摘要
A seal adapted for environments in which high temperatures are experienced and low pressure drops are met is made by coiling in plural spirals about itself a metallic work-hardened tape which has, in cross-section a shape in the form of an open V, a throat-like recess having a semicircumferential outline being formed in correspondence with the apex of the V. The terminal portions of the spirals are held together by rivets or by spot-welding. A machine is also provided to shape the seal, which comprises specially shaped roller pairs arranged in sequential order, so as to effect on the metal tape all the operations which are necessary to impart the expected final shape thereto.
