Abstract

Positioning and protection device (10) for a bending machine (11), provided at least with a work plane (13) on which one or more metal bars (12) to be shaped are disposed and made to advance. The device (10) comprises at least a covering element (15, 16) having at least a first, operating position in which it extends longitudinally for a substantial part above the work plane (13) of the bending machine (11) and defines at least with the work plane (13) a sliding channel for the metal bars (12). The covering element (15, 16) is associated with movement means (22) able to move it selectively between the first, operating position and a second, discharge position, in which it lowers completely below, or at most flush with, the work plane (13), leaving it completely free.
