MANUFACTURING METHOD FOR A LAMINATED SET OF METAL RINGS FOR A PUSHBELT

摘要

The invention relates to a method for manufacturing a laminated set (2) of radially nested metal rings (15) for a pushbelt (1) that comprises at least one such ring set (2) and a multitude of transverse metal elements (3) slideably incorporated on the ring set (2), including the steps of preparing an elongated steel sheet (11), a lengthwise oriented central part (P2-P4) of the steel sheet (11 ) being defined in-between lateral side edges (P1 ; P5) thereof. Wherein the radially innermost ring (15) of the ring set (2) is produced from material located at the central part (P2-P4) of the steel sheet (11).
