Knitting machine to produce figured fabrics

An improved knitting machine for the production of figured fabrics, that is, having different colors and patterns, of the kind associated with a crochet-machine and a jacquard device on a sole bearing frame and comprising:

• active members such as a needle-bar movable in an axial direction to the needles, a warp yarn guide bar disposed adjacent the needles and suitable to oscillate in a direction parallel to the lying plane of the needles and to rotate perpendicularly to the same plane, an under-yarn guide bar suitable to oscillate in a direction parallel to the needle plane and perpendicularly to the same, a projection carrier bar movable at right angles to the needle plane, rods suitable to support tubular weft yarn guides disposed side by side on plates parallel to said needle bar and transversely to the needle plane, said plates being movable along their own plane and parallelly to said needle bar in order to define the working oscillations of said rods;
• selection and control members for said active members designed to cause the same active members to intervene according to a predetermined program;
• feeding devices for the yarns forming the fabric;
• and
• conveying means for the produced fabric;
• characterized in that
• said rods are rotatably supported by pivot pins extending at right angles to said plates, as well as stop members for oscillations of said rods, adapted to allow the rods to oscillate symmetrically with respect to vertical planes and to cause the maximal linear amplitudes of said tubular weft yarn guides which correspond to the double distance of two needles in succession, and in that
• said selection and control members include a plurality of kinematic chains suitable to position each of said rods angularly and independently of the adjacent rods.
