8, the surface at the position of the mounting holes 100, 101 is the belt transmission means 2
It functions as a mounting portion 60 for the No. 5. Further, it is desirable that the cables of the sensors be extended along the plate surface, but the side plate 29 is formed with a string locking hole 102 for passing a string (not shown) for bundling the side plate 29 ( (See FIG. 1).

As described above, since the plate members (28 ... 32) bent by sheet metal processing are assembled to form the case 27 for accommodating and supporting the power transmission mechanism 21, it is stronger and lighter than the conventional angle member case. The double twister has high durability and reliability. In addition, the mono bolt 42 that fastens and fixes each plate material,
Since the case 27 can be easily assembled only by inserting it from one side, the assembly work can be facilitated in a short time. Further, automation of the member manufacturing process can be relatively easy. Then, the bent portions 34, 33 of the middle plate 32 and the lower plate 28, and the surfaces of the side plate 29 and the box plate 30 are made to function as mounting portions 49, 55, 60 for the respective components of the power transmission mechanism 21. As a result, no separate mounting plate or bracket is required, and the number of parts can be greatly reduced. That is, reduction in manufacturing cost is achieved. And assembling holes 35, 36, 44
The bearing holes 95, ..., 98 and the like can be opened in advance before assembly, and there is no room for error in the mutual positional relationship, and the assembling accuracy is improved. The belt transmission means 25
Since the box is housed inside the box plate 30 in a hermetically sealed manner, it is possible to prevent the lubricating oil from scattering due to the rotation of the pulley. Furthermore, since no residual material is produced during plate removal, it is possible to reduce the number of steps involved in processing the residual material, and to achieve further cost reduction. Although illustration is omitted, it is preferable that the motor end box provided at the end of the weight row on the opposite side of the case 27 is also made of a metal plate having a U-shaped cross section and assembled with monobolts.

Further, in the present embodiment, the power transmission mechanism 2
1, a belt transmission means 25 is provided, and the continuously variable pulley 6
Since the rotational speed can be controlled freely by means of No. 1, there is no need to replace the speed change gear in the conventional mechanism including the gear train, and more speedy and fine twist number control can be performed. The assembly of the belt transmission means 25 can be performed accurately and easily.

The power transmission mechanism 21 is the belt transmission means 2
Although it has been described as having the gear No. 5, it is naturally possible to accommodate and support the power transmission mechanism constituted by the gear train. Further, although the double twister composed of the two-stage weights is shown in this embodiment, the present invention can be similarly applied to the single-stage double twister. Further, the present invention is not limited to the double twister, but can be widely applied to textile machines having a drive / transmission mechanism at the ends of the weight row.
