final desired format to cut.
  • a three-knife trimmer is known from EP 0 485 542 B2 to set up the side knives via motorized actuators changed at a mutual distance and so on the Book height can be adjusted.
  • the format plate and the Insert can be replaced manually.
  • the invention has for its object a three-knife of the type mentioned at the outset to improve that with a wide range of formats to be cut the setting of the cutting parameters faster and more precisely can be made and manual settings are omitted.
  • the side Cutting strips or lower knives no longer have one unit the insert.
  • the cutting strips or bottom knives can be actuated adjust over the entire book height. By the Cutting strips or lower knives are moved so that they with the cutting edge or cutting line of the side knives in line, takes place at every adjustable book height a precise cut.
  • press stamp during the Cutting process from both the front knife and the Side knives engage with the material to be cut stands.
  • Constant fixation of the material to be cut during the pre-cut and the side cuts enable exact adherence the dimensions of the format. This could also be the case by setting up the feed station, this would then have to be constantly engaged during the cutting process be with the material to be cut. Through permanent fixation by means of the press ram, the feed station can be set up be released again and during the Cutting process already capture another stack of material to be cut.
  • a positioning device that can be moved in and out possible, by means of which the material to be sliced can be gripped and can be fixed during the cutting process.
  • the press ram or the positioning device Preferably by the press ram or the positioning device only one for fixing the material to be cut the necessary force is applied during the cuts, while the actual Press alternately before the cuts through the Press bars can be applied.
  • the cutting line of the front knife facing edge of the pressure bars and the side knives in the upper rest position at a distance from the cutting line of the front knife be positioned and in the working position until at least Can be positioned on the cutting line of the front knife his.
  • the pressure strips preferably have at least one recess that can be positioned in the area of the back of the material to be cut is.
  • the length of the pressure bars can there are several recesses. This eliminates the need each adapted to the width of the book and possibly very extreme longitudinal displacement of the pressure bars.
  • the transitions between the recesses and the press surfaces rounded or flattened and / or with a flexible pad.
  • These support strips are used to sag the lower Blade positions of the material to be cut when the material is far apart Avoid cutting bars or lower knives.
  • Support areas in a space between the side Cutting bars or lower knives variable in width Support areas must be arranged, always the remaining Bridge the gap.
  • the support areas each designed as a flexible band or link band be guided on pulleys on both sides is or one side firmly clamped and on the other side is guided over pulleys.
  • FIG. 1 is a three-knife with Cutting cell 10 shown in cross section.
  • This includes a pressing surface 14 on which a stack of material to be cut 12 lies.
  • the pressing surface 14 has a width that is the smallest adjustable book height is measured.
  • the material to be cut 12 should however cropped to a much larger format become.
  • the separate cutting strips 18 have moved apart. The notches that appear when cutting the cutting strips are in alignment with the Cutting edge of side knives 20.
  • the material to be cut 12 is supported here by support strips 24, from below to the level of the cutting bars 18 and the pressing surface 14 are raised. Presses from above the material to be cut 12 is a stamp 16, which is also on the smallest adjustable book height is dimensioned. To fix the to be cut edges press strips 22, which on the Cuttings 12 can be lowered and the outer edges of the border by the side knife 20 predetermined cutting line.
  • Fig. 2 In an alternative embodiment according to Fig. 2 are in the Wide variable support areas 36 arranged that always bridge the remaining space. These support areas 36 are each designed as a flexible band, each firmly clamped on one side and on the other side is guided over pulleys 38.
  • FIG. 3 shows a top view of the illustration according to FIG. 1, in which also a front knife 26 and a Press bar 28 are shown for the front section. This are stationary here.
  • Fig. 4 shows a representation in which the lateral Cutting strips 18 and the front cutting strip 30 can be seen are.
  • the adjustable side cutting strips 18 limit directly to the front cutting bar 30.
  • Fig. 5 shows a side view of the three-cutter, in which the arrangement of the front knife 26 and the front pressure bar 28 are recognizable. There is also a side knife 20 shown. This is designed in the direction of the front knife so that it is in an upper rest position behind the Front knife 26 to lie with the front pressure bar 28 comes and in a working position the front knife 26 and engages under the front pressure bar 28. This ensures that side cuts to the front cut line or beyond.
  • Fig. 6 shows a detailed representation of the side pressure bars 22. These have recesses 34 which are parallel to one Back edge 32 of the material to be cut can be brought. This will achieved that when applying pressure before the cutting process only the unconnected sheet layers of the material to be cut be squeezed while leaving the thicker back out becomes. This prevents damage to the back.
  • the multiple arrangement of the recesses 34 ensures that that there is a simple adjustment to different Book widths, i.e. a different distance between the leading edge and the spine of the book, without substantial travel of the lateral pressure bars in the longitudinal direction.
