Title (EN) APPARATUS FOR MANUFACTURING FLEXIBLE CONTAINERS
(FR) APPAREIL DE FABRICATION DE RECIPIENTS FLEXIBLES
Abstract:
(EN) An apparatus for manufacturing flexible containers of the type comprising particulate material located between two flexible web members (16, 17), the apparatus comprising a first feed means suitably in the form of one or more drive roller assemblies (13, 43) for advancing a first flexible web member through the apparatus, a metering means suitably in the form of a metering roller (12) having recesses (84) on its peripheral face to accomodate the particulate material and to deposit the particulate material onto the first flexible web member, second feed means suitably in the form of a roller assembly (13, 43) to pass a second flexible web member over the first flexible web member containing the particulate material, and sealing means suitably comprising a roller assembly (13) having one of the rollers including heated zones (94) or portions along its external surface such that when the first and second web members pass between the rollers the web members are sealed together along areas corresponding to contact of the web members with the heated zones or portions. In this manner, there can be formed flexible containers or sachets containing particulate material such as super absorbant polymer which can be immersed in water and subsequently frozen to be used as a heat exchange pad.
(FR) L'invention se rapporte à un appareil servant à fabriquer des récipients flexibles du type contenant une substance particulaire plaçée entre deux membranes flexibles (16, 17). L'appareil comprend un premier organe alimentateur conçu sous la forme d'un ou de plusieurs ensembles de cylindres d'entraînement (13, 43) destinés à faire avancer une première membrane flexible à travers l'appareil, un organe doseur conçu sous la forme d'un cylindre doseur (12) dont la face périphérique est conçue ajourée (84) pour recevoir la substance particulaire et la déposer sur la première membrane flexible, un second organe alimentateur conçu sous la forme d'un ensemble de cylindres (13, 43) servant à faire passer une seconde membrane flexible sur la première membrane flexible contenant la substance particulaire, ainsi qu'un organe de fermeture étanche conçu sous la forme d'un ensemble de cylindres (13) dont l'un des cylindres comporte le long de sa surface externe des zones (94) ou des parties chauffées de sorte que, lorsque les première et seconde membranes passent entre les cylindres, elles soient scellées l'une contre l'autre le long des régions correspondant à la ligne de contact des membranes avec les zones ou les parties chauffées. On obtient ainsi des récipients ou des sachets flexibles pouvant contenir une substance particulaire, tel qu'un polymère superabsorbant, et pouvant être immergés dans l'eau et ensuite congelés pour servir de tampon d'échange thermique.
