摘要:
A method and apparatus is provided for manufacturing a carbon fiber woven fabric by opening and closing a warp sheet formed of carbon fiber warps and by injecting wefts made of carbon fibers by water-jet into the warp sheet when the warp sheet is open. The accumulation of fluffs generated by abrasion between the weft and various guides is reduced by interrupting dispersion of water injected from the nozzle onto the weft as the weft travels from a bobbin to the nozzle, by sucking fluffs from the weft, and/or by causing contact between the weft and fluffs on the surface of the nozzle by loosening the weft, thereby making it possible to conduct a high-speed continuous operation.

A device for use in a weaving machine to eliminate accumulations of floating fibers by generating pulses of pressurized air has a storage vessel for pressurized air. The storage vessel is connected to an air compressor via a throttle and a valve disposed between the throttle and the storage vessel. The valve has a passage, a first conduit branching from the passage to the storage vessel, a second conduit branching from the passage to the throttle and air compressor, and a third conduit branching from the passage to a nozzle which can be directed onto the weaving machine. A valving element is movable in the passage between a first position in which the first conduit communicates with the second conduit but is sealed from the third conduit and a second position in which the first conduit communicates with the third conduit but is sealed from the second conduit.

A device for the removal of dust from parts protecting weaving machine components from weaving dust includes a dust screen, a number of freely movable blowing tubes which direct air from their open ends into an area adjacent the dust screen, and blowing devices for feeding air through the tubes. Removed dust is disposed of by a separate device such as a suction nozzle.

Method and apparatus to clean the reeds of a weaving machine without removing the reeds from the machine and without disconnecting the warp yarns. A cleaning head is slid down the reed and blows a foaming agent through the space between the dents of the reed and sucks the lint, dust, etc. dislodged by the foaming agent back through the spaces between the dents and directs such to a point of collection.

An automatic cleaning apparatus is provided for a plurality of weaving machines. The cleaning apparatus includes a powered vehicle on which robot arms are mounted for programmed movement into various designated areas of a weaving machine. Each arm is provided with a coupling to permit coupling to a suction nozzle or blowing nozzle which can be stored within the apparatus. Deliberate individual cleaning operations can be performed on particular units of the weaving machine at particular times or in accordance with instructions received from a weaving machine.
摘要:
A device for preventing dust deposits on weft feeders for weaving looms--of the type wherein the amount of weft yarn being drawn from a reserve wound on a drum of the feeder, to be fed to the loom, is reckoned by a detecting unit--comprises nozzles for blowing blasts of air between the detecting unit and the drum.
摘要:
The weaving machine is provided with an air conditioning system which delivers air upwardly from the floor between the heddles and cloth beam. The conditioning system uses a covering over the air outlets which has a plurality of outlet openings for passing a plurality of thin and gentle jets of air into the space between the heddles and cloth beam. The fine outlet openings are sized with dimensions less than 1 millimeter.

A sequential cleaning device for a loom ensures sequential cleaning by blowing compressed air or possibly by suction, at various points of a loom. The device comprises, upstream of a utilization circuit leading to various points to be cleaned, a pneumatic control circuit connected to a compressed air inlet. The circuit comprises, in a main pneumatic line a first distributor which is normally closed, and controlled mechanically and a second distributor which is normally open and controlled pneumatically. Controlling the opening of the first distributor may be effected by a rotary member forming a cam of the loom. Controlling the closure of the second distributor is ensured by a branch supply line in which pneumatic delay means are incorporated.

The cleaning means employs a nozzle on one side of the picking mechanism which directs a stream of air over the weft yarn in a direction opposite the picking direction to pass through the picking station as well as a funnel on the opposite side of the picking mechanism to receive and exhaust the air with any entrained foreign matter from the picking station.

In a weaving loom including a selvage yarn feeding device usually including a pair of yarn feeding units mounted on and driven by a planetary gear mechanism and each having a yarn guide area in which a selvage yarn being passed therethrough is scraped against various edge portions and thus tend to produce fibrous flues, an apparatus for removing such flues from the yarn guide area of each yarn feeding unit, comprising air-flow inducing means such as flue blow-off means or flue collecting means or a combination of both and valve means which is actuated in cycles synchronized with weaving cycles of the loom so that compressed air is discharged from the flue blow-off means into the yarn guide area and/or suction is developed in the yarn guide area by the flue collecting means whereby the flues deposited in the yarn guide area are splashed therefrom and, if the flue collecting means.
