<p>Apparatus (10) and method to feed and shear metal bars, comprising a shearing unit (16) that shears the metal bars (11) sequentially into segments (12) of desired length, and an alignment and translation unit (15), which feeds the metal bars (11) to the shearing unit (16), provided with butting member (17) suitable to cooperate with the tail ends (Ha) of the metal bars (11) in order to align them longitudinally with respect to each other. The butting member (17) comprises a magnetic portion (19) facing toward the tail ends (1 Ia) of the metal bars (11), and conformed so as to generate a magnetic or electromagnetic attraction force on the tail ends (11a), so as to attract the metal bars (11) to itself and to keep the relative tail ends (11a) substantially aligned and in contact with the butting member (17).</p> |
