DRAWING MACHINE FOR RODS AND TUBING

摘要

An arrangement by which elongated articles are drawn through a carriage rolling on guide tracks extending along the drawing path. Rollers mounted on the carriage are pressed against the guide tracks through hydraulic cylinders to develop the friction required to move the carriage along the guide tracks. Hydraulic motors on the carriage are mechanically linked to the rollers for the purpose of supplying the necessary driving power of the carriage. The traction or driving force required to move the carriage for the drawing operation is developed entirely through friction between the rollers and the guide tracks.
