ABSTRACT:
A stretcher frame comprises a plurality of frame parts which face one another at their corner surfaces. A rotary stretching element has portions thereof extending into both recesses of opposing corner surfaces to prevent relative movement between the parts in a direction parallel to an axis of rotation of the stretching element. The stretching element includes a first bearing surface bearing against a wall of one frame part, and a second bearing surface bearing against a wall of the other frame part. The second bearing surface is non-symmetrical relative to the axis of rotation whereby the frame parts are spread apart in response to rotation of the stretching element.
