Abstract: The bar feeder comprises an oscillatable magazine in which bars are arran so as to form a substantially vertical plane. A bar pusher is arranged at the top of the magazine; in one angular position of the magazine, the bar pusher pushes the upper bar into the mandrel of the lathe. Another pusher is arranged to the side of the bar pusher and, in the other angular position of the magazine, it pushes the bars towards the machining tools of the lathe. The magazine comprises two walls defined by a series of rods and uprights which can be spaced according to the diameter of the bars.
