Title (EN) APPARATUS AND PROCESS FOR SEALING THERMOPLASTIC MATERIALS
(FR) APPAREIL ET PROCEDE DE THERMOSCELLAGE DE MATIERES THERMOPLASTIQUES
Abstract:
(EN) An apparatus (10) for heat sealing a thermoplastic material (36) to a substrate (38) has mounting means (12) for mounting the thermoplastic material and the substrate in mutual contact at an area to be heat sealed. Heat sealing is achieved using sealing means, having a first end and a second end, to seal the area to be heat sealed and pressure control means is associated with the sealing means for establishing a pressure gradient between the first and second ends where more pressure is applied at one end and less pressure is applied at the other end. As well, a temperature control means is provided for establishing a thermal gradient between the first and second ends, where the thermal gradient provides at least one location encompassing the melting temperature or melting temperature range for at least one of the thermoplastic material and the substrate, between the first and second ends.
(FR) L'invention concerne un appareil (10) de thermoscellage d'une matière plastique (36) à un substrat (38), possédant un moyen formant socle (12) permettant de mettre la matière thermoplastique et le substrat en contact mutuel dans une zone à thermosceller. Le thermoscellage est obtenu à l'aide d'un moyen de scellage, possédant des première et seconde extrémités, pour sceller la zone à thermosceller et un moyen de commande est associé au moyen de scellage afin qu'un gradient de pression soit établi entre les première et seconde extrémités, une pression plus importante étant appliquée sur une extrémité. Le moyen de commande de température est conçu pour établir un gradient thermique entre les première et seconde extrémités, gradient permettant à au moins un endroit d'atteindre la température de fusion ou de se trouver dans la plage de températures de fusion pour la matière thermoplastique et/ou le substrat, entre les première et seconde extrémités.
