Definitions

  • the invention relates to a laminating device with, in particular, a table top for guiding laminate to a separating knife.
  • a relatively thin and "endless" film of a plastic material is fed with a sheet to a laminating unit comprising a film roll and a sheet roll, and lamination occurs in the nip.
  • the adhesion between sheet and film can be achieved by various process variants (eg water -, Thermo or SF-laminating.) Frequently, the individual, successive sheets underlaid supplied to the rollers to prevent the adhesion of the film on the platen roller.
  • the laminate Before further processing in a downstream process, the laminate must again be singulated into individual sheets, since the sheets are connected to one another by the film.
  • EP-B-706863 describes a device for separating laminate with a, at the speed of the laminate with mitbewegbaren cutting knife, which is designed as a thermal cutting knife whose rotational speed is computer controlled.
  • DE-A-10028070 discloses a flat table top containing recesses for optical sensors. A format-controlled check of the sheet leading edge is to be made possible.
  • a feed table according to DE-A-10355459 is intended to allow safe guidance of sheets from the feed table to a transfer cylinder, which is why a table top is guided concentrically around a frame point of a rotating pregripper and slightly below a circle of the gripper charge strips.
  • flat and folding tabletops are still known.
  • Also known is an embodiment in which the sheet web is clamped before and after the cutting knife by means of rollers on transport rollers. The tabletop between the rollers is below the arcuate path, so that the stretched arcuate path during the separation process practically does not come into contact with the table. Both embodiments have the disadvantage that they are not suitable for high separation performance and separation accuracies.
  • the invention has for its object to avoid the disadvantages of the prior art and to provide a laminator with a table top, which allows a highly accurate and parallel conditioning of the sheets on the cutting blade.
  • the object is solved with the features of claim 1.
  • the table top is a flat sheet that is pre-stressed.
  • the preload allows height adjustment, good contact in the separation area and high dynamics (high machine performance).
  • the tabletop is electrically insulated and heat resistant at least in the separation area.
  • the maximum occurring temperatures of the cutting blade are up to 550 0 C.
  • the tabletop forms a circular segment-shaped profile. The remote from the cutter side of the table top is loosely clamped.
  • Fig. 1 a cutting device with rotating hot knife
  • Fig. 2 a tabletop assembly
  • FIG. 3 shows another embodiment of a table top arrangement.
  • a laminate 3 consisting of a plastic film 1 and a sheet 2 is fed in a known manner by a laminating unit 4 continuously to a cutting device 5 with a hot knife 6.
  • the isolated sheets arrive at a transport table 7.
  • a biased (spring-loaded) two-piece table top 8 which is anchored on the, the cutting blade 6 facing side in a fixed clamping.
  • the fixed clamping is assigned a height adjustment 9.
  • the side facing away from the cutting blade 6 of the table plate 8 is slidably clamped loose in a sheet guide 12.
  • the two parts of the table plate 8 are firmly connected by means of an intermediate Teflon bar 11.
  • the Teflon bar 11 is supported by an Al support profile 13 and grants the flatness in the contact area to the cutting blade 6.
  • the inlet side of the Teflon bar 11 is chamfered to ensure a gentle "emergence" of the rotating cutting blade 6.
  • the transport table 7 has a belt carpet and a tear roller 10, which is also adjustable in parallel for sheet separation.
