ABSTRACT:
A clamping device for a screen member in vibratory screening apparatus comprises a frame member 1 on which is mounted an inflatable stocking 7. In use, the clamping device is inserted into the basket 21 of the screening apparatus so as to overlie the screen member, and the inflatable stocking 7 is expanded so as to press the screen member against a portion 17, 19, 31 of the basket 21 while the clamping device reacts against a further portion 17, 19, 33 of the basket 21. This pressure from the stocking 7 holds the screen member in place. Preferably the screen member has a screen 13 mounted in a frame 15 and the stocking 7 presses against this screen frame 15. The stocking 7 may press against the periphery of the screen member only or may press against other parts of the screen member as well.
