ABSTRACT:
A garment-fastener assembling apparatus includes a combined supporting and connecting mechanism composed of a pivot lever rotatably mounted on a frame and pivotably connected at its one end with the cylinder tube of a punch-driving cylinder and at the other end with a first pusher mechanism having a first pusher, and a spring-biased slide rod slidably mounted on the frame and having one end pivoted to the pivot lever adjacent to the cylinder tube. The slide rod is normally urged such that during a portion of the movement of the piston rod from the cylinder tube adjacent to the fully retracted position of the piston rod, the pivot lever operates the first pusher mechanism to retract and advance the first pusher. With the combined mechanism thus constructed, a punch and the first pusher can be driven in an accurate timed relation to one another. The first pusher mechanism includes a cushioning arrangement for preventing advancing movement of the first pusher if an element-feed passage is jammed by foreign matter. The stroke of a second pusher can be adjusted independently from the stroke of a die by a cam block connected to the piston rod of a die-driving cylinder.
