<p>An improved clip attachment apparatus includes a main drive cylinder operative to drive a punch against a clip. A mechanical linkage also connects the drive cylinder with a gate. Operation of the main drive cylinder simultaneously closes the gate to form the punch channel an drives the punch. The mechanical linkage includes a lost motion feature to insure that the gate will be closed prior to attachment of the clip around material gathered at the lower end of the punch channel. An improved knife for cutting the clipped material and an improved pneumatic circuit for sequentially controlling the drive cylinder and the knife cylinder are disclosed. Finally, an adjustable trigger mechanism for initiating operation of the clipper is disclosed.</p> |
