Abstract
Textile yarn is fed beneath a permanent magnetic ring (A) to a driven bobbin, wherein a fixed ring (B) carried on a ring rail and having an extension (C) projecting inwardly beneath the permanent magnetic ring provides a physical enclosure about the permanent magnetic ring, which has a complementary peripheral surface. The fixed ring supplies a repulsive magnetic force causing the permanent magnetic ring to float in a maintained centered relation therein. The fixed ring may be comprised of either permanent magnets held in stacked relation by removable clips or electromagnets connected by a hinge.
Claims14
A textile yarn spinning apparatus having a driven bobbin and a traversing ring rail for distributing yarn thereon comprising:
- a floating permanent magnetic ring centrally positioned about said bobbin beneath which yarn is fed to said bobbin;
- a fixed ring on said ring rail carrying said floating ring centrally therein;
- said fixed ring encompassing said floating ring, having a portion extending above and below said floating ring;
- said fixed ring having a lower extension projecting inwardly beneath a surface of said floating ring;
- and
- means on said fixed ring supplying a repulsive magnetic force with respect to said floating ring, maintaining said floating ring centrally above said lower extension;
- whereby twist is supplied to the yarn passing between said floating ring and said fixed ring and then beneath a bottom surface of said floating ring for distribution upon said bobbin.
A method of assembling a magnetic ring used in the spinning of a textile yarn in an apparatus having a driven bobbin and a traversing ring rail for distributing yarn thereon comprising the steps of:
- positioning a floating permanent magnetic ring centrally about said bobbin beneath which yarn is fed to said bobbin;
- carrying said floating ring centrally in a fixed ring on said ring rail;
- encompassing said floating ring by providing said fixed ring with a portion extending above and below said floating ring and with a lower extension projecting inwardly beneath a surface of said floating ring;
- and
- supplying a repulsive magnetic force with respect to said floating ring, maintaining said floating ring centrally above said lower extension;
- whereby twist is supplied to the yarn passing between said floating ring and said fixed ring and then beneath a bottom surface of said floating ring for distribution upon said bobbin.
