Abstract

A machine, especially for hot forming of plastic foil, is provided with force elements 14, which in a predetermined work cycle bring a holding-down element 20 to press against the workpiece formed of the material web 38 in order to secure it during the forming. The force element brings the punch 17 and cushion 28 in contact with the material piece so as to shape it according to the contour of the cushion, preferably by means of an air pressure difference at the two sides of the material piece 38. A motion transmission arrangement 10 extends beyond the edges of the material piece 38 and has elements 11 for carrying the punch 17 and the holding-down element 20 on one side of the material piece. The motion transmission arrangement further extends beyond the material piece to the force element 14, which is located on the other side of the workpiece together with elements 24 for carrying the cushion 28. Its force element 22 can be arranged on the same side of the material piece as said support elements 24 and the aforesaid force element 14. The force elements 14, 22 are arranged underneath the material piece 38, whose primary plane is preferably situated in an essentially horizontal position. <IMAGE>
