Abstract: A power loom includes a frame, a plurality of warps, a weft spool, a plurality of wefts, and a speed adjustment device. The speed adjustment device includes a support rack, a rotation shaft, a drive motor, a sensor, a press member, and a press rod. Thus, when the output speed of the wefts is gradually reduced to a preset value, the wefts are tensioned and moved upward, and the press member is moved upward to touch the sensor which sends a signal to actuate the drive motor which increases the rotation speed of the rotation shaft and the weft spool to increase the output speed of the wefts largely so that the wefts can be pulled outward from the weft spool quickly to prevent the wefts from being torn or broken due to an excessive pulling force.

Abstract: A weft end treating device for a shuttleless loom comprises a yarn holding device which holds the free end of an inserted weft and tensions the weft in synchronism with the beating motion, and pushing dents for pushing the free end of the weft into the yarn holding device when the weft is beaten up. The yarn holding device is fixedly mounted on the frame of a loom at a position on the extension line of the cloth fell on the weft arriving side. The pushing dents are fixedly provided on the sley, of the loom opposite to the yarn holding device.

Abstract: A filling thread stop motion device for a loom which, upon failure of delivery of a filling thread during the weaving operation, the device shuts down the loom.
