An outlet for the cover yarn that communicates with the lower end surface of the main shaft is provided on the outer periphery of the rotary disk, and a holder for holding a core yarn winding tube and a winding tube held in the holder are provided on the upper surface of the stationary disk. This is a covering device equipped with a rewind roller that rewinds the core yarn.
そしてこのカバーリング装置における静止盤は、その下
面に設けた永久磁石と不動盤の上面に設けた永久磁石と
の磁気力により主軸とともに回転しないような構造とな
っている。The stationary plate in this covering device has a structure such that it does not rotate together with the main shaft due to the magnetic force between a permanent magnet provided on the lower surface of the stationary plate and a permanent magnet provided on the upper surface of the stationary plate.

The results were not yet fully satisfactory in the following respects.

This causes severe wear on the bearing.

よりも一層経済的でかつ効率的なカバーリング装置を完
成したものである。As a result of repeated research day and night to improve the points (1) to (3) above, the inventors of the present invention found that although bearings suffer from large wear under thrust loads, it is economically advantageous to be strong against loads in the radial direction. Based on the above findings, by considering the mounting position of the magnets so that eddy currents do not occur on the rotary disk, and by creating a rotary disk with a structure that consumes less power, it is possible to create a cover that is more economical and efficient than conventional ones. This is a completed ring device.

ととなる。In addition, the rewinding roller, which is vertically rotatably installed on the stationary plate, is driven by a rotating magnet fitted on the Tekken rewinding roller and an external measurement of the stationary plate, and a cover is connected to the magnet on the rewinding roller. Because this is done by rotating rotating magnets that are mounted radially opposite each other across the thread path, eddy current loss occurs compared to the conventional method in which a rotating disk is interposed between the rotating magnets. This eliminates the restriction that the rotary disk itself must be made of non-conductive material.
従って回転盤はどんな材質でもよく、コストの低減化が
図れる上に、それだけ磁気的、電気的ロスがなくなると
いう利点がある。Therefore, the rotary disk may be made of any material, which has the advantage of reducing costs and eliminating magnetic and electrical losses.

ある。Furthermore, an advantage of this invention is that since it is not necessary to pass the cover thread through the thickness of the rotary disk, the rotary disk can be made thinner to that extent. Since there is no need to provide a bulky and heavy cylindrical body,
The weight of the rotary disk has been significantly reduced, allowing the rotary disk to rotate at high speed with far less power consumption than before, and air resistance against the rotary disk has been significantly reduced, resulting in less noise and improved noise control. It also has excellent effects.

装置。1. A stationary plate on which a vertically installed unwinding roller and a holder for holding a winding tube in pressure contact with the unwinding roller are vertically mounted is attached to a main shaft that is vertically bearing and rotates at high speed, through the bearing of the bearing. Among the magnets that are installed and restrict rotation through lines of magnetic force that act in the radial direction of the stationary plate,
If one magnet is installed on the periphery of the stationary disk, and the other magnet is placed on the outside of the stationary disk, at a position facing the one magnet across the path of the cover yarn, both of them will rotate to drive the rewinding roller. Among the magnets, one driven rotating magnet is fixed on the rewinding roller so as to rotate integrally with the rewinding roller on the stationary disk, and the other driving rotating magnet is located outside the stationary disk and is connected to the rewinding roller on the stationary disk. The magnet on the roller is provided so as to be opposed in the radial direction across the path of the cover yarn, and further a thin rotary disk provided integrally with the main shaft is located directly below the stationary disk,
A covering device characterized in that a cover yarn outlet is provided on the outer periphery of a small-diameter rotating base located on the back side of the rotating disk.
