Abstract

403,684. Sawing; sand-blast. REPUBLIC STEEL CORPORATION, Republic Building, Youngstown, Ohio, U.S.A.-(Assignees of Neckerman, W. M.; Republic Building, Youngstown, Ohio, U.S.A.) March 24, 1932, No. 8864. Convention date, July 9, 1931. [Classes 60 and 145 (ii).] In a process for making tubes from metal strip a machine D blows cast-iron balls against the margins of the strip to effect cleaning prior to welding. A conveyer then passes the tube to a saw-table K comprising a conveyer 1 which feeds the tube to a right-hand position where the end is trimmed by a reciprocated rotary saw S. A conveyer 2 then transfers the tube to a left-hand position where the other end is trimmed by a saw S'. Specifications 399,153, 399,474, 399,532, [all in Group XXII], 403,963, and 403,965, [Group XXII], are referred to.
