Abstract
Two pairs of opposed feed rolls are rotatably mounted on the upstream and downstream sides, respectively, of a bar cutting mechanism with respect to the predetermined traveling direction of the bar. Each feed roll pair comprises a fixed feed roll on one side of the bar and a movable feed roll on the other side, with the movable feed roll being movable toward and away from the fixed feed roll. A drive mechanism constantly rotates each pair of opposed feed rolls, so that the bar is fed only when being pressed against the fixed feed roll by the movable feed roll. The feed roll pair on the downstream side of the cutting mechanism is further jointly movable laterally of the path of the bar against the force of a spring for lessening the load exerted thereon, and for preventing the bending of the bar, when the bar is being cut by the cutting mechanism. Each feed roll may be provided with a multiplicity of teeth arranged circumferentially thereon and resiliently biased radially outwardly for positive engagement with a regular pattern of ribs on the bar.
