Abstract: A water injection apparatus for a water jet loom, includes a weft insertion nozzle for weft insertion of a weft yarn by injection water, a weft insertion pump pumping water into the weft insertion nozzle, a water storage tank storing water introduced into the weft insertion pump, and a suction pipe passing water from the water storage tank into the weft insertion pump. The water injection apparatus includes an auxiliary water supply unit that is provided separately from the weft insertion pump and can supply water to the suction pipe. At least when the weft insertion pump sucks water, the auxiliary water supply unit supplies water to the suction pipe.

Abstract: A loom monitoring system includes loom computers and a host computer connected to the loom computers through a network. Each loom computer acquires a temporary IP address from a DHCP server when a fixed IP address is not set for the loom computer and requests the host computer to transmit a fixed IP address using the temporary IP address. The host computer assigns a fixed IP address to the loom computer that transmitted the assignment request signal and correlates the fixed IP address with a loom layout map. The loom computers each transmit an acquisition completion signal to the host computer using the fixed IP address in a designated order based on the loom layout map. The host computer correlates the fixed IP address of each loom computer with the loom layout map in accordance with the designated order.
