Title:
THREAD RETAINING/DRAWING-OUT APPARATUS, AND THREAD WINDING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2012/120963
Kind Code:
A1
Abstract:
A thread end of thread retained on a thread retaining unit is reliably drawn out. When a thread (Y) supplied from a thread supply unit to a thread retainer (70) is separated from the thread (Y) retained by being wound on the thread retainer (70), a tubular winding arm (75) for winding the thread (Y) on the thread retainer (70) is caused to generate a flow of air toward the thread supply unit so that the thread end wound on the thread retainer (70) can be drawn out by suctioning, and then the thread end is connected with the thread end on the thread supply unit side. A tip portion of the winding arm (75) extends in a tangential direction of the thread retainer (70) in plan view. In the thread retainer (70), the thread (Y) is wound by the winding arm (75) across a lower end portion of six rollers (71) disposed along a virtual circumference (R) and a winding support surface (74a) of slope members (74) disposed between the rollers (71). An upper surface of the lower end portion of the rollers (71) and the winding support surface (74a) form a plane substantially continuously extending along the virtual circumference (R) such that the thread (Y) can be wound in a substantially circular shape in plan view.
