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.

Abstract: An applicator assembly used in a processor for processing a photosensitive material with a developer liquid, in which an oscillating applicator supports and contacts an open-celled scrubber pad. The developing fluid is pumped through an adapter onto the applicator, which has a plurality of perforations at its front surface contacting the scrubber pad. The developer fluid is distributed through the scrubber pad which serves as a manifold to the surface to be developed and cleans from it unhardened emulsion of the photosensitive material, which passes the scrubber pad, inserted between it and a transport belt.There are provided means to prevent any shift between the applicator and the scrubber pad which might appear due to the oscillating movement of the applicator assembly transverse to the guide motion of the transport belt, which advances the photosensitive material.
