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).
Cette invention concerne un dispositif de fabrication comprenant une pluralité d'injecteurs qui déchargent en permanence une résine thermoplastique tendre sous forme d'une pluralité de filaments qui s'enroulent et dont les parties en contact sont collées les unes aux autres. Des premières parties de guidage (41, 42) font avancer les filaments continus à partir de surfaces opposées dans le sens de l'épaisseur de l'élément de coussin, et des secondes parties de guidage (43, 44) font avancer les filaments à l'intérieur à partir des côtés opposés de l'élément de coussin. Les parties de guidage (41, 42; 43, 44) sont munies d'une pluralité de galets (50, 52, 60, 62) présentant chacun des surfaces périphériques extérieures en saillie ou en creux correspondant à la forme extérieure de l'élément de coussin. Des courroies (54, 55, 64, 65) tendues entre les galets et tournant en continu permettent de modifier les formes respectives en fonction de la forme des surfaces périphériques extérieures des galets, ce qui forme les surfaces-guides de formage (56, 57, 66, 67).
