Abstract

1,194,136. Making expanded metal; shearing. METALEX CORP. 12 Sept., 1968 [19 Oct., 1967], No. 43347/68. Headings B3A and B3W. In a method of making expanded metal having a roughened surface, sheet metal 28 is fed horizontally to an expanding ledge where it is expanded or both slit and expanded by a vertically reciprocated die which also presses the work against a vertical serrated face of a die 42 to roughen the surface. The roughened surface comprises serrations 17. The metal sheet may be pre-slit or may be sheared by the upper die member 20 which has a plane vertical face co-operating with the peaks of the ribs of the lower die member 42. The upper die member is preferably operated hydraulically and a feed mechanism comprising opposed intermittently operated rollers is operated by means of a crank 38 and eccentric 40 in sequence with the operation of the upper die member.
