Abstract

290,163. Dougherty, R. S. A., and Greenwell, N. May 7, 1927, [Convention date]. Expanded metal.-Openwork bars and plates are made by transversely slitting or scoring a blank at 6, Fig. 11, as by rollers 8, 7 and rolling or forging or pressing the metal, the section of the bar or of the roll pass being designed so that a variable reduction is effected across the blank section in order to open the slits. An I-beam having had its web 2, Fig. 12, transversely slit or scored may be reduced in one or more passes through a mill comprising horizontal rolls 10, 11 and vertical rolls 12. The cross-section of the web is designed according to the shape of opening required, numerous examples being given in the Specification. An openwork plate 40, Fig. 29, may be made by producing a profiled blank. Fig. 26, slitting or scoring the parts 37 of reduced thickness, and then rolling. The slitting and subsequent reduction may be effected immediately after the rolling of the blank from the ingot.
