Abstract

A yarn return unit for returning a yarn into a delivery unit of a textile machine during a piecing process includes a yarn-guiding section configured to guide and position the yarn with respect to the delivery unit. A blowing unit generates an air flow for returning the yarn from the yarn-guiding section into the delivery unit, the blowing unit defining a flow direction of the air flow. The yarn-guiding section includes an open contour that defines an insertion area through which the yarn is inserted into the yarn-guiding section transversely to the flow direction of the air flow.
