A supplement to Ures Dictionary of Arts, Manufactures, and Mines, : containing a clear exposition of their principles and practice. . so thewheel by means of which the revolution is communicated. The cheeks are of cast iron,very massive, that they may bear the violent usage to which they are subjected. We cannot go into the numerous purposes to which rolling mills of this kind are applied;a few miy be mentioned. The practice of .-flitting sheets of metal into light rods, cither for the use of the wire-drawers or of nail-makers, is carried out by means of two large steel rollers, channelled 958 ruthenium:. circularly, as in Jt^. 598. These are so placed that the cutters or raised parts of one roller,which are exactly turned for that purpose, shall work in corresponding channels of the otluiroller, thus forming what may be called revolving shears, for the principle is that of clii)-ping; so that a sheet of metal on being passed through this machinery, is separated into slipisagreeing in size with the divisions of the rollers. Rolling mills have been patented for rolling tubes for gas and other purposes. See Tubes. 599.
