APPARATUS FOR TREADS TEXTURING Russian patent published in 1996 - IPC

FIELD: textile equipment. SUBSTANCE: twisting spindle has ferromagnetic steel cylindrical tube with three cylindrical outer chords made of magnets with radial magnetization. Middle chord is spaced by two thirds of cylindrical tube length from its lower end. Two other chords are located in symmetry to middle one on both sides of it. Nonmagnetic steel head made in the form of cylindrical tube is fixed to upper outer part of the tube forming undetachable coupling with it. Perpendicular to axis of cylindrical tube stone twisting pin is inserted in the head. Two grooves, that provide thread servicing, are made on plane, that is perpendicular to axis of bush and on which cylindrical tube axis is located. EFFECT: improved quality of thread texturing. 2 dwg
