Definitions
- the drawing unit according to the present invention is applied, preferably but not restrictively, to machines that simultaneously work at least two bars, round pieces or metal wires at a time, carrying out a substantially uniform, coordinated and simultaneous feed.
- a pair of contrast rollers facing each other and not constrained to each other, can be positioned opposite one motorized roller, where each of them exerts a certain pressure on a metal product in the direction of the motorized roller.
- - figs. 2, 3 and 4 are lateral views of the drawing unit of fig. 1, in different conditions of use.
- one or more motorized rollers 12, 13 there can be opposed at least one pair 19, 20 of contrast rollers 15, 16 and 17, 18 substantially facing each other, unconstrained from each other and independent of each other.
- each motorized roller 12, 13 there can be opposed, with respect to the axis of feed X, a respective pair 19, 20 of contrast rollers 15, 16 and 17, 18.
- Each pair 19, 20 of contrast rollers 15, 16 and 17, 18 comprises two contrast rollers 15, 16 and 17, 18 substantially facing each other, substantially coaxial, unconstrained from each other and independent of each other.
- two contrast rollers 15, 16 and 17, 18 of the same pair 19, 20 are disposed in succession in a direction substantially parallel to their axes of rotation Fl, F2 and F3, F4.
