<p>An apparatus (10) for working metal bars comprises a store (16, 116) for storing and feeding the material to be worked, a work unit (34) for working the bars and at least a drawing unit (24) to pick up the material to be worked from the store (16, 116) and to draw it toward the work unit (34) in a determinate direction of feed (X). The store (16, 116) comprises first feed means (17, 117) able to be activated to feed the metal material from a roll (12) and second feed means (19, 119) able to be selectively activated as an alternative to the first feed means (17, 117), in order to feed the pre-sheared metal bars (14) from bundles. The apparatus (10) also comprises a straightening unit (26, 126) of the mobile type, which is selectively positionable between the drawing unit (24) and the work unit (34) in the work line in the direction of feed (X) according to a condition of activation of the first (17, 117) or second (19, 119) feed means.</p> |
