Abstract

A yarn winding apparatus and a method for winding a continuously advancing yarn on a driven tube. A bobbin tube is clamped between two clamping plates that are rotatably supported on a package holder, and one of the clamping plates includes in its front edge facing the tube a catching slot with a catching nose that is directed in the direction of rotation, and a clamping slot for clamping the yarn. For purposes of threadup, the yarn is guided by a yarn guide and a suction device to the front edge of the clamping plate in such a manner that the yarn and the clamping plate move essentially in the same direction. To guide the yarn after having dropped into the catching slot, reliably to a lead-in plane of the clamping slot, the clamping plate has in its front edge a recess which undercuts the catching nose and the catching slot and forms a guiding edge on the edge of the clamping plate.
