CA 2112738

A horizontal form fill packaging and sealing apparatus comprises a film dispenser and a film forming plow which, together with a roller guide, forms the film to be sealed into a tube with the free edges at the side. The object to be packaged is inserted into the film tube. The free edges of the film are longitudinally sealed together at the side of the package by a rotary heat sealer and immediately cooled to approximate impulse sealing, and a cross seal is made at the front and back of the object to be packaged. The excess gas in the package is pressed out by a presser before the back cross seal is made.

Formeuse-remplisseuse-scelleuse horizontale comportant un distributeur de pellicule et un dispositif qui sert à former la pellicule et qui, en association avec un rouleau-guide, forme la pellicule devant être scellée en tubes à extrémités libres. L'objet à emballer est inséré dans le tube en pellicule. Les extrémités libres de la pellicule sont scellées longitudinalement sur le côté de l'empaquetage au moyen d'une thermoscelleuse rotative et sont ensuite immédiatement refroidies selon un procédé similaire au scellage à impulsion; la pellicule est ensuite scellée transversalement à l'avant et à l'arrière. L'excès d'air se trouvant dans l'emballage est exprimé au moyen d'une presse, avant que la pellicule soit scellée transversalement à l'arrière. .
