Definitions

  • the invention relates to a method for forming a female mold in an embossing device for paper processing machines the preamble of claim 1.
  • envelopes, paper napkins, paper tissues etc. are provided with embossments if necessary, e.g. with the imprint a company logo. These impressions are made during the Manufacturing process within a paper processing machine executed. Almost finished envelopes, blank envelopes, Paper napkins, paper tissues, etc. between two cooperating embossing tools, male and female, with one impression Mistake.
  • the raised embossing tool is made of hardened To manufacture steel and as a counter tool a softened Insert copper plate.
  • the raised embossing tool, the patrix into the Copper plate pressed in and there a negative image of the patrix, a die cavity shape.
  • the advantage here is that within the male and the female produced in a production machine stand in a precisely aligned position to each other and their fit to each other.
  • the duration of the break-in period is disadvantageous in the production of the die cavity shape and the resulting one Load on the roller bearings.
  • Embossing tools have been known recently, in which one Male made of hardened steel against a female made of a tough elastic Material, e.g. Plastic, what works at not too thick paper thickness leads to excellent embossing results. Also
  • This combination of materials is used during a running-in phase by means of the hard patrix in a plate made of tough elastic Material molded the hollow form of the die. This process is very time consuming and takes an average of 4 - 5 Hours. Therefore it goes without saying that the running-in process not made in a production machine itself becomes.
  • the object of the invention is a method to develop, using embossing tools directly in a paper processing machine can run in and the time to Creation of a female mold using a hard stamp, a patrix, is drastically reduced.
  • the advantage achieved with the invention consists in particular in that the running-in process of the embossing device to produce a Die mold directly in a paper processing machine and the duration of the running-in period from 4 to 5 Hours is reduced to 1 to 2 minutes. Besides, will with the use of a tough elastic thermoplastic Plastic for the counter tool an inexpensive and low-wear Solution provided that is also small Setting errors between the stamp and the counter tool are forgiven.
  • the invention is based on an exemplary embodiment, that is shown in the drawing.
  • Figures 1 and 2 is a simply constructed embossing device 1 shown on a conveyor belt 2 for envelopes is arranged. It includes machine frames 3 and 4, an upper one and a lower embossing roller 5,6 as well as a drive train of several Drive wheels 7,8,9 by means of the feed and discharge rollers 10,11,12,13 and the lower embossing roller 6 are driven.
  • the transport path 2 tangent from below are between the Rollers 10,6,11,12 guide plates 14,15,16,17 arranged the are attached to trusses 19.
  • the lower embossing roller 6 is by means of a drive shaft 18 rotatably mounted in the machine frames 3,4. she receives their rotary drive via the drive wheel 8 assigned to them outside the machine frame 4 rotatably on the drive shaft 18 is stored.
  • the upper embossing roller 5 can be positioned fix relative to the lower embossing roller 6. That's what she is for ends, rotatably in pivot bearings 20,21, added.
  • the Swivel bearing 20, 21 in turn is at one end by means of a Bolt 22 pivotally mounted on the machine frame 3.4 and is at its other end by means of a screw bolt 23, which engages in a fixed support pin 24, supported.
  • the upper embossing roller 5 has a shaft 27 on which a Stamp carrier 28 is clamped displaceably and rotatably.
  • the stamp carrier 28 consists of a support and a Clamping part 29, 30, which by means of screws 31 on the shaft 27 are clamped.
  • a wing 32 is milled on the support part 29, on the one a male part 33 with a raised embossing motif 39 is fixed by screws 34 aligned.
  • the pivot bearing 21 is a double gear 35 on the shaft 27 fixed mounted, which engages in a drive gear 36 that on the drive shaft 18 of the lower embossing roller 6 and is attached.
  • the double gear 35 consists of a the shaft 27 clamped gear 37 and a coaxial thereto, Adjacent 38 arranged to reduce the backlash towards the gear wheel 36 Direction of rotation relative to the gear 37 by means not shown Spring elements clamped. This technique is general is known and is not shown and described here.
  • the lower embossing roller 6 comprises the drive shaft 18, on the one Slid on the roller body 40 and there rotatably with the help of a Clamping device 41 is locked. Between roller body 40 and the gear 36, spacer rings 42, 43 are arranged, the outer diameter are adapted to the roller body 40.
  • the roller body 40 is axially parallel over the entire length from the outside Groove 44 milled.
  • a plate-like counter tool 45 made of a tough elastic Material, preferably made of a thermoplastic material, aligned aligned. Left and right of the counter tool 45 the groove 40 is filled with filler pieces 46 which have an outer diameter bridge the groove 40.
  • counter tools 45 it is thus possible for counter tools 45 to be worn out by abrasion by heating the counter tool 45 again and intensifying it Embossing the stamp during the rotation of the embossing rollers 5 and 6 fully regenerate.
