ABSTRACT:
A circular knitting machine having an integrated multiple yarn changing apparatus comprises a first yarn changing apparatus, a second yarn changing apparatus, and a driving cam set. The first and second yarn changing apparatus include respectively at least one yarn feeding means which is moved outwards through a first yarn feeding stroke and a second yarn feeding stroke to a yarn feeding position. The driving cam set includes a first driving track and a second driving track to respectively drive the yarn feeding means to proceed the first and second yarn feeding strokes. The second driving track has a driving delay zone to generate a yarn feeding time lag between the first and second yarn feeding strokes. Knitting needles located between the first and second yarn feeding means are guided to a yarn hooking position to respectively hook the yarn due to the yarn feeding time lag.
