Abstract: Strip material is stored in stock rolls on cassettes positioned in side by side relationship and moveable on a carriage between different roll storage positions and a splicing position. Each cassette has a guide member engageable with a guide member on a stationary support for splicing a leading edge of strip material from one roll to a trailing edge of strip material from another roll. A single actuating cylinder and shaft on the stationary support moves the guide members together providing splicing of strip material on all the rolls.

Abstract: Disclosed is a motor driven arm rehabilitation device which includes a rotatable forearm support structure capable of being rotated back and forth through a predetermined arc at a predetermined speed and with a predetermined force applied, and a fluid motor such as a rotary actuator for rotating this support structure. Rotation of the supporting structure causes alternate flexion and extension of the patient's arm. The arc of rotation, frequency of rotation and force applied can be varied in accordance with the patient's needs. Associated with the forearm supporting structure is a wrist stabilizer which causes alternate pronation and supination of the wrist as the forearm is alternately flexed and extended. The device also has an upper arm supporting structure.
