<p>A shearing apparatus of this invention provides an uniform thread shearing, and a high discharging capability of sheared threads. Even when a discharging power is raised by increasing a suction power of a suction box 1, a cloth having threads subjected to shearing passing on a shearing table 8, will not float from the shearing table 8 thereby providing a uniform shearing and preventing from giving damages to the cloth. An outer wall having a shutter forming a slit 2 is hinged to the suction box 1, being rotatable with respect to the wall of the suction box 1 thereby adjusting an angle of said outer wall with respect to the suction box. Inside the suction box 1, there is provided a rotating blade 3 comprising a cylinder 4 having plurality of radially disposed ditch 5 on the surface of the cylinder where blades 6 extending lengthwise are fixed parallel each other. A fixed blade 7 is disposed close to the rotating blade 3, confronting the slit 2 of the suction box 1 and forming a part of the wall of the suction box 1. A hollow shearing table 8 having many small apertures on its surface connected to a suction means is disposed in front of the slit 2, outside the suction box and movable with respect to the slit 2 of the suction box 1. A permeable conveyer may be disposed on the hollow shearing table 8 or a rolling roller 11 having many apertures may be disposed at the top edge of the hollow shearing table 8 and confronting the slit 2 of the suction box 1. <IMAGE></p> |
