ABSTRACT:
A method and apparatus for yarn piecing on an open-end spinning machine is provided which includes a plurality of predetermined working programs for carrying out the piecing steps. To accommodate automated provision of quality pieced places in the yarn being spun, a yarn monitoring device is provided for detecting the quality of the piece place in the yarn, which device generates a signal controlling the selecting of one of the predetermined working programs for the next piecing operation at the spinning assembly. In particularly preferred embodiments, a storage device is provided for storing information as to the particular working program utilized during the last successful piecing operation at the respective spinning assemblies, with retrievability of this stored data to select the same successful piecing program for the subsequent piecing operation at such spinning assembly.
