Abstract
A pressing tool including means for cutting a blank from a strip fed longitudinally into the tool. The cutting means comprise a stationary lower punch carried by a press table and a vertically mobile upper die normally located above the punch and intended to be moved in the direction of this punch by the mobile press slide. Means are provided for cutting the end scrap from the strip, these means comprising shears having a stationary blade and a mobile blade, a device for transfer of a cut blank, prestamped blank, or stamped blank, from the station which the blank occupies to the following station, and means to lift each cut blank to the level of the transfer device. The stationary blade is carried by the support of the punch while the mobile blade is carried by the die.
