PURPOSE:To improve dispersion of liquidized substance within foamed stuff and to perform pouring of the same easily, by a method wherein the liquidized substance is poured into a slit from a pouring nozzle while said slit is being expanded after formation of the slit on the foamed stuff. CONSTITUTION:A slit (example, 3mm. in width and a distance of 5-100mm. between slits are desirable) 3 is formed on foamed stuff (example, soft and semihard urethane foam whose hardness at the time of 25% compression is less than 0.1kg/cm<2> and repulsive elasticity is more than 30%) 2, and liquidized substance is poured into the slit through a pouring nozzle 1 by making either of the foamed stuff 2 or the pouring nozzle 1 of the liquidized substance (example, adhesive agent) or both of them run while the slit is being expanded. For instance, pouring is performed while the nozzle 1 or the foamed stuff 2 is being made to run by inserting the tip part 1a in the inside of the slit 3 by making use of the pouring nozzle 1 whose widthward diameter of the tip part 1a is larger than the width of the slit. USE:The titled method is used for formation of the ceiling of a vehicle. |
