Title (EN) PROCESS AND MACHINE FOR PACKAGING PRODUCTS WITH STRETCHABLE THERMOPLASTIC FILM
(FR) PROCEDE ET MACHINE POUR CONDITIONNER DES PRODUITS A L'AIDE D'UN FILM THERMOPLASTIQUE ETIRABLE
Abstract: front page image
(EN)Means are provided to ensure that during the stage of formation through the tube- forming and longitudinal welding means (1, 18) the wrapping is subjected to longitudinal stretching which causes it to adhere intimately in a direction transverse to the product and this condition is ensured by means which bring about a particular difference in velocity between the jaw (19, 119) which supports the tubular wrapping and causes it to advance and the means (15, 115, 17) which feed the film to the tube-forming means (1) which also remain suitably active during the subsequent stage in which the tubular wrapping is seized posteriorly by the appropriate posterior closing jaw (119, 19), all in such a way that the wrapping film runs over the said tube- forming means in an almost continuous movement to prevent localised appearance defects in the packaging and to assist operation of the longitudinal welding means (18) which are then able to operate substantially continuously.
(FR)L'invention concerne un moyen pour assurer que, lors de l'étape de formation faisant appel à un moyen (1, 18) de formation de tube et de soudure longitudinale, le film d'enveloppement est soumis à un étirement longitudinal provoquant l'adhésion intime de ce film au produit, dans une direction transversale. Ceci est garanti par le moyen qui amène une différence particulière de vitesse entre les mâchoires (19, 119) qui supportent le film d'enveloppement tubulaire et qui le font avancer, et le moyen (15, 115, 17) qui fournit le film au moyen de formation de tube (1), qui reste également actif de manière appropriée, lors de l'étape suivante, dans laquelle le film d'enveloppement tubulaire est saisi postérieurement par la mâchoire de fermeture postérieure correspondante (119, 19), de sorte que le film d'enveloppement passe sur le moyen de formation de tube, dans un déplacement presque continu, pour éviter des défauts d'aspect localisés dans le conditionnement, et pour aider au fonctionnement du moyen de soudure longitudinale (18) qui peut ensuite fonctionner sensiblement continuellement.
