Abstract:
A method of producing a fastener product having a strip-form base and a multiplicity of fastening elements extending from a side of the strip-form base, the method comprising the steps of:applying resin to a rotating mold roll, the mold roll having an outer surface for forming one side of the base and defining a multiplicity of cavities extending inward from the outer surface, under conditions which cause the resin to fill the cavities and form said side of the strip form base on the outer surface of the mold roll;stripping from the mold roll a preform product having said strip-form base and a multiplicity of upstanding, preform stems formed in the cavities of the mold roll and extending from said side of the base; andregistering a longitudinal position of the preform stems with a rotational position of a heading roll while passing the preform product against the heading roll to form, from resin of the stems, a head on each of the preform stems, to form said fastener elements, the heading roll defining a multiplicity of cavities about its periphery which receive the preform stems and form the heads to overhang sides of their stems in multiple directions to form mushroom fastener elements.
