ABSTRACT:
A machine for stretching fabric over a panel frame has a surface for supporting the frame in a preferably horizontal position. The frame is usually rectangular, and sets of opposed jaws are arranged around the perimeter of the supported frame, with the jaws being interconnected by a pneumatic piston-cylinder actuator. One of the jaws is also connected to a second actuator, which induces downward movement of the jaws to stretch the grasped fabric over the panel frame. The latter actuators are energized by a common pressure source to equalize the tension on the opposite sides of the panel frame.
