ABSTRACT:
A continuous, moving length of substantially rigid thermoplastic synthetic resin material is marked with a hot die at spaced intervals along its length. The hot die is mounted for movement parallel to the direction of movement of the sheet from the sheet forming apparatus, and is actuated in coordination with a sheet cutter which cuts the continuous length into individual sheets so that a die mark is provided at the desired position on each sheet cut from the continuous length.
