M7. Warp Stop Device
■
Warp stop device (dropper box)
The dropper box is located above the warp line in
the rear of a loom. If a warp is cut, the dropper drops
to energize a contact bar 3. The signal is transmitted
to the loom control box via a contact plate 4 and
cable 5 to stop the loom operation. In addition, a
towel weaving loom is provided with the dropper
boxes for the gland 6 and the pile 7 so as to indicate
which side of the yarn is broken.
