摘要

A method of manufacturing a spherical sealing body for use in exhaust pipe joints, including the steps of; laminating a flexible refractory sheet and a flexible wire net with each other, winding the laminated refractory sheet and the wire net to thereby form a cylindrical member, laminating the other flexible refractory sheet and an unsintered tape or film made of a polytetrafluoroethylene resin to each other, compressing to integrate the laminated other refractory sheet and the unsintered tape or film in a direction of the thickness thereof to thereby form an sliding face member, winding the sliding face member to an outer circumferential surface of the cylindrical member to thereby form a cylindrical preform body, and applying compression to the preform body in an axial direction of the preform body, and a spherical sealing body for use in exhaust pipe joints manufactured by the method above mentioned.
