Floss blowing and heat dissipating apparatus for high speed circular knitting machines

A floss blowing and heat dissipating apparatus for a high speed circular knitting machine which has a cylinder rotating about a center spindle, the cylinder having a plurality of needle troughs to hold respectively a needle or a sinker, and being surrounded by a circular frame plate mounted onto a frame plate bracket and a plurality of straddle seats mounted onto a horizontal frame plate, each of the straddle seats having a cam to drive the needle up and down while the cylinder rotates to perform knitting operation, the floss blowing and heat dissipating apparatus comprising:

• an airflow generator to generate pressurized air which is delivered through an air directing hose;
• a plurality of annular ducts which are located on the periphery of the cylinder and the straddle seats and have a passage which has two open ends, and have a plurality of air vents on the annular ducts close to the cylinder and the straddle seats communicating with the passage;
• and
• a plurality of connection ducts bridging the annular ducts and communicating with the passage;
• wherein the pressurized air is ejected through the air vents to blow forcefully towards the straddle seats, the cylinder and the needle to carry away floss and heat accumulating thereon.

• an annular duct located beneath the circular frame plate;
• and
• an airflow generator to generate pressurized air;
• wherein the annular duct has a passage inside and an air inlet formed thereon communicating with the passage, and a plurality of air vents close to the cylinder and the straddle seats that communicate with the passage;
• the airflow generator generating pressurized air which is delivered to the air inlet 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 the needle to carry away floss and heat accumulating thereon.
