Abstract
An apparatus for take-up of textile fabric from a fabric producing machine is equipped with a fabric take-up frame, a fabric take-up roll supported on the frame for fabric winding thereabout, and a variable speed drive motor arrangement for rotating the take-up roll. A transducer roll or other suitable arrangement monitors tension in the fabric between the fabric producing machine and the take-up frame and is associated with a microprocessor or other controller to adjust the drive motor speed as necessary to maintain fabric tension in accordance with a predetermined tension program as the fabric is wound on the take-up roll, either for purposes of maintaining constant fabric tension or programmed tension variation over the winding operation. The take-up frame is separable from and movable independently of the fabric producing machine for transporting a fabric after a take-up operation to a subsequent processing station without rewinding of the fabric. In other embodiments, the fabric producing machine may be disposed at an elevation directly above the take-up apparatus or vice versa.
