Zusammenfassung:	PURPOSE:To obtain strong connection forces without lowering of joint pressure by a method in which an unvulcanized rubber thin plate is interposed between end faces of rubber packings and the rubber packings are vulcanized and connected through the rubber thin plate by pressing them by a pressure applied to the rubber packings. CONSTITUTION:A rubber paste is applied to the end face of water-stop rubber packings 1, and the packings 1 are set in molds 8. An unvulcanized rubber thin plate 5 is put between the end faces of the packings 1 and pressed by pressures applied to the packings 1, where vulcanized rubber pipes 6 thrust through the cavities 7 of the plate 5 are fitted into the cavities 2 of the packings 1. Strong pressures can thus be applied to the joints without causing the inflow of unvulcanized rubber into the cavities.
