Abstract
A method and apparatus is disclosed for restarting a yarn spinning apparatus, such as a wrap yarn spinning machine, and which involves the removal of an initial low quality interconnection in the form of a pieced-up segment, and its subsequent replacement with a high quality interconnection, without interrupting the yarn advance. For this purpose, the apparatus includes a first yarn accumulator for receiving the portion of the yarn which includes the pieced-up segment, and this portion is severed and removed. A second auxiliary yarn accumulator is also provided which is attached to a yarn splicing device, and which is operative to accumulate the advancing finished yarn during the brief time the splicing operation occurs. The brief accumulation time of the finished yarn in the auxiliary accumulator avoids the troublesome step of removing a large quantity of finished yarn from an accumulator.
