ABSTRACT:
By combination and interaction of mechanical and aerodynamic forces, textile fibers in the form of tufts are processed continuously by deposition into a hopper, subjected to an initial tuft-opening and cleaning apparatus, discharged as smaller tufts into another hopper wherein a constant level is maintained. The smaller tufts are then continuously formed into a lap and fed to a secondary opening and cleaning apparatus. Fibrous stock is pneumatically doffed and conveyed from this single source through a blending, subdividing and distributing means, in equal amounts through conduits to multiple remote locations for continuous assemblage into identical fibrous ribbons, fed to fiber individualizing means and subsequently to open-end spinning units for further processing into yarn.
