Abstract

L'invention concerne un dispositif de soudage à molettes à bandage pneumatique pour machine à empaqueter. Ledit dispositif comporte un bandage pneumatique sur chaque molette de soudage et un dispositif permettant de modifier la pression pneumatique de chaque bandage pour compenser des écarts de dimension et de position et assurer l'application d'une pression de soudage correcte par chaque molette aux bandes à souder par rapport aux autres molettes. Application au soudage de bandes de matière plastique pour former des emballages hermétiques.
