Abstract
PURPOSE: To coat the inner surface of piping, e.g. gas, water supply pipes, etc. with certainty, by inserting and bonding a thin cylindrical film to the surface of the continuous ring-shaped adhesive layer formed on the inner surface of the piping.
CONSTITUTION: A liquid adhesive is injected into the interior of the piping 1 while being foamed by a blower, and the adhesive layer S is formed by discharging the adhesive with compressed air, etc. The cylindrical film 6, e.g. polyethylene, etc. with its tip in close contact with the film outlet 7t is bonded to the surface of the adhesive layer while being reversed by pressure of air sent to the drum 7
