The machine possesses two fixed bars of needles, with threads displaced alternately in both directions along the bars together with cam rings rotating in continuous motion and in opposite directions, the tubular articles coming from the machine being closed at one end by a thread engaged simultaneously by the needles of the two bars, and in said machine: the trajectories of the needles (11) of one bar (1) of the two bars (1, 3) form a limited angle relative to the trajectories of substantially corresponding needles (13) of the other bar (3); the needles of the two bars - which are arranged offset - are controlled, for the purposes of the sliding movements necessary for the formation of the stitches of the tubular fabrics, in a manner such that the hooks thereof do not cross over, and such as to be able to work on both bars simultaneously; and - in order to join the fabrics of the two bars - the needles of the two bars are controlled in order to reach positions (111C; 131C) higher than those necessary for the formation of the stitches, in a manner such as to cross one another and engage the same thread simultaneously with the needles of both bars. |
