<p>A process and apparatus for treating a hide (10) with a fluid. The hide (10) is stretched longitudinally and/or laterally. In one embodiment the hide (10) passes from upstream rollers (14) to downstream rollers (15) rotating at a higher speed to stretch the hide (10) longitudinally. Left hand rollers (16, 17) and right hand rollers (18, 19) can be angled to the line of travel (20) so that the hide is stretched laterally. In a second embodiment the hide (10) is clamped between upper and lower edges (45u, 45l and 46u, 46l) and the lines of clamping are moved apart, longitudinally by separating sets (40, 41) of clamping means and/or laterally by arranging the lines of clamping at an acute angle α to the centre line (20) and increasing that angle towards 90°. Liquid is sprayed onto the underside of the hide (10) while stretched through manifold (31) having nozzles (32).</p> |
