Abstract
A service unit (16) for a cheese-producing textile machine (1), in particular an open-end spinning machine, has manipulation devices for repairing ordinary yarn breaks, an auxiliary yarn transport device (34) for piecing yarn following a cheese/empty tube exchange, and a control device (24) storing a first program with optimal operating parameters for piecing an ordinary yarn break and a second program setting differing operating parameters for producing a safety piecing following a cheese/empty tube exchange.
Claims4
A service unit for a cheese producing textile machine, comprising manipulation devices for repairing a yarn break, an auxiliary yarn feeding device for piecing a starting yarn end following an exchange of an empty winding tube for a completed cheese, and a control device storing a first program with operational parameters for controlling a yarn piecing operation producing a yarn piecing for repairing a yarn break with the dimensions of the yarn piecing having a profile essentially equivalent to the yarn being spun and a second program with operational parameters which differ from the parameters of the first program for controlling a yarn piecing operation to produce a safety yarn piecing for piecing a starting yarn end following an exchange of an empty winding tube for a completed cheese with the dimensions of the safety yarn piecing exceeding the cross section of the yarn being spun.
