摘要 |
The invention concerns a multi-colored composite foil (14) of thermoplastic synthetic material and a method and a device for its manufacture. The device according to the invention comprises a first extruder device (20) with a first forming tool (22), whereby the extruder device produces a first plastified synthetic material melt and extrudes same by the first forming tool in order to manufacture a carrier foil or carrier layer (10) with a first color (28) and with a depression. The device can, furthermore, comprise at least one second extruder device (24) with a second forming tool, whereby the second extruder device produces a plastified synthetic material melt and extrudes same by means of the forming tool in order to produce a top foil or top layer (12), which has a second color and which fits, surface-flush, into the depression of the carrier layer or carrier foil. The device according to the invention has, in addition, a calender (32) which joins the carrier foil, surface-flush, with the top foil fitted into the depression of the carrier foil under the influence of pressure and heat and which flattens out the produced surface.
