摘要： A weft filament is inserted as a pick in a weft direction into a shed formed between groups of warp filaments extending and generally traveling in a warp direction, and is beaten into the warp filaments by a comb to form a woven textile. A defective pick is removed from the warp filaments by a system comprising at least one stripping nozzle directed generally upstream in the warp direction and connected to a supply that feeds compressed gas to the nozzle so the gas is expelled therefrom as a jet directed generally upstream in the warp direction over the defective pick to dislodge same from the warp filaments. The defective pick is then withdrawn in the weft direction from the shed after it is dislodged from the warp filaments by the nozzle.

摘要： In a loom a weft filament is fed from a supply and inserted in a weft direction through a warp so as to project from a downstream edge of the warp and the presence of the filament is detected by a sensor at the downstream edge. If no presence is detected, a deweaving device is operated that in a deweaving step strips the filament from the warp and ejects it therefrom past the sensor. A controller is connected to the sensor and loom for shutting down the loom when the sensor detects that no filament is ejected by the deweaver during and immediately after the deweaving step, shutting down the loom when the sensor detects a filament immediately after the deweaving step, and restarting the loom when the sensor detects a filament during but not immediately after the deweaving step.

摘要： This pneumatic supply device is designed for shuttle-free weaving machines with the picking of one or more weft threads (1, 2) by elements such as picking nozzles (5, 6) and nozzle relays (10), supplied with compressed air in accordance with predetermined sequences. A robot (25) connected to a picking sequence program support (26) drives, on one hand, electrovalves (12, 16) disposed in the compressed air inlets (13, 17) to the picking elements (5, 6, 10) and, on the other hand, switching members (20, 21) enabling these picking elements (5, 6, 10) to be supplied at at least two different pressures (P1, P2; p1, p2) selected as a function of the characteristics of the weft threads (1, 2) to be inserted. The switching members (20, 21) are, for example, proportional pressure reducers enabling the control of the air pressure in a tank (18, 22).

摘要： A weft filament is inserted in a loom by a mechanical shuttle from a feed side as a pick in a weft direction into a shed formed between groups of warp filaments extending and generally traveling in a warp direction. A deweaving system has a loosening nozzle for directing a jet of air against the defective pick in the warp direction for loosening the defective pick from the warp and at least one stripper nozzle situated between the groups of warp filaments for blowing the separated-out defective pick out of the warp against the weft direction to the feed side. A sensor is provided on the feed side for monitoring the pressure of the defective pick outside the shed on the feed side and a controller is connected to the stripping and loosener for, on detection of a defective pick, sequentially operating the loosening and stripper and then restarting the loom.

摘要： A shuttleless loom has an injection nozzle that is movable limitedly in the warp direction to one side of the warp and that has a filament-receiving upstream end and a filament-ejecting downstream end from which a weft filament is project in the weft direction through the warp. Separate generally stationary first and second yarn supplies to one side of the warp are associated with respective telescoping feed nozzles to the one side of the warp and each having a generally stationary upstream end and a downstream end displaceable between an advanced position relatively close to the injection nozzle and a retracted position relatively far from the injection nozzle. Respective actuators can displace the first and second nozzles between their positions and respective first and second feeders between the nozzles and the respective supplies supply filaments from the respective supplies to the upstream ends of the respective nozzles so that the respective filaments are ejected from the respective downstream ends thereof. A controller connected to the actuators switches the loom from the filament of one of the supplies to the filament of the other supply by displacing the downstream end of the telescoping nozzle of the other supply to the advanced position and then pneumatically blowing the respective filament from the downstream end of the nozzle of the other supply into the upstream end of the injection nozzle.

摘要： This device designed for weaving machines enabling a weft selection, comprises for each prefeed and measurement device (1), an electric drive motor (8) having a controlled angular position, such as a "step" motor. The angular position of the main shaft (14) of the weaving machine, detected by means of a coder wheel (24), is converted into pulses (D) which are supplied by a "switching system" (15) which may be switched from the weft selection control (16) to the electronic power circuit (17) associated with the motor (8) of the prefeed device (1) selected. It is therefore possible to drive the shaft (5) of the selected prefeed device through a predetermined number of rotations synchronously with the rotation of the main shaft (14) of the weaving machine.
