ABSTRACT:
In an apparatus for automatically feeding bar stock material into a numerically-controlled automatic lathe, a bar is rotatably clamped and borne by the clamp jaws of several bearing clamps disposed in a row at intervals along the bar and orientated at respectively different angles about the bar, each clamp jaw comprising three pulleys in triangular formation and an endless belt supported on these pulleys, one of which is driven, the bar being clamped between a span of the belt between two pulleys of one jaw and that of the other jaw of each bearing clamp. The bar is thus held at clamping positions that vary helically about the bar as it is fed by a feed pipe into the lathe.
