Abstract

L'invention vise à produire un matériau d'emballage à effet amortisseur, fabriqué par remplissage d'un tube cylindrique en résine synthétique dans lequel des orifices d'introduction d'air ont été pratiqués à l'avance. Ce remplissage s'effectue avec de l'air, le tube étant dilaté par des suceurs à vide de façon à former en continu un corps creux. Ce matériau est constitué par un tube en résine synthétique, dans lequel des orifices d'introduction d'air ont été pratiqués à l'avance à des intervalles réguliers. Ce tube est aspiré par deux paires de suceurs à vide, et de l'air est ensuite introduit dans le tube, les suceurs à vide étant déplacés vers l'extérieur à mesure que le tube est aspiré. Les parties du tube ainsi obtenu qui sont placées sur les côtés avant et arrière des orifices d'introduction d'air sont thermiquement fondues par intersection de joints renfermant hermétiquement l'air dans le tube. La partie centrale d'un corps creux, dont les orifices d'introduction d'air ont été fermés hermétiquement par les joints d'intersection, est thermiquement fondue par un joint déplaçable longitudinalement, de façon à séparer en deux le corps creux. Des matériaux d'emballage amortisseurs sont formés en continu à mesure que la pression interne du corps creux est accrue.
