Abstract
A circular knitting machine for manufacturing knitted fabrics having patterning effects with a device for increasing the size of the pattern obtainable on the fabric, comrising a needle cylinder provided with needles and needle pushers and at least one pattern drum disposed peripherally with respect to the needle cylinder and provided with a plurality of variously disposed teeth for operating the selection of the needle pushers and needles according to the pattern to be reproduced. The drum is disposed to roll on the needle cylinder and has the teeth disposed at a pitch equal to that of the needles of the needle cylinder. The machine also comprises means for driving the pattern drum which give it a rotational speed about its own axis and a revolving speed about the needle cylinder such that two facing generatrixes of the cylinder and drum become mutually phase displaced after each complete revolution of the drum about the cylinder. Means are also provided for returning the drum to the condition in which said generatrixes are facing each other after a determined number of revolutions of the pattern drum about the needle cylinder.
