Abstract
799,477. Rolling. MANNESMANN - MEER AKT.-GES. Jan. 23, 1957 [Feb. 8, 1956], No. 2509/57. Class 83 (4). In a cold rolling mill for tubes in which the work 4, Fig. 1, is fed step-by-step along a stationary mandrel 5 and engaged by rolls in a reciprocating carriage 1, the end of the mandrel is supported by a bearing 8 which can be opened to allow the endwise insertion of new workpieces 11. During insertion a chuck 7 holds the mandrel in position while the step-by-step feeding saddle 6 is returned to its starting position near the bearing 8. A pusher 13 then feeds the workpiece 11 from a roller table 12 to feed rolls 9, 10 which force it over the mandrel 5.
