ABSTRACT:
A carriage drawing machine for uniformly drawing and cutting-to-length drawn elongated material and having a main drive shaft with means for driving a drawing machine carriage so as to advance the elongated material, a severing device and means for coupling the severing device to the main shaft each time the elongated material is to be severed, the severing device including two cutters disposed in a common plane and eccentrically coupled to the main drive shaft, the cutters being rotatable in opposite directions and in synchronism with the advance of the elongated material during the severing operation, means defining between the two cutters a travel path for the elongated material being advanced, each of the cutters including a ring, a knife extending radially outwardly from each ring toward the travel path between the cutters, and means cooperating with the cutters for adjustably controlling the knives to follow the drawn material and to orient the knives perpendicularly to the direction in which the material has been drawn, the control means being linked to each ring at a substantially diametrically opposite point thereof from the knives.
