Abstract: A printing device 300 for printing elements in the form of sheets 10, includes a platen press 310 which hot stamps to affix to each sheet 10 with a colored or metallized film from at least one stamping strip 320. A transport device 340 introduces each sheet 10 one after the other into the platen press 310 by pulling the sheet 10 by its front edge. The printing device 300 further includes a device 360 able to partially restrain each sheet 10 by its rear portion during the phase of introducing the sheet 10 into the platen press 310.

Abstract: A frame is designed for temporarily supporting a horizontal plate-like workpiece until it undergoes a vertical translation between guiding and squaring stops, which frame is located in a machine. The frame comprises lateral retractable supporting surfaces which are either edges of a horizontal flat bar or sides of a horizontal flat bar. When the supporting surfaces are the edges of the horizontal flat bar, the bar is mounted so that it can be moved from a straight line position retracted from the supporting of the sheet to a curved position for supporting the edge of the sheet. The bars can also be positioned utilizing the side and are moved either by pivoting or by a four-bar linking arrangement between the retracted and engaged positions. Finally, the bars can be mounted for rotation along one edge between the engaging and retracted positions.
