Abstract (en)

A yarn feeding plate double-sided floss blowing apparatus for circular knitting machines is installed in a circular knitting machine (10) which includes a needle cylinder (50) to hold a plurality of knitting needles (51) and yarn feeding plates (40). The floss blowing apparatus (10) comprises an air blowing unit (12). The air blowing unit (12) includes a first air blowing duct (121) and a second air blowing duct (123). The first air blowing duct (121) has one end extended above the yarn feeding plates (40) and bent towards a lower half portion of an outer side (44) of the yarn feeding plates (40) to form a first air ejection nozzle (122). The second air blowing duct (123) has one end extended close to a lower half portion of an inner side (45) of the yarn feeding plates (40) and above the knitting needles (51) to form a second air ejection nozzle (124). Thus strong airflow can blow away the floss on the yarn feeding plates (40) at the shortest distance.
