Abstract
Detachable screen cloths (14) are fixed on a screen cloth element (11) having a rigid support frame (12, 13) serving as a holder and intended to be fixed in the screen frame (10) of a screening machine. The detachable screen cloths (14) have a rigid screen cloth frame (30, 31) surrounded at least partially by elastomeric material. The rigid mounting frame (12, 13) of the screen cloth element has a guide device (32, 33) which is laterally open for receiving and holding the screen cloth (14). The screen cloth (14) is in sliding engagement with the guide device (32, 33) during the insertion thereof into the guide device. The screen cloth (14) and the guide device (32, 33) have inter engaging surfaces preventing, during the screening operation, relative movements between the screen cloth (14) and the rigid mounting frame (12, 13) of the screen cloth element in directions making an angle with the plane of the screen cloth.
