摘要： The invention aims at equalizing weft time differences when launching successive threads and thereby obtaining a more uniform cloth. For that purpose the thread velocity in the initial phase of the weft is measured and on the basis thereof an additional pressure impulse of the conveying fluid may be supplied to the thread. According to a different possibility, in dependence on the measured value, the thread is more or less braked by means of a brake at the end of the weft phase.

摘要： An air supply system for a pneumatic loom contains a pressurized or compressed air container connected by means of a primary valve with a pressure line or conduit. There are also provided a primary blowing nozzle and auxiliary blowing nozzles connected by means of a respective control valve with the compressed air container or reservoir. There is further provided a compressed air storage which, during standstill of the loom or weaving machine, is connected with the pressure line or conduit and, during the starting phase of the loom, is connected forwardly of the pressurized or compressed air container. In this way upon start-up of the loom the compressed air container is supplied with compressed or pressurized air by the compressed air storage, causing an extremely rapid build-up of pressure in the compressed air container.

摘要： A supply channel for the thread has its exit end surrounded by an annular orifice. A connection is provided for supplying a flowing pressurized fluid to the upstream side of the orifice, and an elongated mixing tube is arranged to receive the thread as well as fluid discharged from said orifice and substantially forms an extension of said channel. A sleeve surrounds only the outflow end portion of the mixing tube, the upstream end of the sleeve having a sealing engagement around the mixing tube, and the downstream end of the sleeve lying in substantially the same plane as the downstream end of the mixing tube. A sleeve-shaped filling piece fills the space between the downstream end portion of the sleeve and the mixing tube and contains axial exhaust channels. A connection is provided for supplying a flowing pressurized fluid to the interior of the sleeve upstream of the filling piece.

摘要： The transport of a flexible thread is effected by means of an injector for inserting a weft thread into a weaving mechine. In order to therewith keep the air consumption as low as possible the diameter of the discharge tube is made as small as possible. For nevertheless increasing the force imparted to the thread and thereby its directional stability the invention uses with an injector for subsonic inlet flow of the gas a discharge tube which widens along a very small conical angle, such that over its full length the gas obtains the speed of sound. With an injector for supersonic flow of the inlet gas this supersonic velocity is maintained along the full length of the discharge tube likewise by widening the discharge tube along a very small conical angle.The directional stability of the thread is further increased if, by keeping constant the cross-sectional area of the discharge tube, it is flattened in the direction perpendicular to the plane of the warp threads.

摘要： An air supply system for a pneumatic loom contains a primary or main nozzle and a number of auxiliary nozzles. A pressurized or compressed air container or reservoir is connected by means of a primary or main control valve with a pressure line or conduit. The auxiliary nozzles are connected with the compressed air container. The primary nozzle is connected by a line with the primary control valve. This line extends, in the direction of the primary nozzle, through a pressure regulation valve and a control valve. Directly forwardly of the control valve there is arranged a compressed air storage. Consequently, there is obtained the beneficial result that the pressure in the primary nozzle, each time that the loom is placed into operation, always reaches its operating value as rapidly as possible. Thus, it is possible to dispense with the need to increase such pressure and the weft thread or filling is therefore less markedly loaded.

摘要： In the weft insertion nozzle arrangement containing at least two weft insertion nozzles the mixing tube of one weft insertion nozzle is set with its outflow or discharge end of end region parallel to a weft insertion line. The outflow or discharge end or end region of the mixing tube associated with the other weft insertion nozzle is set at a small angle of about 3.degree. relative to the weft insertion line. The entire weft insertion nozzle arrangement is fixedly mounted at a weaving machine member carrying such weft insertion nozzle arrangement. Movable control members for displacing the weft insertion nozzles and faulty operations associated therewith are thus eliminated. Tests have shown that the weft insertion can be reliably accomplished even when the mixing tube of the other weft insertion nozzle is set at such small angle of inclination relative to the weft insertion line.

摘要： A method for inserting a measured weft thread length by means of a blowing nozzle, in which the transport air jet at the end of the weaving shed remote from said nozzle is deviated together with the thread length end through an angle relative to the insert direction and is entered into a mixing tube by means of an auxiliary air jet. The invention aims at having the auxiliary air jet acting substantially only for stretching the thread directly beside the cloth edge. This is achieved in that the auxiliary air jet is supplied as a concentrated jet centrally into the deviating transport air jet.
