Abstract
A magnetic roll for use in roller pairs of a drafting system on a textile machine. Each magnetic roll includes a central pole member having a rare earth magnet positioned on either side thereof. An end pole member is provided adjacent each magnet, and a cot is provided next to each end pole member for gripping and propelling fibers between the roller pairs of the drafting system.
Claims30
A magnetic roll for use in conjunction with a driven roll of a drafting roller pair in a textile drafting system, comprising:
- at least one circumferentially extending rare earth magnet having a first end and a second end opposite said first end;
- at least one resilient member associated with said at least one rare earth magnet for engaging the driven roll of the textile drafting system;
- and
- support means associated with said at least one rare earth magnet and said at least one resilient member for substantially coaxially supporting said at least one magnet and said at least one resilient member together for rotation in the textile drafting system.
A magnetic roll for use in a textile drafting system, comprising:
- at least one pole member having a first side and a second side opposite said first side;
- first and second rare earth magnets;
- said first magnet being positioned adjacent said first side of said central pole member, and said second magnet being positioned adjacent said second side of said central pole member;
- a first end pole member positioned adjacent to said first rare earth magnet, opposite said first side of said central pole member, and a second end pole mender positioned adjacent to said second rare earth magnet, opposite said second side of said central pole member;
- at least one shaft member associated with said first and second end pole members for maintaining said central pole member, said first and second rare earth magnets, and said first and second end pole members in substantially coaxial alignment with respect to one another.
A magnetic roll for use in a textile drafting system, comprising:
- at least one central pole member having a first side and a second side opposite said first side;
- first and second rare earth magnets;
- said first rare earth magnet being positioned adjacent said first side of said central pole member, and said second rare earth magnet being positioned adjacent said second side of said central pole member;
- a first end pole member positioned adjacent to said first rare earth magnet, opposite said first side of said central pole member, and a second end pole member positioned adjacent to said second rare earth magnet, opposite said second side of said central pole member;
- and
- at least one shaft member associated with said central pole member aperture, said first and second magnets, and said first and second end pole members for maintaining said central pole member, said first and second magnets, and said first and second end pole members in substantially coaxial alignment with respect to one another.
A magnetic roll assembly for use in conjunction with a roll of a drafting roller pair in a textile drafting system, the magnetic roll assembly comprising:
- first and second rare earth magnets, each of said first and second rare earth magnets having an end;
- and
- at least one pole member positioned between the end of said first rare earth magnet and the end of said second rare earth magnet.
