Abstract
A jet loom includes a main jet nozzle for launching a weft thread into a shed, and a plurality of auxiliary jet nozzles successively operated to assist the weft in being transported through the shed by the jet of air injected from the main jet nozzle. The auxiliary jet nozzles are operated to simultaneously discharge the air at least one or more times during a period of time necessary to complete one weft inserting operation.
Claims8
A method for inserting a weft thread through a shed of a jet loom, said method comprising:
- launching a weft thread by a fluid jet from a main jet nozzle, and thereby initiating insertion of said weft thread through a shed;
- successively and sequentially discharging fluid jets from auxiliary jet nozzles spaced along the path of said weft thread through said shed, and thereby assisting said main jet nozzle in inserting said weft thread through said shed;
- and
- at least once during the period of time necessary to complete a weft thread insertion operation, simultaneously discharging fluid jets from all of said auxiliary jet nozzles.
An apparatus for inserting a weft thread through a shed of a jet loom, said apparatus comprising:
- main jet nozzle means, adapted to be positioned adjacent an inlet of a shed of a jet loom, for emitting a fluid jet for launching a weft thread, and for thereby initiating insertion of said weft thread through said shed;
- a plurality of auxiliary jet nozzles adapted to be spaced along the path of said weft thread through said shed;
- first fluid supply means, connected to said axuiliary jet nozzles, for successively and sequentially discharging fluid jets from said auxiliary jet nozzles and for thereby assisting said main jet nozzle means in inserting said weft thread through said shed;
- and
- second fluid supply means, connected to said auxiliary jet nozzles, for simultaneously discharging fluid jets from all of said auxiliary jet nozzles.
