<p>For use in a textile folding and stretching operation, a clamping appliance has a first pivotable clamp arm mounted on a wall or the like by a bracket and a second pivotably mounted on the first. In order to actuate the pivotable clamp arms without a separate operating lever, a spring loaded over-centre toggle lever connects the second clamp arm and the bracket. The first clamp arm is mounted displaceably on the bracket. One arm of the toggle lever is connected to the bracket by securing means that can be released upon displacement of the first clamp arm relative to the bracket. This ensures against undesired opening of the clamp arms in use. Elements are provided for the adjustment of the toggle linkage to adjust the insertion opening betueen the two clamp arms.</p> |
