Friction false twister - has disc shroud to increase safety and reduce noise and simplify yarn laying

摘要

The yarn friction false twisting appts., using two discs where their edges lie over each other with a partial overlap, has a cladding around the circumference of each disc, coaxial to the disc mounting on the swing lever. The cladding has an edge which is flush with the edge surface of the disc. Pref. the shrouding can be moved between a working positon around the discs to a position where the disc edges are free. The cladding is a ring around the disc circumference, and a trapzoid shrouding. The frame is on a pivot mounting at the machine frame on an axis parallel to the disc axes. The friction false twisting assembly is mounted to a carrier beam parallel to the longitudinal machine axis, together with a number of other friction false twisting assemblies. The carrier beam swings on an axis parallel to the longitudinal axis of the machine, and can be secured in a selected swung position. Each disc is driven by a motor coaxial to the disc axis, at the free end of the swing lever, so that the positioning of the motor gives the placing of the disc. The swing lever is formed by a projecting flap from one side of the motor housing. ADVANTAGE - The insertion of the yarn into the assembly is easier, and the operator safety is increased together with less operating noise from the fast-rotating discs. The discs, which are sensitive to high temps., are also shrouded.
