Abstract
The starting or re-piecing of a yarn in an open end spinning machine is accomplished during full speed rotation of the spinning unit. A travelling piecer provides a fixed length of yarn to be back-fed into the spinning unit. A control which is responsive to the speed of rotation of the spinning unit causes the nip rolls to close together in order to deliver the new yarn from the spinning unit at the operating speed of the spinning unit.
