Abstract
The apparatus comprises in combination: a computerized opto-electronic reader (3), able to control the fabric pattern moving along a linear transverse inspection zone, said reader being capable of detecting data of pattern deviation from a reference pattern; and a set of actuators (9, 10, 11, 12, 13, . . . N-2, N-1, N) with respective servomotors, with encoder or the like, controlled by the signals emitted by said opto-electronic reader (3). The actuators are disposed to act each on a corresponding fabric zone, to locally correct the pattern deviations detected by the opto-electronic reader.
