FIELD: plastic working of metals. SUBSTANCE: apparatus has slab 1, die 2 formed as rocking prism with cutting edge, a set of adjustable stops 5, buffer member 6, guides 4 and punch 7 mounted in roller supports in slab 1. Punch 7 is made in the form of drive roller with projections staggered in its surface. The process of cutting-through-drawing by projections arranged in one row is initiated the moment similar process by projections of previous row is terminated. It allows discontinuities in material members defining cells adjacent to projection apex to be eliminated. EFFECT: increased quality of products by eliminating discontinuities in members, reduced labor consumption and simplified maintenance by efficient usage of design peculiarities of tool for supplying material to working station. 2 cl, 1 dwg
