A variable rake shear comprises a housing (8), a first blade (1) mounted in a first blade mounting (4), a second blade (2) mounted in a second blade mounting (3); and control means (5) to control movement of one of the first and second blade mountings to shear the material. Each blade mounting is movable in at least one dimension relative to the housing. One of the first and second blades is an active blade (1) and the other of the first and second blades is a passive blade (2). The shear further comprises a rake adjustment mechanism (6a, 6b) for at least one of the first and second blade mountings (3, 4) and the mounting (4) for the active blade (1) further comprises a torque tube linkage mechanism (10, 11, 12). |
