摘要

A rotating anvil (40) having a cavity (54) in the shape of a desired upset head (19) is urged against the tail (11) of a composite fastener (10) protruding through a workpiece (15) and the tail (11) is heated and deformed by friction into an upset head (19) sufficiently larger than the fastener shank (13) to prevent the fastener (10) from being withdrawn from the workpiece (15).
