Method of manufacturing seals

摘要

A method of manufacturing a leaf seal for use between rotating components comprises forming corrugations within a metallic strip and feeding the corrugated strip into a seal guide. The corrugated strip is then pressed into the guide by an angled ram such that the corrugations lie at an acute angle to the perpendicular axis. The strip is then secured in a seal carrier, the free ends of the corrugations thus forming the angled sealing leaves of a leaf seal.
