ABSTRACT:
The improvement in a tow delivery apparatus downstream of a horizontally oriented stuffing box crimper of an unenclosed smoothly contoured curved perforated surface tangent to and sloping gradually downward away from the outlet end of the crimper to a moving conveyor belt. A vacuum is applied to the perforations in the curved surface at such a level so that the crimped tow is pushed down the curved surface by the tow exiting the crimper.
