FORMATION OF TWISTED SELVAGE USING TWISTED SELVAGE FORMER

Japanese Patent JP2933889

B2

PROBLEM TO BE SOLVED: To enable the omission of a driver for a twisted yarn bobbin holder and make another driving unit for winding the twisted yarn unnecessary by allowing a twisting disk having two eye holes for guiding the yarns to be twisted bored to rotate in one direction, then rotate in the reverse direction.
SOLUTION: A twisting disk 7 having two eye holes 7b, 7c for guiding yarns to be twisted 11, 12 bored is driven through 2-1 driving belt by a driving wheel 5. The twisting disk is rotated in one direction, then twisted in the reverse direction to remove the twists or entanglement of the twisted yarn caused by the one-way rotation of the twisting disk on the way between the twisted yarn bobbin and the twisting disk. A servomotor 20 is used as a driver for the disk 7 and the rotation of the twisting disk 7 can be turned reversely every weft yarn.
