Method and apparatus for producing yarn from fibrous tufts

摘要

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.
