Abstract

In a method for winding yarn on a yarn winding region of a bobbin in a textile machine having a yarn supply device delivering yarn to the bobbin, which method includes after severing of the yarn between a full bobbin and the yarn supply device, drawing off by means of a suction device, the yarn which continues to be delivered by the yarn supply device, and, at the commencement of winding a bobbin, the yarn coming from the yarn supply device is engaged by a hook-shaped catch element which rotates with the bobbin, a tie on reserve winding is formed from the yarn downstream of the catch element by positioning the suction device so as to bring the yarn leaving the yarn supply device to a position where it intersects the plane of rotation of the catch element at the diameter at which the catch element is located and, immediately after the yarn is caught by the catch element, bringing the yarn subsequently coming from the yarn supply device into the winding region and simultaneously extracting the yarn downstream of the catch element from the suction device and winding it on the bobbin adjacent the winding region to form a reserve winding.
