<p>A hide stretching apparatus, in particular one for the tentering of hides for drying. The apparatus comprises a stretching frame (1) with a number of mutually spaced radial sliding guides (2). The stretching clamps (4) gripping the edges of the hide have been arranged to be reciprocatingly movable along the sliding guides (2). The stretching frame (1) is placed upon a special hide changing table (10) carrying under each sliding guide a clamp displacement member (12). The clamps (4) carry jaws (5 and 6) which attach to the edge of the hide (11) to be stretched. The jaws are opened and closed by means of a lever (9) turnably carried on the clamp. The clamp displacement member (12) has two gripping members (15, 18a) which can be made to engage the clamp (4) on both sides according to commands given, for the displacing of the clamps (4) reciprocatingly along the sliding guides (2). The clamp displacement member (12) also has a lever (9) driven by a cylinder (16), the lever (9) having a cam (19a) which can be brought into and out of engagement with a recess (9a) of the lever (9) on the clamp (4). The hide changing table (10) is fitted with radial support strips (24) to be placed adjacent to the sliding guides (2). A vertically movable pressmeans (28) is provided with radial press members (33) which can be pressed upon the support strips (24) in order to keep the hide (11) in position between the support strips and press members while securing the stretching clamps (4) to the margin of the hide (11).</p> |
