ABSTRACT:
Static tow inverting apparatus for inverting the overlap of overlapping layers of a continuous length filamentary tow band of textile material deposited onto the surface of a moving conveyor in relaxed condition for treatment, such as in the thermal heat setting treatment of a band of tow which has been subjected to a mechanical crimping operation. The tow inverter comprises a pair of stationary plates which are disposed above the surface of a moving conveyor to receive a continuous length of tow in a plurality of overlapping layers thereon. The opposed surfaces of the spaced plates define a downwardly curving passageway for gravitational conveyance of the overlapping layers of tow through a reversing direction of movement to deposit the same on the surface of the moving conveyor with preceding layers of tow overlying succeeding layers of tow in the direction of movement on the conveyor. The tow is thereafter longitudinally withdrawn from the conveyor surface with minimum disruption of the layers and individual filaments therein. The two plates are respectively manually horizontally and vertically positionable to accommodate tow bands of varying size, width and dimensional configuration, and one of the plates is supported for pivotal movement about a horizontal axis in response to a predetermined pressure exerted thereon to prevent possible blockage of the inverter by tow in the inverter passageway. Means are provided for adjusting the downward slope of a surface of one of the plates, if desired, to facilitate gravitational movement of the overlapping layers of tow through the tow inverter.
