<P>PROBLEM TO BE SOLVED: To provide a processing apparatus capable of enhancing the on-off operation precision of a shaking arm. <P>SOLUTION: The processing apparatus 20 is equipped with a rotary member 40 for holding a cylindrical part 50 to unidirectionally rotate around the center axis thereof, the shaking arms 63 supported on the rotary member in a freely shakable manner so as to be opened and closed with respect to the outer peripheral surface of the cylindrical part and a cam mechanism for converting the rotation of the rotary member to shaking to transmit the same to the shaking arms. During period when the continuous work 1a wound around the cylindrical part over a predetermined range in the rotary direction thereof is passed through the predetermined range by the rotation of the cylindrical part, the part of the work wound around the cylindrical part is held and released by the on-off operation of the shaking arms corresponding to the part of the wound work to form a part to be processed. The cam mechanism is equipped with a first cam 81 for magnifying the rotation over the predetermined angle of the rotary member to the rotation of a first cam follower node 84 corresponding to an angle larger than the predetermined angle and a second cam 75 for converting the magnified rotation of the first cam follower node to the shaking of a second cam follower node 76. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
