Winder with automatic bobbin change includes shaped guide lever for transfer tail winding to hold yarn away from traverse guide and gradually release it

摘要

A continuous yarn winder is equipped for automatic bobbin change and places a transfer tail on the tube (9) at the start of each package. An arm moves along a rail (38) and causes a slide lever (31) to tilt so that a guide lever (43) places the yarn in an entrainment groove in the tube (9). The guide lever (43) has a shaped yarn guide (52) that holds the yarn away from the traverse guide (3) and gradually releases it with the help of a stationary guide (56) into the traverse region. The guide (52) is made of wire or sheet metal and is shaped to have an initial guiding surface perpendicular to the hinge axis of the guide lever (43) and a second region towards the middle of the travel of the traverse guide (3).
