Patent ID: 11247864

Abstract:
An improved fabric tension control apparatus and method consisting of a fabric handler with a feed roller, an idler roller and a take up roller and where fabric on the feed roller is transferred from the feed roller past the idler roller to the take up roller. A feed roller motor is connected with the feed roller and a take up roller motor is connected with the take up roller. A motion sensor tracks speed of rotation of the idler roller. A feed roller driver is connected with the feed roller motor and a take up roller driver is connected with the take up roller motor. A controller is connected with the feed roller driver, the take up roller driver and the motion sensor where the controller receives the speed of rotation of the idler roller from the motion sensor and where the controller sends speed adjustment instructions to the take up roller driver and the feed roller driver and where the speed adjustment instructions are sent to the feed roller motor and the take up roller motor such that the speed of the take up roller and the feed roller are adjusted such that the speed of the idler roller is constant so as to maintain a desired tension on the fabric as it is transferred.
