"Improvements in needle tracer devices" for the movement according to the sample of the healds, by palpating a sample cardboard by palpating needles, during the forward and backward movement of the loom, where a heald machine for the The movement of the healds is transmitted impulses through push rods, characterized in that there are several supports that each carry a palpating needle and each a locking bar, and that are each housed in a swinging lever that rotates against the force of a spring radially in relation to the drum that carries the sample cardboard, turning the oscillating levers driven by the continuous operation of the loom in radial direction to the drum that carries the cartons for the drive of the push rod connected to the machine of healds, and that fixed position supports are available for the blocking bars to prevent the movement of rotation of the pal They are oscillating in such a way that the locking bar of the supports, which are seated by the palpating needles on the sample cardboard, are outside the range of reach of the supports, and because the palpator needles do not settle, because a hole in the sample cardboard, the blocking bars are in the area of attack of the supports.
