摘要

A former or easy folding or carton cutouts comprises a forming bar and grooved plate. A longitudinal flexible plastics grooves strip with the groove lengthways works with a folding bar and a flexible longitudinal positioner strip which is slotted lengthways to accept the folding strip. The grooved bar and positioner strip connect releasably to one another when groove and slot lie parallel. The base of the grooved strip is coated in glue to stick the former to the cutter plate. The rigid plastics grooved strip can be connected by heating to the positioner and released from this. The slot in the positioner can taper inwards from the opening, finally expanding into an oval.
