Abstract

Appts. for punching a series of large holes in extruded plastic film comprises a system of guide rollers and clamps for briefly halting successive panels of a continuous film opposite transverse bars which carry a series of tubular cutters and which reciprocate in response to toggle levers actuated by a bar linked with the film transport mechanism. Used esp. for mfr. of agricultural films for moulding, involving small holes for ventilation and larger holes for plant stems etc. The size and pattern of the holes is reproducible and adjustable (using inter-changeable cutter heads).
