Abstract
A method of yarn piecing by splicing in a fasciated yarn spinning unit is disclosed herein, according to which an end of a fleece to be lapped over a broken end of a yarn is formed by stopping a preselected pair of drafting rollers and, if any, its preceding pair or pairs of drafting rollers, in response to a yarn-break signal. After a fleece end is thus prepared, the front top drafting roller is lifted from its bottom counterpart, and a broken yarn end on the yarn package is brought reversely through the false-twisting nozzle and on through a gap formed between the separated top and bottom rollers of the front pair. In order to allow the yarn end to overlap with the fleece end over the desired length, the lifted front top roller is brought back into pressing engagement with its bottom roller in close relation to the time at which the nip of the front pair of drafting rollers is reached by the fleece end which is advanced by restarting the previously stopped drafting rollers. The overlap of the ends is then moved into the false-twisting nozzle wherein it is pieced up under the effect of rotary streams of air.
