Abstract:
A method for starting up a spinning process or piecing up after an interruption of a spinning process in a spinning position of a spinning machine, the spinning process including refining a longitudinal fiber array using a refining system having a predetermined degree of draft and imparting twist to the refined fiber array to form a yarn, the yarn being taken off from a twist imparting zone, said method comprising:severing the longitudinal fiber array between a refinement intake zone and a refinement delivery zone with respect to the refining system; generating a tapering yarn end zone at a free end of a yarn; positioning the free yarn end upstream from the twist imparting zone; generating a fiber array front end zone on the refined fiber array, the fiber array front end zone having an increasing mass as a function of the tapering of the yarn end zone by reducing the degree of draft of the longitudinal fiber array; and supplying the fiber array front end zone and the yarn end zone in an overlapping manner to twist imparting zone.
