Abstract

814,116. Rolling tubes. EISENWERKGESELLSCHAFT MAXIMILIANSHUTTE A.G. March 19, 1957 [March 23, 1956], No. 8936/57. Class 83 (4). In a method of rolling tubes c, Fig. 3, over a mandrel a on which they have been pierced the tubes are rolled in three housings d of driven rolls which are spaced apart so that the tube is engaged by only one set of rolls at a time. The housings d may have a common drive and are followed by housings e of non-driven rolls through which the work is pushed to run out rollers g by means of feed rolls f which are mechanically or hydraulically pressed into engagement with the rod a. The feed rolls f are arranged between and beyond the housings d and may be automatically engaged as the tube passes.
