Title
(EN) SYSTEM AND METHOD FOR MANUFACTURING AN ELECTRIC HEATER
(FR) SYSTEME ET PROCEDE DE FABRICATION D'UN DISPOSITIF DE CHAUFFAGE ELECTRIQUE
Abstract
(EN)
The invention relates to a method and a system of manufacturing an electric heater (1) intended for heating foam-moulded cushions for e.g. vehicle seats or mattresses, said heater (1) comprising an electric conductor (2) which preferably consists of an insulated or non-insulated metal wire. The method comprises the steps of arranging a plurality of protruding members (10) forming part of a conductor layout structure (9) in a pattern adapted to the configuration of the heater (1), arranging a conveyor (13) which is equipped with a follower (14) along a track (13) which essentially corresponds to the desired configuration of the heater (1) around said protruding member (10), and moving said conveyor (13) while said follower (14) deposits said conductor (2) along said track.
(FR)
L'invention se rapporte à un procédé et à un système de fabrication d'un dispositif de chauffage électrique (1) conçu pour le chauffage de coussins moulés dans une matière alvéolaire, du type sièges de véhicule ou matelas, ledit dispositif de chauffage comportant un conducteur électrique (2) constitué, de préférence, d'un fil métallique isolé ou non isolé. Ledit procédé consiste à agencer une pluralité d'éléments protubérants (10) faisant partie d'une structure de mise en place du conducteur (9) suivant un motif adapté à la configuration du dispositif chauffant (1), à disposer un dispositif transporteur (13) équipé d'un suiveur (14) le long d'un tracé (13) qui correspond sensiblement à la configuration souahitée du dispositif chauffant (1) autour dudit élément protubérant (10), et à mettre en mouvement ledit dispositif transporteur (13) tandis que ledit suiveur (14) dépose ledit conducteur (2) le long de ladite piste.
