Abstract
A method for winding up a yarn reserve on a winding tube for a bobbin. The method comprises the steps of: continuously sucking the spun yarn, causing it to move through a circular yarn guide-positioning element, removably arranged coaxially with a yarn suction orifice; removing yarn positioning element from the suction orifice while the yarn being supplied and continuously passing therethrough; positioning said element above a yarn adherence zone of tube; breaking the yarn passing through the positioning element allowing the supplied yarn end to fall down on the tube adherence zone and into guide device, with yarn end facing externally of the tube end, and forming yarn reserve turns before winding the yarn bobbin.
