Abstract

At one end of the base are prestraighteining rollers mounted in a frame and having adjustable loading. The bottom roller drives a reinforcing bar into a cage rotating about its axis and driven by a motor. Adjustable rollers complete the straightening operation. The bar passes between another pair of rollers, adjustable for pressure and driven by a motor, which also drives the prestraightening rollers and an eccentric arm. The bar reaches a stop at the end of the machine, operating cut off shears previously set to size. The eccentric arm then operates knock off arms to eject the length.
