Abstract
The circular knitting machine comprises at least one sinking cam and one movable cam enabling a selection of knitting elements to occupy several positions. The sinking cam is rotatably biased into a working position in which its working ramp cooperates with the butts of the knitting elements selected for knitting and can be moved to a rest position in which the working ramp cooperates with the knitting elements which are welting. The sinking cam is held in its rest position by a surface thereon which engageingly cooperates with a locking means on the movable cam when the movable cam is in a position to cause the knitting elements to welt.
