发明名称 CUSHION MEMBER, METHOD AND APPARATUS FOR MANUFACTURING THE SAME
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).
