Sealing device and rubber hose continuous vulcanizing device provided with same, and sealing method and rubber hose continuous vulcanizing method provided with same

摘要

Damage of the outer surface of a rubber hose due to friction can be prevented while the sealing performance and the productivity are ensured.;The following components are provided: a pipe 11 whose one end is connected to a vulcanization pipe and in which pressed liquid is pumped from an inlet 11a disposed at the side face of the other end side; an annular member 12 which is attached to the pipe 11 so as to close an opening of the other end side of the pipe 11, and includes a hole 12a whose diameter is larger than the outer diameter of a rubber hose and in which the rubber hose passes through; and a pump which pumps more liquid than the liquid discharged outside the pipe 11 through the gap between the hole 12a and the rubber hose into an inlet 11a.
