<p>A feeding assembly (10) for machines (M) treating multicolor endless wire-like elements (21) is disclosed, comprising a frame (11) supporting a bobbin (12) on which the wire-like element (21) is wound, a driving unit (13) for the bobbin (12) to cause rotation of the wire-like element (21) around its longitudinal axis (X) and a detection unit (14) of the rotation of the wire-like element (21) around its axis (X). The detection unit is arranged downstream of the bobbin (12) and emits as an output (14a) a logic signal. A central unit (15) operatively connected to the detection unit (14) acquires and processes the logic signal and controls the driving unit (13). The detection unit (14) comprises an optical detector (30) with adjustable sensitivity for reading one of the colors. <IMAGE></p> |
