A machine for the manufacture of air-filled pillows comprises a mounting (14, 114) on which a roll (16) of thin-walled plastic tube is mounted, and drive means (50, 150) to draw the flat-wound tube from the supply and to feed the tube intermittently through the machine. The machine comprises injection means (70, 74: 170, 174) operative intermittently to inject air into the space between upper and lower walls (16a, 16b) of the tube, and a sealing means (60, 160) downstream of the injection means, and which is operative intermittently to seal the upper and lower walls of the tube together, particularly around the aperture through which air has been injected, and to provide a tear-line between adjacent pillows. The machine comprises a separator member (20, 120), which may be located manually within the tube upstream of the injection means, means (30, 130) being provided to maintain the separator member in an operative position within the machine during advancement of the tube through the machine. The separator member (20, 120) is operative to retain the upper and lower walls (16a, 16b) of the tube apart, and in particular comprises a rear housing (24, 124a), provided with an injection aperture through which an injection nozzle (76, 176) of the injection means may be inserted, having previously passed through one of the walls of the tube, to inject a quantity of air into the space between the upper and lower walls.

La présente invention concerne une machine destinée à la fabrication de coussins gonflables, qui comprend une monture (14,114) sur laquelle un rouleau (16) de tube plastique à paroi mince est monté, et un moyen d'entraînement (50,150) qui tire le tube enroulé à plat depuis le rouleau d'alimentation et l'introduit dans la machine par intermittence. La machine de l'invention comprend des moyens d'injection (70, 74: 170, 174) qui injectent de l'air par intermittence dans l'espace situé entre la paroi supérieure et la paroi inférieure (16a, 16b) du tube, et un moyen de scellement (60,160) en aval des moyens d'injection, qui scelle entre elles par intermittence la paroi supérieure et la paroi inférieure du tube, en particulier autour de l'ouverture à travers laquelle l'air a été injecté, et qui forme une ligne de déchirure entre les coussins adjacents. La machine comprend un élément de séparation (20,120), qui peut être placé manuellement à l'intérieur du tube en amont des moyens d'injection, des moyens (30,130) permettant de maintenir l'élément de séparation dans une position de fonctionnement à l'intérieur de la machine pendant l'avance du tube à travers la machine. L'élément de séparation (20,120) maintient séparées la paroi supérieure et la paroi inférieure (16a,16b) du tube, et il comprend en particulier un boîtier arrière (24,124a) muni d'une ouverture d'injection à travers laquelle la buse d'injection (76,176) des moyens d'injection peut être insérée, après être d'abord passée à travers l'une des parois du tube, pour injecter une quantité d'air dans l'espace situé entre la paroi supérieure et la paroi inférieure du tube.
