BEST MODE FOR CARRYING OUT THE INVENTION A first embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

FIG. 1 schematically shows a side view of the entire loom.
M is a loom drive motor capable of forward and reverse rotations, and the loom drive motor M is controlled by the loom control computer C. 1
Reference numeral 1 denotes a feed motor that is independent of the loom drive motor M and is capable of forward and reverse rotation. The feed motor 11 is a warp beam 1
Drive 2 The warp T sent out from the warp beam 12 is passed through the heddle 15 and the reed 16 through the back roller 13 and the tension roller 14. The woven cloth W is wound around the cross roller 21 via the expansion bar 17, the surface roller 18, the press roller 19, and the cross guide bar 20. The surface roller 18 cooperates with the press roller 19 to draw the woven cloth W toward the cross roller 21.

The tension roller 14 is attached to one end of the tension lever 22 and
Tension is applied to the warp T by a tension spring 23 attached to the lower end of the warp 2. The tension lever 22 is rotatably supported at one end of a detection lever 24, and a load cell 25 is connected to the other end of the detection lever 24. The warp tension is transmitted to the load cell 25 via the tension roller 14, the tension lever 22 and the detection lever 24. The load cell 25 outputs an electric signal corresponding to the warp tension to the loom control computer C. The loom control computer C controls the rotation speed of the feed motor 11 based on the tension detection information obtained from the load cell 25. The warp tension at the time of weaving is controlled by this rotation speed control, and the generation of a weft bar during weaving is prevented.

The main shaft 26 of the loom is directly connected to the loom drive motor M. A driven gear 27 is fixed to the main shaft 26, and a gear 28 is meshed with the driven gear 27. The gear 28 is fixed to the driven shaft 29, and the driven shaft 29 is rotatably supported by the machine frame 30. The main shaft 26 and the driven shaft 29 are always covered with a cover 31 as shown in FIG.

The driven gear 32 is fixed to the roller shaft 181 of the surface roller 18. As shown in FIG. 2A, a gear 33 is meshed with the driven gear 32. The gear 33 is fixed to the driven shaft 34, and the driven shaft 34 is rotatably supported by the machine frame 30. Driven gear 3
2 is connected to a loom drive motor M via a reduction gear mechanism (not shown) and a clutch (not shown). The gear 33 and the driven shaft 34 are covered with a cover 50.

As shown in FIGS. 2A and 2B, the tip ends of the driven shafts 29 and 34 are formed into small diameter portions 291, 341, and the small diameter portions 291, 341 have keys 351 and 352.
Is fixed. Reference numeral 37 shown in FIGS. 2A and 2B is the same handwheel. As shown in FIG. 2C, a fitting hole 371 is formed in the radial center portion of the hand-turning handle 37, and a key groove 372 is formed on the inner peripheral surface of the fitting hole 371.

Since the turning operation of the surface roller 18 and the turning operation of the main shaft 26 can be performed by one hand-turning handle 37, it is advantageous in terms of cost as compared with the case where the driven shafts 29 and 34 of each turning operation mechanism are separately used by different hand-turning handles. Is. (1-2) Since the driven shaft 29 connected to the main shaft 26 via the gears 28 and 27 rotates at a high speed, it is not preferable in terms of safety that the handwheel 37 is always attached to the driven shaft 29. However, the rotation of the driven shaft 34 connected to the surface roller 18 via the gears 32 and 33 is extremely slow, and there is no problem even if the handwheel 37 is always attached to the driven shaft 34. Handwheel 3 on the driven shaft 34
If 7 is always attached, the main shaft 26 of this loom
It is easy to prepare the hand-turning handle 37 for the turning operation. (1-3) To remove the handle 37 from the driven shafts 29, 34 by loosening the set screw 38, loosen the set screw 38.
