Abstract

5378. Roberts, E. S. March 4. Rolling.-Rolls for rolling taper sheets, strips, and hoops of metal are made slightly conical for rolling sheets tapering in thickness tranversely, or have deepening depressions for rolling strips &c. tapering in the direction of their length. In the form of rolls shown in Fig. 1, the upper roll is slightly conical, with a bearing-collar a', the lower roll being cylindrical ; but the rolls may be interchanged, or each may have a conical portion with a bearing-collar. In the form shown in Fig. 3<A>, the upper roll has a deepening depression a<3>, the lower roll being plain. One or more such depressions may be formed in the top roll, or it may be of a spiral shape with a shoulder a<4>, Fig. 7. The sheets may be rolled thicker at the edges than the middle by using a barrel-shaped top roll, and the depressions may be so shaped as to roll strips tapering from the middle to each end. The taper sheets or strips may be used in the manufacture of cycle forks, tubes, tubular handles, &c.
