Abstract: A scraping bar is disposed between the positions corresponding to endless chains of a thin sheet material transferring member. A nipping mechanism is disposed behind the scraping bar in its travelling direction. A thin sheet material having been subjected to the punching step, which is nipped by the nipping mechanism, is pulled together with the scraping bar to carry out a transfer step. Disused portions of the thin sheet material remaining on a lower surface plate is pushed out by means of the other scraping bar subsequently passing between the upper and lower surface plates. It is possible to transfer the thin sheet material in a stable manner by the scraping bar, thus permitting to carry out a high-speed transfer step. There is no need for formation of uncut portions between portions to be punched into a prescribed shape and the remaining disused portions and the punched products after the separation of the disused portions has an excellent finishing condition.
