ABSTRACT:
A hide stretching apparatus, in particular one for the tentering of hides for drying. The apparatus comprises a stretching frame with a number of mutually spaced radial sliding guides. The stretching clamps gripping the edges of the hide have been arranged to be reciprocatingly movable along the sliding guides. The stretching frame is placed upon a special hide changing table carrying under each sliding guide a clamp displacement member. The clamps carry jaws which attach to the edge of the hide to be stretched. The jaws are opened and closed by means of a lever turnably carried on the clamp. The clamp displacement member has two gripping members, which can be made to engage the clamp on both sides according to commands given, for the displacing of the clamps reciprocatingly along the sliding guides. The clamp comprises a brake engaging with the sliding guide and which with the jaws in closed position prevents the displacement of the clamp towards the center of the stretching frame. The lever turning the jaws into their opened and closed position pushes, when the jaws are opened, the brake against the force of a spring into a position such that the clamp is free to move in either direction, whereby the clamps can be moved into clamping position and into detachment position.
