Toyoda's JAT 610 air jet loom offers smooth, high speed, vibration-free operation; low operating costs; and easy operation. It weaves denim, terry, wool, and glass based fabrics. Tapered subnozzles guarantee optimum filling yarn insertion conditions. The double filling yarn detectors prevent mispicks. The automatic fault alarm stops the loom if the presence of dirt or debris on the tunnel reed delays the filling yarn travel timing. The automatic timing control adjusts air injection timing to compensate for variations in filling yarn arrival timing. The electronic letoff mechanism and stop mark prevention system ensure superior fabric quality. Available auxiliary equipment includes mechanical or electronic takeup mechanisms ; jacquard, dobby, crank, negative cam, and positive cam shedding devices; and reflecting or penetrating type filling yarn detector stop motions.
