Machine for the production of finished knitted articles, of the type of tights or panty-hose

A knitting machine, comprising:

• two fixed bars of needles for production of tubular articles with rows formed partly by needles of one bar and partly by needles of another bar;
• thread displacement means for displacing alternately thread in both directions along said two fixed bars;
• cam rings rotating in continuous motion in opposite directions, each cam ring acting on one of said two fixed bars of needles to provide trajectories of needles of said one of said two bars forming a limited angle, generally less than 30.degree., relative to trajectories of substantially corresponding needles of said another bar, needles of said two fixed bars being arranged offset and controlled by said cam rings in a manner such that hooks of said needles of one of said two bars do not cross over hooks of said corresponding needles and acting on said needles of said two fixed bars simultaneously, said cam rings including cam means for acting on selected needles to carry out a sliding movement greater than a sliding movement for formation of the stitches, to force selected needles to cross one another such that selected needles of both said two fixed bars engage the same thread upon crossing one another during the sliding movement greater than the sliding movement necessary for the formation of stitches.
