<p>A programmable conveying, cutting and sorting apparatus for concrete reinforcing steel bars (16). The bars are initially fed into the apparatus transversely, two at a time, by a reciprocating insertion device (17) whose movement automatically triggers the lowering of idler roller (30) against drive rollers (18). Cutting is initiated when the ends of the bars strike longitudinally adjustable stops (58) or end measuring devices (74) disposed-down the conveying path, with a vertically displaceable cutter (52) being forced down in shearing relation to a fixed cutter (50). Immediately after cutting the still-fed bars rotate cutter (52) about a pivot axis (56) to provide rapid, substantially continuous operation. Length sorting is implemented by a program controlled turnover grid (84).</p> |
