Abstract
Narrow strips of trim waste from high speed paper web converting and winding operations are drawn into a vacuum disposal system by a receiver which draws the trim strip over a flat surface aligned substantially parallel-planar with the strip off-running course. Such flat surface is flushed with an attached boundary layer of high velocity air which follows a smooth curve of the flat surface into the duct wall enclosure.
