Claims (1)

[Scope of claims for utility model registration] (1) Bobbin 2 with flange fixed to spindle 1
It is a mechanism for rotating and driving the thread together with the spindle 1 to twist the thread while feeding it upward, and is detachably attached to the collar 2a on the upper end side of the bobbin 2, and is centered around the rotation axis of the spindle 1. a base material 3 that rotates substantially integrally with the bobbin 2; and a base material 3 provided intermittently radially on the base material 3, the tip of which is disposed outward from the periphery of the collar 2a on the upper end side of the bobbin 2 during twisting. A plurality of protruding members 4 protruding into the
and a ballooning regulating ring 5 disposed above the collar 2a on the upper end side of the bobbin 2 and coaxially with the central axis of the bobbin, so that the yarn sent out from the bobbin 2 during twisting While in contact with the tip of the protruding member 4,
A twisting mechanism capable of tension control, characterized in that the ballooning is wound up while being in contact with the inner peripheral surface of the ballooning regulating ring 5 to regulate the size of the ballooning. (2) Collared bobbin 2 fixed to spindle 1
It is a mechanism for rotating and driving the thread together with the spindle 1 to twist the thread while feeding it upward, and the bobbin is arranged such that the tip part protrudes outward from the outer peripheral edge of the collar 2a on the upper end side of the bobbin 2. a plurality of protruding members 4 provided on the collar 2a of the bobbin 2, and a ballooning regulating ring 5 disposed above the collar 2a on the upper end side of the bobbin 2 coaxially with the central axis of the bobbin, and twisted. At times, the thread sent out from the bobbin 2 comes into contact with the tip of the protruding member 4,
A twisting mechanism capable of tension control, characterized in that the ballooning is wound up while being in contact with the inner peripheral surface of the ballooning regulating ring 5 to regulate the size of the ballooning. (3) The tip of the protruding member 4 is connected to the bobbin 2.
The twisting mechanism capable of tension control according to claim 1 or 2, characterized in that the twisting mechanism is capable of elastically deforming so as to retreat from the contact when it comes into contact with the yarn sent out from the yarn. (4) The tip of the protruding member 4 is normally elastically biased and in the protruding state, but when the bobbin 2
The twisting mechanism capable of tension control according to claim 1 or 2, wherein the twisting mechanism is capable of retracting so as to retreat from the contact when it comes into contact with the yarn being sent out from the yarn.
