Abstract
Abstract At least one wall portion is movable with respect to a fill box for precompression of scrap supplied thereto adjoining a cutter. Vertical pivot means journal the wall portions at a location transverse to direction of scrap supply. Fluid actuator means move at least one wall portion to swing about the axis of the pivot means. Fluid actuator means are also provided at each of opposite ends of at least one wall portion movable with respect to an opposite wall portion. Only a partial cover transverse to the wall portions is provided for facilitating supply of scrap between the wall portions of the fill box.
