Abstract

See full text

A fastening component of a separable fastener is molded out of two separate flows of resin joined under pressure in a nip as the fastening elements are molded in cavities of a cavity roller. The joined flows of resin travel about the cavity roller while being cooled, and are then passed about a stripping roller to pull the formed fastener strip from the cavity roller.
