Abstract:
1. 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, each of needle troughs holding 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 at least one air intake connector bridging the annular ducts and having an air inlet to channel the pressurized air to 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.
