ANNULAR CASKET FOR STATIC SEALING FOR VERY HIGH TEMPERATURES AND SMALL PRESSURE DROPS, AND METHOD OF MAKING. - ABSTRACT OF THE DISCLOSURE . - 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 it- self 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 out- line 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 spe- cially 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.
