Abstract
Apparatus for the extrusion of metal in the form of billets (4) cut to order from bars (44, 45) previously heated in a furnace (31), comprising an extrusion press (1) associated with a member for transferring each billet (4) to be extruded, parallel to itself, from a stand-by position (A), after cutting, to a loading position (C) in the axis of the press (1). For transfer of the billets the apparatus has a single member (2) moveable transversely to the extrusion axis and equipped with a gripper (5) of variable width, comprising at least two telescopic jaws associated with a device (6) for adjusting the extended lengths of the telescopic parts, such that each jaw covers a width substantially equal to the length of the billet.
