ABSTRACT:
An indexing device for successively positioning a tool element relative to an apparatus adapted to perform a series of operational tasks on said tool element comprises a base, a reciprocally movable support mounted on the base, a fixing member adjustably mounted on the support for fixing the tool element thereto, a pivotable arm mounted to the base and extending between the support and the apparatus, an indexing abutment mounted on the arm and positioned thereon to contact a part of the tool element. The support is moved in a first direction to bring the tool element in a task performing position with the apparatus. The movable support has a pusher to contact the arm and to cause pivotal movement of the arm when the support is moved in this first direction whereby the arm and the abutment are moved away from the task performing position. Thereafter, the arm is returned to a subsequent task performing position when the support is moved in a second direction opposite the first direction.
