The drawing assembly in machines for working metal profiles comprises at least one couple of counter-rotating drawing wheels (11, 12), between which are tightened the metal profiles (2) to be fed. Said drawing wheels (11, 12) are doubled so that each couple of wheels defines a first wheel (11a, 12a) and a second wheel (11b, 12b), independent from each other, arranged side by side and coaxial to each other. At least one (11a, 12a) of said first and second wheel placed side by side is motor driven and is counter-rotating with an opposite pressure wheel (11b, 12b) freely rotatable or equally motor driven, coplanar to it, to tighten a respective metal profile (2). |
