Abstract
Open-end spinning is accomplished by means of placing similar static electricity charges on an anode member and an inlet anode nose member mounted in a spinning chamber near a feed roller, and by placing a charge opposite said anode member on a cathode member mounted at a downstream portion of the apparatus; introducing an air stream through said inlet anode nose member into said spinning chamber and discharging it through an outlet opening; within said spinning chamber, separating a single fiber from the strand of sliver or roving delivered from feed rollers; charging said single fiber with the same charge of static electricity as the inlet anode nose member, and; hoisting said single fiber into a yarn extending upstream from a twister.
Claims10
A pneumatic and static electricity open-end spinning method, characterized in:
- charging an inlet anode nose member and an anode member arranged near said nose member and mounted on the wall of a spinning chamber near feed rollers, and oppositely charging a cathode member mounted at a downstream portion of said chamber;
- introducing an air stream from said inlet anode nose member into said spinning chamber and discharging it through an outlet opening;
- within said spinning chamber, charging a single fiber with the same charge as the anode nose member which fiber has been separated from a strand of sliver or roving being delivered from a feed roller;
- twisting said single fiber into a yarn projecting upwardly from a twister rotating continuously and arranged downstream of said spinning chamber.
An electrostatic and pneumatic open-end spinning apparatus, comprising:
- a feed roller;
- a stationary spinning chamber with a large cavity arranged downstream of said feed roller;
- an inlet anode nose member, charged with static electricity, mounted in said spinning chamber with a narrow clearance between itself and the feed roller;
- an anode member, charged with the same charge as said nose member, arranged near but spaced from the inlet anode nose member, and mounted in said spinning chamber;
- a rotating twister arranged at a downstream position;
- a cathode ring;
- charged oppositely from the anode member, arranged coaxially with said twister but not in contact with the twister;
- a suction source which draws air through the inlet anode nose member into the spinning chamber and then, out of the spinning chamber.
An electrostatic and pneumatic open-end spinning apparatus, comprising:
- a feed roller;
- a stationary spinning chamber with a large cavity arranged downstream of said feed roller;
- an inlet anode nose member, charged with static electricity, mounted in said spinning chamber and arranged close to the feed roller with narrow clearance;
- an anode member, charged similarly as said nose member, arranged near but spaced from the inlet anode nose member, and mounted in said spinning chamber;
- a rotating twister arranged at a downstream position, and charged opposite to the anode member;
- a suction source draws an air passing through the inlet anode nose member and drawn from the spinning chamber.
