Abstract

High frequency heating and moulding tool head with an integral boundary cutter where the cutter is held clear of the material and the opposing platen during the dynamic phase of the cycle and is actuated by an increase in ram press. on the tool when the cut is required. PRef. for a circular section tool a channel in the annular cutter is engaged by balls extended radially by a spring set into the dynamic head. The cutter body is spring loaded so that it rises to engage the balls unless the cutting press. is applied. Avoids damage and energy dissipation due to arcing from the blade tip.
