Abstract: Method for introducing a weft thread in an air weaving machine, wherein the instant when the supply of compressed air to a set or sets of auxiliary blowers is interrupted is controlled based on measurements on the transported weft thread during transport of this weft thread.

Abstract: A method and a clamping device for clamping a weft thread in a jet weaving machine are proposed. The weft thread strand runs through the beginning section (2.1) and the end section (2.2) of a mixing tube. The two sections between themselves form an engagement opening (8) and are connected with a first holding magnet (11) by a counter support (9). An actuator (6) in the form of an elastomeric bellows, which comprises a chamber (10), is located on the beginning section (2.1) of the mixing tube. The chamber (10) is connected to a valve (16) via a supply line (20) and is acted on variably with compressed air. By deformation of the actuator (6), a clamping element (7) connected thereto carries out a tilting movement between the counter support (9) and a contact stop part (19), which contains a second holding magnet (12). The holding magnets (11, 12) lead to an exact and reliable clamping of the weft thread (3).

Abstract: An apparatus (1) for the insertion of weft threads in a weaving machine is presented. The apparatus includes a nozzle holder (9) and, secured thereto, at least one nozzle (3) with a mixing tube (6) for the insertion of a weft thread (2) as well as a clamping device (7) which can be charged with a medium in order to firmly clamp a weft thread which is introduced into the nozzle. In addition the apparatus (1) contains at least one control valve (8) which is arranged at or in the nozzle holder (9) or nozzle (3) in order to control the clamping device (7).

Abstract: Weaving machine, method and selvedge forming apparatus for introducing into a shed an end (30A) of a weft thread (30) which has been inserted into a shed, the selvedge forming apparatus (4, 5, 6) being provided with a device (20) for introducing the end of the inserted weft thread into a subsequent shed, wherein the selvedge forming apparatus (4, 5, 6) includes a blowing device (50) having at least one blowing opening (51) which, in use, is positioned at the level of the plane of a selvedge (16, 17) of the woven fabric (2, 3), with the blowing device (50), blowing essentially toward the beat-up line (36) in a direction opposite to the direction of fabric movement.

Abstract: A device for inserting of weft threads in an air jet weaving machine comprising at least one set of main nozzles (13, 14) which are mounted in series, and to which individual regulating valves (21, 22) are assigned, is provided with a control and regulating unit (17) which defines the individual settings of the regulating valves (21, 22) with respect to one another, in order to form an overall value for the intensity of the impulse transmission of the set of main nozzles with each regulating valve contributing a proportion of the overall impulse intensity.

Abstract: A thread clamping device is provided for a jet weaving machine that has a main discharge nozzle (1) with a mixing tube (2) for inserting a weft thread (3) into a shed with a conveying fluid discharged from the main discharge nozzle. This clamping device is placed inside the mixing tube (2) in the area from which the weft thread exits, and has an actuator, which is situated outside of the mixing tube (2), and a lever connected to the actuator so that this lever is actuated by the actuator (6) to execute a tilting or pivoting motion whereby the weft thread is clamped between the lever and an abutment (9) in an opening of the mixing tube.

Abstract: The invention relates to a jet-weaving machine, particularly an air jet-weaving machine, which comprises a main discharge nozzle (1) with a mixing tube (2) for introducing a weft thread (3) into a shed by means of a conveying fluid discharged from the main discharge nozzle (1), and comprises a clamping device. This clamping device is placed inside the mixing tube (2) in the area from which the weft thread exits, and is provided with an actuator, which is situated outside of the mixing tube (2) and with a lever that is connected thereto in such a manner that this lever, when actuating the actuator (6) via an actuating means or when the actuation is stopped, executes a tilting motion whereby clamping the weft thread in an opening of the mixing tube between itself and an abutment (9).

Abstract: A weft end recovery apparatus comprises weft end carrier for carrying by water flow weft ends formed as a result of weft insertion, a plurality of storing and dewatering sections to receive the weft ends carried from the weft end carrier together with the water, and switching mechanism for selectively switching the storing and dewatering sections to store the weft ends and the water from the weft end carrier.

Abstract: A tack-in apparatus is provided wherein injection ports are arranged at upper and lower sides of a weft yarn path, respectively. The injection ports inject currents for folding back an end portion of a cut weft yarn into a warp yarn opening on the weft yarn path which the weft yarn passes by a beating operation. Air guides projecting toward the warp yarn opening are formed at circumferential portions of the injection ports between the weft yarn path and the injection ports. The surfaces of the air guides which are on the sides of the injection ports are inclined toward the weft yarn path at front end portions of the air guides. In order to tack in the weft yarn end, the injection air currents are directed to the central portion of the warp yarn opening. This enables the weft yarn end to be transferred reliably, the tack-in operation to be carried out reliably, and the turbulence of the warp yarn to be reduced.

Abstract: A solenoid valve, particularly for use in air nozzle weaving machines, has a valve housing with at least one valve inlet and at least one valve outlet. An electromagnetically actuated valve body is arranged in a passage area between the valve inlet and the valve outlet. In order to permit a fast and operationally reliable exchange of the parts of the solenoid valve subjected to wear, it is provided that a fastening flange, the valve body, as well as the electromagnetic drive together form a first valve subassembly which is subjected to a rapid exchange. The valve housing with its connections forms a second valve subassembly which is fixedly arranged on the machine.

Abstract: A filling insertion system for a weaving machine includes a holder (8) for at least two nozzles (10, 11, 50). Each of the nozzles (10, 11, 50) includes a feed connection (20, 21, 52) for a pressurized fluid. The feed connections (20, 21, 52) are all arranged on the same side (15) of the holder (8) and are space apart from each other along the direction of the longitudinal axes (30, 31, 54) of the nozzles (10, 11, 50).
