发明名称 Sealing device for a pipe joint.
摘要 <p>A sealing device is used to form a lining on the inner surfaces of the joint portions of two adjacent pipes. The sealing device includes an elastic sleeve (22) having end sections (23, 23) and an intermediate section (24) between the end sections. A ring-like, elastic foamed band (30) is wrapped around the outer peripheral surface of the end sections of the sleeve. When the foamed band (30) is pressed by an expanding ring (26) against the inner surface of the pipes, an exudable binder is squeezed out of the foamed band (30) to permit the end sections of the sleeve to be bonded to the inner surface of the pipes. The intermediate section (24) of the sleeve (22) is thinner in its wall than the wall of the end sections of the sleeve to permit an axial expansion of the sleeve.</p>
