Abstract

Appts. for stamping fold lines into flexible plastic film includes a system for transferring a succession of pre-cut sheets singly to a pair of sets of chain driven clamps to locate the sheets precisely in the daylight of a stamping tool, and a conveyor for removing impressed sheets to a stacker. A support platen can drop and rise, on cam lifts, to allow the chain clamps to pass as appropriate. The upper platen carries a floating plate lined with a conductive metal (Cu) sheet carrying HF blades located by a suitable template. Spring-loaded caster blocks carry the floating plate for ease of movement, but allow the platen to depress the plate to make impressions. Spacers limit the depth of impression to e.g. half the thickness of the flexible sheet being treated. Used for accurate reproduction of the positions of fold axes in a series of pre-cut sheets, of PVC, cardboard, etc. prods. from a printing machine, opt. incl. large sizes, e.g. 80 x 120 cm. Design facilitates use of interchangeable, pre-assembled stamping tools by rapid exchange in a common press tool.
