<p>1485111 Shearing SOC DE CONSTRUCTIONS MECANIQUES DE CREIL 5 April 1976 [7 April 1975] 13704/76 Heading B3W The cutting edges 1, 2 of a pair of blades of a rotary shear are rectilinear, located in a plane 3, 4 passing through the respective axis of rotation x-x, y-y of the blade, inclined to that axis at the same angle A and so disposed that at all times they are symmetrical relative to the plane 5 which is normal to a plane defined by the axes x-x, y-y and passes through a straight line 6 equidistant between them. The plane 5 coincides with the plane of travel of strip to be sheared and the cutting point travels along the blades. The drums 7, 8 may carry more than one pair of such blades.</p> |
