Definitions

  • the present invention relates to a device for Satinizing a film according to the preamble of claim 1 and a method for operating the device according to the preamble of claim 10.
  • a device for Satinizing a film according to the preamble of claim 1 and a method for operating the device according to the preamble of claim 10.
  • Such a device is disclosed in US-A-5 598 774, the movable suspension being a the roller axes allow synchronization of both rollers.
  • the arrangement and design of the teeth is described in nothing is disclosed in this document.
  • a device for satinizing is known a film in which the pyramidal teeth have a square floor plan, with the sides aligned parallel or perpendicular to the roller axes are and in the circumferential direction the teeth of a roller by one half the tooth width compared to the teeth of the other roller are offset.
  • This known satinizing device was Underlying problem, despite the relatively fine Interlocking of the satin rollers both high quality Satination as well as mutual synchronization in particular of the satin rollers in the sense that only one of the rollers is driven and the other roller takes along. It had been shown that the required Conditions are not readily met if both Rollers were similarly provided with hardened teeth to achieve an attractive service life for the rollers.
  • the rollers were aligned that the circumferential rows of teeth of the both rollers are in the same plane, which means the teeth in the area of engagement of the rollers against each other, flank to flank lie, which is an inevitable take, so to speak the freely rotating roller by the driven roller is achieved.
  • Satinizing rollers have proven their worth as long as satin foils, especially packaging foils, consisted mainly of aluminum.
  • films in use or even prescribed which are mainly made of paper.
  • These slides are much stiffer than aluminum foils, and it has shown that the known satinizing rollers meet the requirements no longer suffice, because the higher proportion of paper leads to that the tendency of the film to settle after satinizing deform, e.g. to curl up, increases rapidly.
  • GB-A-2 311 949 discloses flexible packaging material to satinize, the rollers arranged in this way are that one tooth of a roller is between four teeth each the other waltz comes to rest, but with the teeth are arranged obliquely to the roller axis and thus by this Helical gear locking of the rollers is necessary.
  • a satinizing roller is known from US-A-5 036 758 known, on which the teeth flattened, their edges broken and arranged obliquely to the axis.
  • the invention also relates to a use of the inventive Apparatus according to claim 9 and a method for operating the device according to claim 10.
  • the solution according to claim 1 is a combination of partly known measures, which together form a very precise machining without significant deformation per se very problematic foils allowed and not just one stable mutual entrainment and synchronization of the Roll rotation, but also an optimal satin finish guaranteed regardless of the material to be satinized.
  • the basic structure of the satin finish is based on referred to above-mentioned U.S. Patent No. 5,007,271.
  • a foil tape is placed between two toothed satin rollers carried out, one of which is permanently stored and is driven while the other rotates freely on one Is mounted and by spring force, pneumatic or otherwise resilient with adjustable pressure against the driven roller can be pressed.
  • Both satin rollers have the same type Surface serration on, in Figure 1 in development is shown schematically. It is a matter of pyramid-shaped teeth in the circumferential direction or through the direction of rotation indicated in the arrow and in the axial direction are arranged at right angles to it in rows. As mentioned Figure 1 is a schematic representation, d. H. the pyramidal teeth are shown as if they were the precise geometric shape of a pyramid with a sharp tip would have. The teeth were the same with the known one Execution trained.
  • the tooth tips according to FIGS. 2 to 5 are flattened, d. H. the teeth are shortened by one Amount ⁇ A ( Figure 3), in practice this reduction at least 2%, preferably up to 25% of the theoretical geometric tooth height.
  • the edges the pyramid-shaped or truncated pyramid-shaped teeth broken which can happen, for example, that after machining the gearing post-processing through general material removal, for example by etching or galvanic removal, such there is an abrasion mainly on the tooth edges he follows.
  • Figures 7 and 3 schematically show a comparison of the Embossing process in the position according to the invention (FIG. 7) or conventional tooth position (Figure 8).
  • Figures 7 and 3 schematically show a comparison of the Embossing process in the position according to the invention (FIG. 7) or conventional tooth position ( Figure 8).
  • Figures 7 and 3 schematically show a comparison of the Embossing process in the position according to the invention (FIG. 7) or conventional tooth position ( Figure 8).
  • the dashed lines are the relevant refraction lines, and it turns out that the embossing length at tooth position according to the invention is substantially longer than with conventional tooth position, and the film nerves not only neutral, but also in broken symmetrical diagonal direction.
  • the preferred embodiment described above stands out through simplicity, operational safety, long service life the rollers, good satin finish regardless of the film material and simple operation.
  • the described tooth shape which the dynamic engagement of the Roll teeth in the stable, preferred mutual Tooth position is beneficial.
  • the rollers can be of different or the same height Teeth are formed, d. that is, the tooth pitch must naturally match within the limits given above, but the flattening can vary.
  • the non-driven, free-running roller with lower teeth it will worn out a little faster, but can be lighter be replaced as the driven roller.
  • the rollers can also be used with pre-or Rough orientation, z. B. with a Coarse toothing on the edge of the roller or on the side of the rollers when merging the rollers when starting up intermesh and roughly pre-orient the rollers and so that the correct interlocking and subsequent final transfer of the rollers to the stable position support.
  • the means of orientation must be sufficient Show the free mutual movement of the game Allow rolling to the stable position.
