Abstract: Dual vacuum cleaing heads are provided above the sheet of warp yarns at opposite ends of a slasher intake portion where the multiple section beams are mounted on a creel ahead of the sizing bath. The two suction heads thoroughly remove debris from the sheet of warps at two locations before the sheet enters the sizing bath. The suction heads are suspended by transparent vacuum hoses from overhead serially connected vacuum manifolds. One manifold is connected with a centrifugal fan which evacuates both manifolds and delivers debris to a collection tank immediately ahead of the fan and having a filter. Viewing windows and clean-out ports are provided in the system.
