Method for controlling feed pitch of metal strip in stamping press in stamping line, involves allowing finger to be movable between two positions, and releasing fingers in notch before new step of advancing strip

摘要

The method involves providing an indexing finger (8) located close to a longitudinal edge (2a) of a web (2). The finger is movable between two positions. Another finger (9) is allowed to be movable between a position in which the latter finger is free with respect to the longitudinal edge, and another position in which the latter finger is engaged in a notch (7) after each step of advancing the strip. The fingers in the notch are released before new step of advancing the strip.
