ABSTRACT:
A device for stretching a screen on a roller frame includes at least three torsion stations and a support structure. Each torsion station includes a torsion tool, for example, a wrench head, which can be attached to one end of one of the sides of the frame and torqued for the purpose of stretching the screen. Each torsion tool is attached to a shaft structure at a first pivot point. Each shaft structure is attached to the support structure at a second pivot point. Each shaft structure has a pneumatic or hydraulic cylinder positioned intermediately along its length for altering the length of the shaft structure between its first and second pivot points, thereby causing the wrench head to torque and rotate one of the rollers of the frame. A control panel allows the operator to activate all of the pneumatic cylinders simultaneously and with substantially equal forces, thereby resulting in a more rapidly and evenly stretched screen.
