Abstract

A thermoplastic sheet is supported by a frame at the periphery thereof and a heating device (I) is arranged under the sheet. (I) comprises a horizontal frame with two side frames arranged at both sides of the frame, heating means e.g. electric heaters being secured to the frames. Both side frames are connected to the horizontal frame by two hinges so that when the softened thermoplastic sheet hangs, the horizontal frame is lowered by a screw being turned by a motor through two rotatable rods, while the side frames are inclined because the two upper ends are supported on two verticle rods.
