Eccentric cutters for longitudinally severing elongated material to be drawn

Eccentric cutters for severing continuously traveling elongated material comprising two eccentrics disposed in a common plane and eccentrically mounted in stationary bearing means, the eccentrics being rotatable in opposite directions and in synchronism with the travel of the elongated material during the severing operation, means defining between said two eccentrics, a travel path for the traveling elongated material, each of said eccentrics comprising a ring, a knife extending radially outwardly from each ring toward the other ring and toward said travel path between said eccentrics, respective means cooperating with each of said rings for controlling orientation of said knives with respect to the elongated material for severing the elongated material, said control means being linked to each ring at a substantially diametrically opposite point thereof from said knives, said control means comprising a rod, said ring being pivotably connected to one end of said rod at a location of said ring at which said control means are linked to the respective ring and extending from said pivot location thereof substantially parallel to said travel path, said rod being pivotable at the other end thereof at a fixed point, said stationary bearing means comprise rotary shafts carrying said eccentrics, and means coupled to another shaft for rotating said eccentrics in opposite rotary directions at the same speed of rotation, an interposed transmission disposed on said other shaft for adjusting the speed of rotation of the eccentric-carrying rotary shafts, and means for adjusting at least one of the angle of rotating means and the eccentric mounting of the eccentrics, and continuously variable intermediate transmission means for slightly varying the rotary speed of the eccentric-carrying rotary shafts so as to have an effect upon the length tolerances of the severed lengths of the material.
