<p>In scrap shears with a shear stand (1) on which a blade slide (11) is vertically displaceable in guides (8, 9, 34) arranged on the shear stand (1), a first blade (10) carried by the blade slide (11) and a second blade (12) interacting with the first blade (10) and arranged in a fixed position on the shear stand (1), it is to be ensured that scrap drawn into the shearing gap does not lead to deformations on the shears and thus to reduced operability of the same and that the scrap can be removed from the shearing gap with further reduced effort. To this end, the blade slide (11) is arranged according to the invention in such a way as to be movable against the action of elastic elements (22, 37) essentially perpendicularly to the shearing plane while a wider shearing gap is formed. In the event of scrap jamming in the shearing gap, the blade slide (11) can be pulled back despite the action of clamping force, and the scrap can be released solely by this sequence of movement. Preferred embodiments of these shears are provided with preloaded, elastic elements, for example annular-spring elements (22). <IMAGE></p> |
