Abstract: A method and apparatus for feeding to a fixed-axis punch, successive sections of a strip of flexible material for the purpose of punching out from the strip plates of a predetermined size and shape, said strip being punched out in a staggered pattern along three rows of axes which are parallel to the median longitudinal axis of the strip. The invention is applicable, in particular, to the stamping out of circular plates of identical diameter from a thin metal strip, which plates are to be shaped in their final form by successive stampings performed by a series of inter-related punches located in a transfer machine.
