ABSTRACT:
A filter is provided for removing particles entrained in a liquid, this filter comprising an endless fine mesh filter belt which is relatively short and which moves slowly over a supporting plurality of generally cylindrical rolls. This belt is a single layer of generally delicate woven metallic mesh and is provided with special means for moving and tracking the belt. This moving and tracking structure includes a link belt endless chain outside of each longitudinal side edge of the belt, these chains being rigidly attached over the adjacent edge of the belt. The belt can be held to its desired path around all of the supporting rolls and, preferably, over a suction box and past a cleaning point and returning to a starting point with no sensing devices, no special tracking rolls or tenter rolls, without powered devices, and with a minimum of close tolerance machining.
