(4) Warp tension detection method in which the displacement of the breast beam due to the fabric tension applied to the breast beam of the loom is detected by load sensors attached to several locations on the back of the breast beam, (5) 41 breast beams Displacement of the breast beam due to the fabric tension applied to the beam. A warp tension detection method that detects fabric tension using a load sensor attached to the support shaft where the entire breast beam is displaced. (6) The displacement of the breast beam due to the fabric tension applied to the breast beam of the loom is detected by the displacement load sensor of the breast beam, and the detection signal from the load sensor and the tension are sent to the control unit of the drive motor of the warp delivery device.

り付けられる．This woven fabric 7 is wound onto a cross roller 11 via a breast beam 8, a surf roller 9, and a guide roller 10. The sending device 100 of the warp roller 1 is
The rotational torque of the drive motor M is applied to the worm 13, worm wheel 14. The deceleration is transmitted via the gear 15 to the gear l2 which is directly connected to the warp roller l. The controller C automatically controls the rotational speed of the drive motor M at a predetermined speed at which the warp group 2 is sent out based on the tension set by the tension setting device S. The rotation speed of the drive motor M is calculated by the controller C based on the magnitude of the tension signal from the warp tension load sensor LS according to the present invention and the set tension of the tension setting device S, and the controller C sends out the warp group 2 at a predetermined speed. The rotational speed of the motor drive motor M is automatically controlled by feeding it back with the encoder E. On the other hand, the winding device 200 of the cross roller l1. It has a known configuration and winds up the woven fabric at a feeding speed that is synchronized with the winding speed. Next, an example of installing the warp tension load sensor LS according to the present invention will be explained. (First embodiment) The breast beam 8 is strung around a plurality of support columns l8, and each base is connected to a support shaft 19 with a boss 20It.
It is fixedly installed through the A load sensor LS is embedded inside the center of the breast beam 8 as shown in FIG. ．． (Second Embodiment) At the center of the breast beam 8 where the maximum strain occurs, a load sensor LS is attached to one support column 18 as shown in FIG.
The displacement of the breast beam due to fabric tension is detected with high sensitivity. (Third Embodiment) Furthermore, as shown in FIG.
The fabric tension is detected by these sensors. (Fourth Embodiment) Also, as shown in FIG. 1. Displacement of the breast beam due to fabric tension applied to the breast beam of a loom. The detection side l9a attached to the boss 20 of the support shaft 1'9, where the average displacement of the entire breast beam occurs, is detected by a load sensor to detect the fabric tension. It is configured to detect. ``Effects'' As described above, the present invention has each load sensor detect the fabric tension of the fabric applied to the breast beam that is close to the fabric front B. Accurate warp tension can be detected in an ideal detection environment that minimizes warp tension fluctuations due to the beating movement of the loom, and warp thread delivery is achieved by accurately detecting warp tension in the weaving front area, which directly affects the weaving row. It has the effect of controlling the control device and making it possible to weave elegant fabrics. Furthermore, each load sensor is mounted on the breast beam close to the Orimae in a space-saving manner.
