Abstract
In a plug mill, the plug is contained in a container supported by a carriage which is moved from the plug recovering position to the inlet guide provided in front of the mill along a straight transfer rail positioned at an angle with respect to the pass line of the mill and at a speed sufficient to impart a predetermined moment of inertia to the plug. When the carriage is advanced to a position near the inlet guide, the carriage is rapidly stopped to eject and supply the plug to the front end of the mandrel bar by utilizing the moment of inertia.
