Abstract
A clip applying machine for tubular casings which comprises opposing clip jaw members that pivot toward each other to gather the casing and position a die member on one side of the casing. A punch member is advanced from the other side of the casing to feed a clip around the casing and against the die member. The jaw members are pivoted by a first piston/cylinder mechanism which is pivotally connected to the jaw members and the punch is advanced by a second piston positioned within the first piston. In this manner the punch and the second piston are driven in two stages, i.e. first by and with the first piston and then by air pressure that directly and further advances the second piston.
