Abstract
An apparatus for automatically inserting a plug in and to a predetermined position therein a raw pipe such as an aluminum pipe which is to be drawn for instance in a drawbench. The apparatus comprises a suppport roller which supports a plug-supporting rod at its intermediate portion near to an end of the rod, the support roller bearing a lower surface of the portion and being movable along the plug-supporting rod. The apparatus further comprises a pipe-transporting device for transporting the raw pipe, which device grips both ends of the raw pipe so as to move it towards the plug-supporting rod in a direction in alignment with an axis of said rod. A pusher protrudes forward from the pipe-transporting device so that the device starts to carry the support roller at a given instant whereby the raw pipe is prevented from directly riding the support roller and is thus protected from being scratched, and forcible pressing of the plug onto an inner surface of the raw pipe being also avoided.
