  • Patent number: 7269977
    Abstract: A floss blowing and heat dissipating apparatus for high speed circular knitting machines includes an annular duct located beneath a circular frame plate and an airflow generator to generate pressurized air. The annular duct has a passage inside and an air intake connector located thereon communicating with the passage, and a plurality of air vents close to a cylinder and straddle seats communicating with the passage. The airflow generator generates the pressurize air which is delivered to the air intake connector through an air directing hose so that the passage delivers the pressurized air to the air vents to eject the pressurized air forcefully towards the straddle seats, the cylinder and needles of a circular knitting machine where the floss is most likely to accumulate to carry away the floss. It also can reduce the temperature generated by the friction between needle troughs and needles to achieve optimal cooling effect.

  • Patent number: 7127920
    Abstract: A knitting machine for manufacturing plush fabrics includes latch-less cylinder needles in a cylinder, latch needles located on a needle dial and a cutting unit. The loop formed by a plush thread can be directly knitted in a fabric formed by ground threads to form a longer plush on the fabric surface. By changing the dimension of the needle dial, the interval of the peripheral edge of the needle dial and the cylinder needle can be increased so that the plush thread held on the hook of the cylinder needle can be stretched by the latch needle to become a longer loop. Finally, the loop is severed by the cutting unit to form a plush fabric of a longer plush.
