摘要： A cushion manufacturing apparatus comprises a plurality of nozzles for continuously discharging a softened thermoplastic resin, thereby looping a plurality of continuous filaments with the respective contact portions thereof bonded together, first guide portions (41, 42) for moving the continuous filaments inward from opposite surfaces in the thickness direction of the cushion member as the filaments are looped, and second guide portions (43, 44) for moving the filaments inward from the opposite sides of the cushion member. The guide portions (41, 42; 43, 44) are provided with a plurality of rollers (50, 52, 60, 62) individually having outer peripheral surfaces projected or recessed corresponding to the outline of the profile of the cushion member and belts (54, 55, 64, 65) stretched between the rollers and capable of endlessly running to change the respective shapes thereof depending on the respective shapes of the outer peripheral surfaces of the rollers, thereby forming the shaping guide surfaces (56, 57, 66, 67).

摘要： In manufacturing molded product of urethane foam, a releasing agent mainly composed of organopolysiloxane is applied on the inner surface of the mold maintained at 60 DEG C. The agent is prepared by dissolving the base composed of organopolysiloxane composition in an organic solvent. The organopolysiloxane composition comprises (a) a first organopolysiloxane of which 0.1 to 5.0% of all organic groups bonded with Si atoms are vinyl groups, and at least 80% of the remaining organic groups are methyl groups, and (b) a second organopolysiloxane containing at least three Si bonded hydrogen atoms in one molecule, wherein the first and second organopolysiloxanes contain Si vinyl groups and SiH groups at a ratio in a range of 1 : 0.5 to 1 : 5, and do not substantially contain unreactive siloxane. The agent is cured by irradiation with ultraviolet rays. Inside the mold is injected a raw liquid of urethane foam of cold cure-type.

摘要： In the manufacture of seat pads by the foaming of urethanes, moulds in which the foaming is performed, consist of a mould top (4) and a mould bottom (3). Indented portions corresponding to a seat shape are formed in the mould top (4). Slits (6) into which partitions (5) to divide the mould are inserted, are provided in the mould top (4). Foamed original solutions (10) and (12) for a low hardness foamed material and a high hardness one are respectively poured into an intermediate portion and both side portions of the mould bottom (3) respectively. After dividing the mould at the intermediate portion and the portions on its left and right sides by application of the mould top (4) to the mould bottom (3) and insertion of partitions (5) through slits (6) on left and right sides, both foamed original solutions (10) and (12) are allowed to foam simultaneously. Then the partitions (5) are drawn out. As a result urethane foams having different hardness are integrally formed in the mould, and an integrated moulded product is obtained.
