Abstract
PURPOSE:To inject lubricant through a slit and make the supplying of the lubricant to a crude pipe easy by abutting a plug against the slit at the end of a plug bar provided therein with a lubricant feed pipe. CONSTITUTION:When a crude pipe 1 is extruded in the direction of an arrow C, the crude pipe 1 picks up a plug 3 and further the crude pipe 1 advances. Thence, the plug 3 abut's against the end fitting 6 of a plug bar 5. At the same time, the crude pipe 1 is bitten into rolls 17 and rolling is begun. A fixed amount of a lubricant is then mixed with compressed air and the mixture is supplied by way of the discharge port 7 of a lubricant feed pipe 10 and a slit 8 during rolling of the crude pipe 1. Next, the crude pipe 1 retreats and in the rolling of the 2nd pass, the lubricant is supplied into the crude pipe 1.
