Abstract
A knitting machine is provided for producing tubular articles based on two fixed bars of needles wherein rows are formed partly by the needles of one bar and partly by the needles of the other bar. A thread is provided which is displaced alternately in both directions along the bars. Cam rings are provided rotating in continuous motion and in opposite directions. Each of the cam rings including cams acting on one of the needle bars for providing trajectories of the needles of one of the two bars forming a limited angle, generally than 30.degree., relative to the trajectories of the corresponding needles of the other bar. The needles of the two bars are arranged offset and are controlled by the cams to provide the sliding movement necessary for the formation of the stitches of the tubular fabrics. Sliding movement is provided such that the hooks do not cross over during the formation of stitches such that it is possible to work on both bars simultaneously. For joining the fabrics of the two bars, the needles of the two bars are caused to carry out sliding movements greater than the normal stitch formation sliding movement. In this way, the needles do cross one another and engage the same thread, during the crossover.
