Improvements introduced in the traction means of heald frames in which it is characterized as an essential basis to practice the movement of traction of the chains that raise the frame of the comb in vertical direction which is executed by linking the ends of the two chains in an almost coincident point determined by a forked part that connects to the end of a lever arm that has its seat or point of support in a place of an upright that is integral with the general bed of the machine and receives its angular oscillation movement through the alternate rhythm that the articulated rods print on an eccentric that receives its reciprocating movement by means of a worm that feeds its turning force by suitable gear with the general motive axis of the machine.
