Abstract
Abstract The belt comprises at least one layer of strong material (e.g., canvas) stitched to at least one layer of absorbent material (e.g., terry cloth). The stitching is arranged in a herringbone pattern of inclined rows extending from apices along the centre line, and the edges are free of further stitching. This arrangement facilitates squeezing of absorbed liquid laterally out of the belt between squeeze rollers.
