ABSTRACT:
Apparatus for shearing blanks from elongated workpieces and for pressing such blanks into screw blanks, bolts or the like in a continuous operation comprises a plurality of preferably cylindrical rotary elements, rotatable about parallel axes in such a manner that cooperating pairs of rotatable elements are rotated in opposite direction and so that blank receiving members on the rotary elements of each cooperating pair becomes successively aligned with each other. The plurality of rotary elements includes a central rotary element receiving sheared-off blanks and retaining the same during the pressing thereof until the final discharge, and a plurality of additional rotary elements arranged about the circumference of the central rotary element. One of the additional rotary elements serves to shear off blanks from the elongated workpieces and to transfer such blanks to the central rotary element and at least two further rotary elements cooperate with the central rotary element for forming the blanks through pressing.
