Abstract

Afin d'appliquer ponctuellement une colle pompable à chaud sur des parties d'une carrosserie afin d'y fixer des nervures de renforcement, un système chauffé de transport de colle achemine celle-ci depuis une pompe de chauffage jusqu'à un ensemble d'ajutages à points multiples (24, 25, 26, 27), en passant par un doseur central (3) et par des doseurs secondaires (4, 5, 6, 7) montés en aval du doseur principal, de sorte que la colle qui sort par tous les ajutages a la même température indépendamment de la forme et de l'agencement des ajutages individuels (24, 25, 26, 27).
