ABSTRACT:
There is disclosed a positive extraction mechanism for use in a textile molding apparatus preferably of the type having a female mold member and a male mold member. The mold members move into molding relationship with a fabric therebetween to form a cup-like article which is retained by one of the members. The positive extraction mechanism moves into intimate contact with the retaining mold member after the other mold member has been retracted. The extraction mechanism includes a plurality of pins which may be actuated by power means into engagement with the molded cup-like article. Each pin is spring biased away from the molded article so that the spring will retract its associated pin within the extraction mechanism upon removal of the power means. Upon retraction the molded article will leave the positive extraction mechanism. This occurs after the molded article has been carried away from the mold member.
