<p>A scrap shearing machine having a straight blade shearing machine (20), a wide, open type supply channel (30), a side hydraulic ram (63) for compressing, in the supply channel, metal scrap (35) from a side, and a feeder (40) for sending the compressed metal scrap to the shearing machine. In order to compress long and solid metal scrap by relatively small drive force, the side hydraulic ram (63) is adapted to laterally compress the metal scrap only at a certain limited longitudinal portion which is shorter than the overall length in the longitudinal direction of the supply channel (30). The side hydraulic ram (63) is associated with a downward hydraulic ram (53), and the downward hydraulic ram (53) is adapted to downwardly compress the metal scrap (35) only at the limited longitudinal portion prior to operation of the side hydraulic ram (63). Respective drive systems of the straight blade shearing machine (20), the feeder (40), the side hydraulic ram (63), and the downward hydraulic ram (53) are associated with a general control device (70) for operating and controlling them in a predetermined operation sequence.</p> |
