Process for production of knitted articles

A process for production of knitted articles comprising at least steps of:

• predisposing a linear knitting machine for warp knitting, of a double-bed raschel type, comprising:
• a bearing structure,
• knitting elements mounted on the bearing structure and comprising a first needle bed having a first plurality of needles aligned with one another, and a second needle bed having a second plurality of needles aligned with one another;
• a first jacquard bar provided with a plurality of odd jacquard-type thread-guides configured for selectively supplying threads to the needles of the needle beds;
• a second jacquard bar provided with a plurality of even jacquard-type thread-guides configured for selectively supplying threads to the needles of the needle beds;
• a third jacquard bar provided with a plurality of odd jacquard-type thread-guides configured for selectively supplying threads to the needles of the needle beds;
• a fourth jacquard bar provided with a plurality of even jacquard-type thread-guides configured for selectively supplying threads to the needles of the needle beds;
• wherein each of the odd and even jacquard-type thread-guides is individually and selectively mobile, by means of a corresponding jacquard-activation element, between a base position and an activation position, displaced by a needle space with respect to the base position, and wherein each of the jacquard bars is configured to carry out a respective linear shog movement, frontally and posteriorly to tips of the needles of the needle beds, and a respective oscillating swing movement, substantially perpendicular to and substantially alternated with the respective shog movement and carried out by sides of the needles of the needle beds so as to bring the threads alternatively in front of and behind the tips of the needles, the shog movement and the swing movement enabling production of at least a knitted article on the needle beds;
• and
• producing at least a portion of the knitted article by means of a base movement of the jacquard bars, wherein:
• the first jacquard bar, the second jacquard bar, the third jacquard bar and the fourth jacquard bar are moved, in each knitting row, so as to operate alternatively at the first needle bed and the second needle bed;
• the first jacquard bar and the third jacquard bar are moved simultaneously with a shog movement identical to one another on a same bed of the needle beds;
• and
• the second jacquard bar and the fourth jacquard bar are moved simultaneously with a respective shog movement identical to one another on a same bed of the needle beds.
