The process of using air to insert filling yarn into the warp shed during weaving.

The package containing the filling yarn, often a cone or cheese, for weaving.

A device that holds and supports the supply package (cone) for yarn delivery.

A component that feeds yarn from the supply package to the weaving machine nozzle.

A device on the pre-winder that controls the amount of yarn stored for weaving.

A device on the pre-winder that senses the yarn windings and controls the winding/unwinding process.

A component that regulates the tension of the yarn as it unwinds from the cone.

The distance the filling yarn travels across the width of the fabric.

A system that ensures continuous weft yarn supply, vibrates to detect supply, stops the loom on yarn breaks, and smoothens yarn tension.

Feeds yarn to a tandom nozzle; number depends on pre-winders; crucial alignment for avoiding breakage.

Blows weft yarn during picking; fixed on sley, moves with reed; needs correct distance from weft cutter.

Assist main nozzle, fitted on sley, arranged in groups; air pressure increases from left to right; regulated by solenoid valves.

Yarn breakage in a weaving process

Control air pressure to sub-nozzles; Each controls a group of needles.

The number of main and tandom nozzles matches; it depends on the number of pre-winders

The second sensor in a weaving machine that detects the presence or absence of weft yarn. It stops the machine if weft yarn reaches the sensor, ensuring proper yarn feed and preventing yarn breaks.

Nozzles in a weaving machine that ensure the weft yarn is stretched during the shedding process. They help maintain a consistent weft yarn tension for smooth weaving.

A reed with grooves that guide the weft yarn from the picker to the receiving side during weaving. It creates a path for the yarn to travel smoothly and prevents snags.

Devices that hold and stretch the fabric during weaving on both sides. They ensure a consistent and even fabric width.

Temples used for light-weight fabrics, providing gentle support.

A situation where the flow of air through the sub-nozzles is restricted, leading to insufficient weft yarn insertion and potential weft breakage.

The distance between two consecutive sub-nozzles on an air-jet weaving machine, which varies to compensate for air pressure changes.

To control the amount of air flow to the sub-nozzles, regulating the air pressure and yarn insertion process.

A device responsible for cutting the weft yarn after insertion, leaving a short length of weft on the selvedge.

A cutter located on the receiving side of the air-jet loom, used to separate and remove waste yarn from the leno fabric.

Synthetic yarns used to grip and hold the weft waste on the receiving side of the air-jet loom.

Sensors located on the receiving side of the air-jet loom that detect the presence of weft yarn and ensure proper weft insertion.

The condition of the cutters directly affects the quality of the fabric by influencing the accuracy of the weft cut and the appearance of the selvedges.
