ABSTRACT:
An apparatus by which artist's canvas can be uniformly stretched on a frame. A first edge flap of the canvas is stapled to an edge of the frame at enough locations to withstand a predetermined tension without tearing. Thereafter, the frame is stood vertically on its opposite edge with a second flap of canvas extending beyond the edge of the frame into engagement with a plurality of pins of a predetermined diameter, which pass therethrough at predetermined intervals. The pins are located at an edge of a flat, horizontal surface of the apparatus but at a predetermined distance below the surface. The frame thereafter is rotated 90.degree. downwardly tearing the canvas about the pins so that a predetermined tension in the canvas is established which depends upon the gauge of the canvas, the diameter of the pins and the distance between pin centers. The second edge is then stapled at enough points to prevent further tearing. Thereafter, an adjacent third edge of the canvas is stretched like the second but starting with the frame at about 45.degree. to the surface and is stapled to the frame. The fourth canvas edge is engaged with the pins with the frame in a vertical position, and the frame is rotated 90.degree. downwardly to a horizontal position tearing the canvas and establishing the predetermined stress in the other direction. The fourth edge is stapled to complete the operation.
