  • Patent number: 4346504
    Abstract: An improved fluid operated forwarding and drawing apparatus for continuous filamentary materials including a jet nozzle structure defined by a fluid outlet port from a fluid plenum chamber and a filament guide tube where the nozzle has a converging acceleration zone, a throat, a diverging expansion zone and a converging transition zone. A small diameter friction tube abuts an exit to the transition zone. The device is adjustable during set up and operation whereby close manufacturing tolerances are not required and operating parameters of the nozzle may be easily varied. The device is operable at low air pressures, low air consumption and low noise levels while handling filamentary materials at high linear velocities. A process for drawing and forwarding filamentary materials is also disclosed.
