Title:
FRICTIONAL OPEN END SPINNING METHOD AND DEVICE
Document Type and Number:
Japanese Patent JPS53134937
Kind Code:
A
Abstract:
There is disclosed a method of and an apparatus for frictional spinning yarn on the open-end principle. Continuously supplied separated fibers are deposited onto a first, perforated frictional surface provided on a rotary carrier for conveying the fibers to the mouth of a wedge-like gap defined by said frictional surface and another, second, frictional surface provided on another rotary carrier. The second frictional surface moves relative to the first-named carrier, in the opposite direction, and with the first frictional surface twists the fibers in the mouth of said wedge-like gap to yarn, due to a contact with the two frictional surfaces. The yarn is withdrawn sidewards relative to the direction of movement of the frictional surfaces while preventing the twist propagation. In accordance with the invention one frictional surface is concave and the other is convex. This results in a number of advantages, including the elimination of undesirable slippage of the yarn in the yarn building region.
