Definitions

  • foil knives with fixed window position and foil knife with variable window position are used. Due to the foil knives protruding above the surface of a cylinder, depending on the format, e.g. of an envelope window in various positions cut out.
  • US Pat. No. 6,766,733 B1 is a replaceable foil knife known.
  • the foil knife disclosed therein is one with which a variable window position can be produced.
  • the variability of the arrangement of the window position relates only in the axial direction.
  • Known solution is a window cutout for cutting a window in a fabric, such as a sheet of paper, by means of Einitatistatten (pins) in the axial direction attached to different positions. This means that the window opening can be variably cut in the axial direction with respect to the envelope to be processed.
  • the rotatable knife roller comprises at least one rotatably mounted on a rotatable shaft roller body part, in the peripheral surface magnetic elements are arranged in rows, wherein at least one foil knife is provided which has a thin, flexible base plate made of a magnetically permeable material on the at least one integrally formed sharp cutting edge protrudes. This is formed into a predetermined cutting shape, wherein the base plate has a front and a rear edge and two opposite side edges and the foil knife is held flat by means of the magnetic elements on the peripheral surface.
  • the roll body part holding and positioning pins are arranged in series. These protrude at a height h radially out of the peripheral surface, which corresponds approximately to a thickness d 1 of the base plate, wherein in the base plate in a front edge adjoining the front region a number of cutting edge aligned slots are aligned, the Width b corresponds to a width b 1 of the holding and positioning pins. These protrude into the slots, so that the foil knife in the region of a slot length axially displaceable and implementable, seen in the circumferential direction of the second body part, however, is firmly and reproducibly positioned.
  • the present invention is based on the solutions of the prior art, the object of the flexibility to cut differently shaped envelopes - to give an example - to allow with foil knives on only one magnetic cylinder, in particular in the positioning of preciselyschchnenden window.
  • the window position in which an envelope window is to be cut out in a specific format within the format section is to be changed in the axial and radial (x, y) direction.
  • displaceable window foil knives are mounted, which is done by means of a Pinangn principle. This means that already existing and used window film knife with corresponding openings for the Einitatipins (see, eg DE 109 25 612 A1 ) can be used.
  • the pin bar of the magnet roller is used or pins are used on the format foil knife.
  • the placement of the window foil knife can be done within a recess of the format foil knife.
  • the recess is e.g. in the area of the format mirror in almost the entire cutting area, if the contour cutting edge can only be positioned on film knives designed as side strips.
  • the variability of axial window positions results from the consistent application of the Pinological principle.
  • the variability of the radial window position is achieved by means of prefabricated adapter plates.
  • the orientation of these adapter plates is carried out either by means of the above-mentioned Pinologicalntamas or by applying to a lower recess edge of the format film knife.
  • a grid can be covered at radial positions. Other radial positions can be achieved by shortening the adapter plates.
  • the cylinders on processing machines are designed as magnetic cylinders, ie have permanent magnetic properties.
  • These magnetic properties of the lateral surface of the cylinder allows the fixation of format foil knives and window foil knives supported by magnetic force.
  • these are usually subjected to negative pressure.
  • the entire lateral surface of a cylinder is crossed by a number of holes, of which, for example, in rows and segments extend a number of openings to the lateral surface of the cylinder.
  • the format foil knives or window foil knives are held in their predetermined position on the circumference of the cylinder so that centrifugal forces occurring at high rotational speeds can be absorbed, ie both the format foil knives and the window foil knives reliably on the circumference of the cylinder being held.
  • the format foil knives and the window foil knives are held on the circumference of the knife roll primarily due to the magnetic force; the negative pressure of the knife roller acts in relation to the fixation of the format film knife and the or used window foil knife rather supportive.
  • pressurizing the knife roller envelopes are kept during transport, for example, are held by pressurized with vacuum suction openings which are formed when cutting the envelopes Textilschnippel and fixed by the acted upon with negative pressure openings and later discharged from the transport path.
  • the window foil knives can be attached to already existing pin strips of the format foil knives used. It may be both an immediate hooking of a window foil knife to a corresponding pin bar, e.g. be performed on an inner edge of a format sheet knife;
  • the use of different width and circumferentially longer trained adapter or embossing plates is possible, so that within a cut-out area of a format foil knife, the window foil blade is fixed in any axial or circumferential direction.
  • the window foil can also be fixed by adapter strips on the circumference of the cylinder. The adapter strips can be attached both magnetically and under pressure on the lateral surface of the cylinder. The negative pressure is particularly recommended at higher rotational speeds, i. high production speeds due to the high centrifugal forces occurring during operation.
  • the adapter plates used can either also be aligned by means of Pinologicalnkars or fixed by applying it to one of the cut edges of the format film knife in position. Due to the different configuration of adapter plates, e.g. can be formed as cuboidal or strip-shaped embossing or adapter plates, all current window positions can be achieved on all popular formats of envelopes to be produced window positions within a recess of a format foil knife.
  • a set of adapter strips or adapter plates is used, so that the window foil blades can be easily and quickly converted to the new axial or radial position of the window position when converting a format to be processed.

  • Another, second window foil blade 78 is mounted with its slot-shaped openings on holding and positioning pins 66 at the trailing end of the adapter element 74. This in turn has at its leading end also in a row next to each other arranged slot-shaped openings 68 which are connected to in FIG. 11 not shown holding and positioning pins 66 are fixed. Also, this further window foil blade 78 is fixed by hanging in a formed on the lateral surface 22 of the knife roller 10 series of holding or positioning pin 66 by the action of the magnetic force of the magnetic elements 50 and by the action of the negative pressure.
  • Another third window foil blade 78 is in turn fixed by being hooked into the strip or row of holding and positioning pins 76 formed on the lateral surface 22 of the knife roller 10, by the action of the magnetic force and by the negative pressure of the lateral surface 22 of the knife roller 10.
  • the integrally formed format foil knife 54 can accommodate at least three identical window foil blade 78.
  • window foil blade 78 can be accommodated in the upper half of the bounded by the boundary 86 recess 84 in the upper half of the bounded by the boundary 86 recess 84 more window foil blade 78 can be accommodated.
