Title
(EN) THERMOFORMING ASSEMBLY FOR MAKING CONTAINERS
(FR) ENSEMBLE DE THERMOFORMAGE POUR LA FABRICATION DE RÉCIPIENTS
Abstract
(EN)
The thermoforming assembly comprises feeding devices for moving a continuous strip-shaped semi-finished product (21) along a forwarding path (22), along which a forming mould (25) is arranged defining a forming cavity (26) delimited by a base wall (27), a first pair of respectively opposed side walls (28), and a second pair of respectively opposed side walls (29a, 29b). Heating devices (30) operate on the strip-shaped semi-finished product (21) near the forming mould (25), and forming devices (32) are operatively associated with the forming mould (25) and configured to conform the strip-shaped semi-finished product (21) against the base wall (27) and the side walls defining the forming cavity (26). At least one of the side walls (29a, 29b) belonging to the second pair is a movable wall (29a), positionable towards and away from the other side wall (29b) belonging to the second pair, to vary the dimension of the forming cavity (26).
(FR)
L'ensemble de thermoformage comprend des dispositifs d'alimentation pour déplacer un produit semi-fini en forme de bande continue (21) le long d'un trajet d'acheminement (22), le long duquel un moule de formage (25) est disposé définissant une cavité de formage (26) délimitée par une paroi de base (27), une première paire de parois latérales (28) respectivement opposées, et une seconde paire de parois latérales respectivement opposées (29a, 29b). Des dispositifs de chauffage (30) fonctionnent sur le produit semi-fini en forme de bande (21) à proximité du moule de formage (25), et des dispositifs de formage (32) sont associés de manière fonctionnelle au moule de formage (25) et configurés pour conformer le produit semi-fini en forme de bande (21) contre la paroi de base (27) et les parois latérales définissant la cavité de formage (26). Au moins une des parois latérales (29a, 29b) appartenant à la seconde paire est une paroi mobile (29a), positionnable vers et à l'opposé de l'autre paroi latérale (29b) appartenant à la seconde paire, pour faire varier la dimension de la cavité de formation (26).
