Abstract (en)
Yarn winding apparatus to produce a package with a conical end is known in which a friction roller (15) drives a rotatable package (11), the yarn Y being supplied over a disc (17) eccentrically mounted to rotate on an L-shaped lever (18) pivoted by a pin (19) to a vertically reciprocating layrail (20), the other end of the lever (18) having a slide block (22) running in a guide (23) which rotates round a pivot (24) as the package (11) increases in diameter. When used with substantially non-extensible yarn, the speed of rotation of the disc (17) is liable to vary considerably, causing unacceptable yarn package characteristics. The invention overcomes this problem by passing the yarn over a dancer roll (29) on its way to the disc (17). The dancer roll is mounted on a spring balancing means (31) which allows it to move towards and away from the disc.
