ABSTRACT:
A plastic molded snap fastener including a stud head having solid thin annular base flange and a top, the top and the flange being held in spaced relation by radial ribs preferably in the form of a cross piece, the top being annular but "flattened" on the outer perimeter in the area of the ends of the cross piece. Where the plastic is compatible with the plastic of the fabric, the fastener parts may be molded directly on the fabric. In a modification the base flange is split by a plane perpendicular to the axis of the fastener part. The base fabric is sandwiched between the parts of the flange. This modification is useful where the plastic of the fastener is not compatible with the plastic of the fabric. The invention also includes a mold apparatus for forming the fastener on a stip of fabric wherein core pins on one side of the mold cooperate with spring-pressed ejection pins on the other side and with cavities in the mold retainer plates to shape the parts. The preferred mold apparatus also includes punches for perforating the fabric preparatory to the molding operation.
