Definitions

  • the invention relates to a device for cutting flat Sheets or sheets of paper or plastic, consisting of from a first edition assigned to the clippings Knife part and one perpendicular to the support with the first knife part interacting second knife part, the opposite the first knife part a cutting edge designed with a suit having.
  • Cutting devices of this type are used in paper processing Industry and similar companies. You serve i.a. the cutting of stacked sheets of paper or foils to a certain format size or trimming stapled or bound magazines, book blocks, brochures, Catalogs etc.
  • the sheets stacked on top of each other on a horizontal base are subjected to a high cutting force on one side, which is exerted by the obliquely running cutting edge of the movable knife part or by the movable knife part engaging on one side edge of the sheet or product stack, and a force lifting the leaves to the side of the knife edge triggers a horizontal force component tending to the upper stack area for lateral displacement of the sheets.
  • this one-sided force action causes a correspondingly unfavorable load on the drive elements.
  • the object of the present invention is therefore a cutting device to create in the manner mentioned at the beginning with which largely eliminates the disadvantages listed or with which is high with a relatively high processing power Cutting quality can be achieved.
  • this object is achieved in that the cutting edge of the second knife part has two leg-like sections which, in the cutting position, form an obtuse angle distributed on the opposite cutting edge of the first knife part or on the material to be cut.
  • the driven knife parts are evenly applied and machined with largely regular cutting force. The displacements are prevented and the load can be evenly distributed over the knife parts and the stressed machine parts.
  • the cutting time and the stroke of the knife parts are shortened noticeably; The service life of the knife parts is increased and the cutting quality is improved compared to other cutting principles.
  • the obtuse angle ⁇ advantageously has an approximately perpendicular to Cutting edge of the first knife part running bisector on, so that an even distribution of the leg-like Sections of the cutting edge of the second knife part opposite the cutting edge of the first knife part. of the too cutting sheet or product stacks can arise which the cutting forces are appropriately distributed.
  • leg-like sections can be uneven on the opposite cutting edge of the first knife part be distributed so that they differ in the cutting position acute angle with the cutting edge of the first knife part form and accordingly also in the case of to be circumcised irregular cross-section of a printed product or stack can be optimally used, for example in headers and / or Foot trim.
  • the device according to the invention proves to be favorable for the Pruning single or stacked multi-leaf Printed products, such as magazines, brochures, book blocks, Books or stacks of loose sheets or sheets as well as stacked sheets Pathways in the paper processing industry.
  • 1 and 2 has a movable second knife part 3 fastened to an upper knife bar 2 and a first knife part 5 interacting with it, and fastened to a lower knife bar 4. Both knife parts 3, 5 are shown in a cutting position which immediately begins . Between the two knife parts 3, 5 there is a stapled or bound magazine 6 which is cut on the trailing open side. This magazine 6 can be trimmed both at a standstill and during transport with knife parts 3, 5 running in the same direction on the head and foot and on the open side. The direction of funding for the journals is specified by F.
  • a table 7 or the like, which precedes or follows the cutting plane, serves as support 7, which forms a coplanar plane with the cutting edge 8 of the first knife part 5.
  • the second knife part 3 has a cutting edge 9, which is formed from two sections 10, 11, which one on the opposite cutting edge 8, respectively. the material to be cut or the magazine 6 form an obtuse (open) angle ⁇ .
  • the second knife part 3 is arranged such that the bisector of ⁇ is approximately perpendicular to the support 7 or. to the cutting edge 8 of the first knife part 3 or parallel to the cutting movement of a knife part 3, 5.
  • the support 7 can also move with the clippings.
  • Fig. 1 further shows that the leg-like sections 10, 11 of the knife edge 9 are evenly distributed on the opposite cutting edge 8 and each form an acute cutting angle ⁇ , ⁇ - of about 1 to 5 ° - whereby the cutting force to two Sides distributed approximately evenly and a correspondingly balanced load will arise.
  • the acute cutting angle ⁇ , ⁇ can be chosen to be unequal in size, that is to say, for example, that the cutting angle on the side of the collar where there is an elevation is flatter than on the other side open side of the product to be cut.
  • the device 1 can be used for trimming individual or stacked multi-sheet printed products, such as magazines of all kinds, brochures, book blocks, books, catalogs or also loose sheets and webs, both at a standstill and in an uninterrupted run.
  • CH - 2489/94 is a facility disclosed for trimming flat printed products and be further developed by the subject here could.
  • the second knife part 3 - also for its fastening - slot-like through openings arranged next to one another 12 for fasteners such as screws in the Cutter bars 2 are anchored so that it is possible to second knife part 3 into a relative to the first knife part 5 to be inclined.
  • the first knife part could also be used 5 can be designed accordingly adjustable.
