摘要： A process for extruding a section or the like body from an ingot is such that an ingot is introduced into a bore of a container and, by means of an extrusion stem, is fed in the direction of extrusion into a shape-giving opening in a die. Before the ingot enters the die opening, it is pushed out of the container by an amount corresponding to the width (t) of a collar whereupon a disk-shaped slice is sheared off the free end of the ingot and removed. The free end of the ingot is then pushed onto the die opening. In order to carry out this process a shearing tool is provided after the end of the container facing the die and a moveable shearing blade positioned over that entrance to the container bore The disk-shaped slice should preferably be sheared away together with a residual butt of the previously extruded ingot which faces away from the die. To that end a shearing tool with two shearing blades is provided and can be moved radially with respect to the longitudinal axis (A) of the container bore.
