<p>A vacuum or gas pressure clamp prevents movement of an elongate filter cloth used in a horizontal vacuum filter. The clamp includes a support frame and a planar supporting device having a perforated support surface for supporting the filter cloth. The vacuum clamp is mounted on the frame and is adapted for connection to a vacuum source so that vacuum can be applied to numerous holes in the support surface. An imperforate sealing sheet with a number of weights thereon extends over the support surface and in close proximity thereto. The filter cloth can be drawn between the supporting device and the sealing sheet. A vacuum can be applied to the filter cloth in order to prevent its movement in the longitudinal direction. In the gas pressure clamp, an enclosure extends around the supporting device and the sealing sheet and a positive air pressure can be provided in this enclosure.</p> |
