ABSTRACT:
In a garment-fastener-assembling apparatus, a drive mechanism for moving an upper or punch unit toward and away from a lower or die unit includes an air cylinder having a piston rod, and a toggle joint for transferring reciprocating motion from the piston rod to a punch of the upper unit as the toggle joint is contracted and extended. A contact member is mounted on the toggle joint so as to actuate a limit switch when the toggle joint is fully extended to a predetermined extent. The limit switch, upon actuation, produces an electrical signal for de-energizing the air cylinder to terminate the extension of the piston rod.
