摘要： The invention relates to a method for the taut-holding of the weft thread (15) in the mixing tube (4) of the main nozzle (1) of an air jet loom, and an air jet loom for the carrying out of the method. The invention has the underlying technical object of avoiding an air stream effective over nearly the total length of the main nozzle (1) and disadvantageously influencing the structure of the weft thread (5) during its idle phase in the main nozzle (1), and nonetheless holding the weft thread (5) taut in the main nozzle (1). This is achieved in that the air stream, during the idle phase of the weft thread (5), impinges on only its front end (5a) in the mixing tube of the main nozzle.

摘要： A weft thread insertion device for an air jet loom includes a nozzle block mounted on a sley to be movable together therewith. The movable block has a plurality of individual nozzles. Devices supply compressed air to the nozzle block by way of one or more stationary distributor blocks. At least one outlet is associated with the distributor block. Compressed air is supplied through respective flexible pressure lines from the respective outlets to respective inlets of the individual nozzles of the nozzle block. In order to supply air using short pressure lines that do not intersect, the invention provides that the distributor block or blocks so arranged that they at least partially surround nozzle block regardless of the position of the reed.

摘要： A weaving machine contains a reed (8) and a weft thread guide apparatus (32) which are connected to one another and are pivotal between an insertion position and a beat-up position. For the insertion of a weft thread, a weft insertion apparatus (14) which is arranged in a fixed spatial position and has at least one blower nozzle (22) for the insertion of a weft thread (38) into the guide passage (36), a thread clamp (16) and a shear (15) are provided. Coupled to the reed are the thread clamp in order to clamp an inserted weft thread (38) and to forward it synchronously with the guide passage (36) from the insertion point up to the abutment point, and the shear (15), with the shear (15) being placed after the thread clamp (16) in the beat-up direction in order to sever off the weft thread immediately after the clamping. Through the arrangement of the insertion apparatus in a fixed position and the functional association of the thread clamp and the shear with the reed, the control is simplified so that up to sixteen weft threads of differing kinds and colors can be inserted.

摘要： A blow device for weft threads in weaving machines, in particular a blow device which makes use of a nozzle of the type which consists of a housing, a thread guide duct extending through the housing and a first or main blower situated in the housing and working with the thread guide duct to transport a weft thread to the shed of the weaving machine. The nozzle has a second or threading blower also situated in the housing that cooperates with the thread guide duct for threading the nozzle. The second blower has at least one blow duct which intersects the thread guide duct at an angle so as to thrust a weft thread presented at the entry of the thread guide duct through the thread guide duct when supplied with air. A central system deactivates the main blower when the threading blower is activated.

摘要： In a weaving machine, one of the guiding elements used to normally guide a weft thread between a thread preparation mechanism and the shed of the weaving machine is made moveable. The moveable guiding element may, for example, be an auxiliary weft insertion nozzle and can be used in place of supplemental threading and guiding mechanisms for such as purposes as retrieving a broken weft thread for automatic rethreading or extracting a defective weft thread from the shed.

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： Disclosed herein are apparatus and method of multi-shed weaving wherein a weft thread is inserted into a retained shed by a fluid jet. The movement of the fluid jet can be synchronized with the movement of the retained shed. The shed may be retained by a shed-retaining member or members adapted to removably receive one of the weft threads. A device is also disclosed for spreading apart the wrap threads to facilitate the insertion of the shed-retaining members into an open shed prior to its retention.

摘要： The nozzle structure has a control valve in which a channel for the admission of air opens at an acute angle into the guide channel for a weft thread for a weaving machine. The channel can be adjusted so that the admitted air is directed for deceleration of the thread counter to the insertion direction. The control valve can be rotated 180.degree. so that the admission channel is in an opposite position so that the admitted air then flows in the insertion direction of the weft thread and can be used for threading a broken weft thread into the nozzle structure.

摘要： The filaments in a weft thread or yarn in a pneumatic loom are tangled and consolidated to prevent untangling of the weft thread when it is transported, after the tangling, through the weft insertion channel in a loom shed. For this purpose the leading end of the weft thread is temporarily stopped in a weft insertion nozzle pipe by a first air stream the so-called holding air stream (19) with a first pressure (P1) between two weaving cycles following each other for holding the weft thread stretched. At the same time a second air stream (20) having a higher pressure (P2) than the first pressure (P1) and a different flow direction than the first air stream (19) is applied to or along a leading end portion of the weft thread for tangling the filaments and thereby locking or consolidating the filaments in the weft thread. Each weft insertion nozzle pipe has a first port and a second port through which the first and second air streams are introduced into the weft insertion the nozzle pipe. The second port is positioned downstream of the first port and closer to a free exit end (15) of the respective weft insertion nozzle pipe but still spaced from the free exit end.
