Bobbin thread times and methods bobbin thread winding device

摘要

PROBLEM TO BE SOLVED: To enable the reliable entanglement of thread to a bobbin, which is the initial process of thread winding, by treating thread with at least one property among properties of strong cores, easily slidable surfaces, rigid surfaces, and little twisting or no twisting into a loosened state such as a single- fiber state, a state close to a single fiber, or a fluffed state in a short single fiber, etc. ;SOLUTION: The bobbin thread winding device 30 provided with both a thread holding means 36 to hold bobbin thread L from a bobbin thread supply source and a thread winding means 20 to wind the bobbin thread L held by the bobbin thread holding means 36 on a bobbin shaft is provided with the thread loosening device 160 to loosen the tip part of the bobbin thread L. The thread loosening device 160 is a rotary-type thread loosening mechanism with a pair of thread loosening members 161 and 162 to sandwich the tip part of the bobbin thread L, to rub and loose the twisting of the tip part of the bobbin thread L by rotation.;COPYRIGHT: (C)2000,JPO
