Embodiment Construction
[0021] figure 1 The shown, known prior art warp stop device slat according to EP1098025 has a plurality of warp stop devices for monitoring the thread tension at a plurality of embroidery points such as a shuttle embroidery machine. Each broken warp self-stop device has a switch warp stop piece 13 that can turn around the axle 11, and it is made of wire and has two lever arms 15,17. An eyelet 19 for receiving a face yarn is provided on the lever arm 15 . A spring 21 acts on the lever arm 17, and it will make the switch stop piece 13 enter the position shown in the figure together with the gravity acting on it, where the lever arm 17 contacts the contact rail 18. Thus a fault signal is generated to indicate a broken yarn. Usually, when the embroidery machine is working, the tension in the face yarn 14 will raise the switch warp stop piece, as figure 2 Contact with the contact rail 18 is thus prevented, as indicated by the dotted line in the center.
