Abstract
In the production of shaped plastic elements using deep-drawable thermoplastic film, a tension frame is required to clamp the film. The tension frame is formed by lengthwise and transverse frame parts, on the outside edges of which is located one angle clamp on each. The angle clamps can be actuated by means of closure levers into a releasable clamping position, in which the clamp arms of the angle clamp press with force against bottom fixing members of the frame parts.
