ABSTRACT:
A shearing apparatus of this invention provides a uniform thread shearing, and a high discharging capability for sheared threads. Even when a discharging power is raised by increasing a suction power of a suction box, a cloth having threads subjected to shearing and passing over a shearing table, will not float from the shearing table thereby providing uniform shearing and preventing damage to the cloth. An outer wall having a shutter forming a slit is hinged to the suction box such that it is pivotable with respect to the wall of the suction box so that an angle between the outer wall and the suction box can be adjusted. Inside the suction box, there is provided a rotating blade device comprising a cylinder with a plurality of radially disposed ditches on the surface of the cylinder and longitudinally extending blades fixed substantially equidistantly and parallel each other. A fixed blade is disposed adjacent to the rotating blade device, confronting the slit of the suction box and forming a part of the wall of the suction box. A hollow shearing table having many small apertures in its surface and connected to a suction device is disposed in front of the slit, outside the suction box and is movable with respect to the slit of the suction box. A permeable conveyer may be disposed on the shearing table or a rotatable roller having many apertures may be disposed at the top edge of the shearing table to confront the slit of the suction box.
