Disclosed examples relate to loading devices for loading bars for machining in machine tools. A disclosed example loading device is adapted to move a bar from a starting position to an end position and to feed the bar from the end position to the machine tool, comprising a rest portion for supplying the loading device with at least one bar lying on the rest portion in the starting position, and a movable transport for transporting the bar from the starting position to the end position. The transport is adapted to transport the bar downward in a downward movement due to its gravity along a downwardly inclined guiding portion, the bar being supported by a first support portion of the transport.
