<p>Continuously rotating shears (10) to shear to size metallic strip fed continuously at up to around 20 meters per second and having a thickness of from 0.5 mm to 5 mm and a width of from 500 mm up to at least 1500 mm, comprising two blade-bearing drums (11, 111), the drums (11, 111) being supported at the ends by rotary cams (13, 113) governed by shearing command means (15, 16), the drums (11, 111) being positioned between the sides (18) of the frame (17) and being made to rotate by an external source of motion, each drum (11, 111) including an external gear (20, 120) cooperating with an inner toothing (26, 126) of a rotary tube (21, 121) which has an outer toothed wheel (25, 125), the two rotary tubes (21) being connected by the respective outer toothed wheels (25, 125) engaging together. <IMAGE></p> |
