Abstract: The invention relates to an apparatus for separating bundled bars, which comprises a magazine for containing the bars in bundles cooperating with means which reduce its width and thus cause the overflow of a certain number of bars from one of its longitudinal sides. The apparatus is also provided with a device for rolling the bars back and forth so to arrange them side by side through a passage where bars are intercepted and withheld by a hooking device which separates the bars singly and release it for transfer to a subsequent operation.
