Abstract

Disc segments having a series of open-ended and open-sided cavities along their periphery are mounted alternately with plane faced spacer elements which can retract independently to allow ejection. A series of mated segments about a rotary mandrel form a peripheral surface against which a plastics material may be extruded to fill the mould cavities and cover them with an integral base allowing the moulding to be stripped from the machine as continuous sheet. Esp. for making self-fixing tapes (e.g. 'Velcro' (RTM)) from 'Nylon' (RTM) or 'Zytel' (RTM) (polyamides), with pref. 3-sided hook shaped pile about 1.6 mm deep, moulded in a more flexible grade than the material forming the support sheet.
