Abstract

A device is provided acting upon a multifilament continuous filament tow band to improve the levelness of the tow band prior to further processing by intermittently transversely displacing some, but not all of the filaments of said tow at different locations across the tow band and allowing a sufficient tow path line of travel to allow the filaments to achieve new equilibrium locations with respect to each other.
