Claims (1)

[Scope of utility model registration request] The warp yarn 2 supplied from the creel is transferred to the circular loom 1.
In this device, a plurality of feed rollers 14 are arranged in an annular manner at the lower part of the outer periphery of the annular loom 1, and the group of feed rollers 14 are integrally rotated at a constant speed by a universal joint 15. The feed roller 14 is connected in an annular manner and
The group is driven by a motor 16, and each feed roller 14
first and second guide rollers 17,
18 is provided, and the warp yarn 2 supplied from the creel is passed through the first guide roller 17 and the feed roller 1.
4 and the second guide roller 18, the warp yarns 2 are fed to the annular loom 1, and the warp yarns 2 are actively fed by the rotation of the feed roller 14, and the warp yarns 2 are fed to the first feed roller 14 in the group of feed rollers 14. In place of the accompanying second guide roller 18, a detection roller 20 is provided which is swingable in a direction towards and away from the feed roller 14, and is wound around the first feed roller 14 from the swinging position of the detection roller 20. detecting the average tension of the two groups of warp yarns, and controlling the rotation speed of the motor 16 based on the value of the tension;
Warp threads 2 wrapped around the feed rollers 14 group
An active warp supply device for a circular loom, characterized in that the warp yarns 2 are actively supplied to the circular loom 1 while maintaining the tension of the group constant.
