Closer comprises a cylindrical housing defined by a front end and a rear end, the housing being formed with an axial bore having an enlargement in the front end. An air-driven cylinder is fixedly mounted in the bore and has an axial drive shaft reciprocable therein extending toward the front end and terminating in an impact head normally in an inward position. Reciprocably disposed in the enlargement is an annular trigger loosely surrounding the impact head and normally in an outward position extending down beyond the front end of the housing and movable to an inward position when the housing is lightly depressed over the fastener. An actuator in the housing is moved by the trigger as it approaches its inward position to activate the cylinder and slam the impact head downward to close the fastener. In a modification the cylinder is replaced by a solenoid.

A snap button includes a female member and a male member engageable therewith. The female member comprises a hollow cylindrical body including a cylindrical hub and an annular flange extending radially outwardly from and integrally formed with the lower end of the cylindrical hub and terminating in a flat rim, the annular flange having an annular abutting portion formed between the lower end of the cylindrical hub and the flat rim, the flat rim and the annular abutting portion being spaced axially of the hollow cylindrical body; an annular cap having a through hole formed centrally therethrough to define an inner rim therearound and an outer folded brim formed around the outer edge, the folded outer brim coming into gripping engagement with the annular flange so that the annular cap is fastened to the hollow cylindrical body with an inner surface of the annular cap abutting on the abutting portion and with an annular space provided between the lower end of the cylindrical hub and the inner rim of the annular cap; and an annular spring disposed in the annular space.

Apparatus for making a molded plastic snap-fastener in-situ on a porous substrate, such as fabric. The apparatus includes dies defining a mold cavity therebetween and an ultrasonic head for melting and shaping plastic in the mold cavity. A hinged stripper surrounds a die and when actuated engages the fabric to remove the molded fastener from the die cavity.

A snap fastener attaching system employs a moveable carriage assembly which is controlled in linear motion by a belt system coupled to an actuator mechanism. The carriage assembly includes clamping means which are sequentially operated to clamp a garment on the assembly after emplacement by an operator. The depression of a start button enables the actuator to traverse a shaft. Associated with the actuator is a pivotable arm which is located in proximity to a selected shaft of a cam-containing turret assembly. As the actuator moves, the carriage moves proportionately due to the belt coupling system. Each time the actuator arm contacts a cam along the turret shaft, a fastener is emplaced on the garment by the snap fastener attaching machine associated with the carriage assembly. When the last fastener is emplaced, the apparatus is automatically returned to the starting position to enable accommodation of the next garment.The attaching system employs adjustable guide mechanisms and a turret can be selectively activated to enable the apparatus to accommodate different size garments; while further including a conveyor or garment handling assembly for automatically transporting the garment from one machine to another for attaching corresponding counterparts to the garment.
