Stretcher frame intended for the mounting of cloth for embroidering or canvas for oil painting including horizontal and vertical parts (1) and (2). In the joint between the vertical and horizontal parts en excentric stretcher element in the shape of a disk (4) is arranged. The disk has an excentrically placed hub (5) journaled in the first frame part (2) and by the turning of the excentric disk the frame parts are pressed apart. In this way it is possible to stretch the canvas or cloth fastened to the frame. Since the frame parts can be moved relative each other in the direction of the joint automatically the same tension force is achieved vertical as well as horizontal in the cloth or canvas. |
