An apparatus for packing an expandable material in a closed sectional portion of a body, suitable for mass-producing vehicles, such as automobiles efficiently. This apparatus is provided with a manipulator (38) movable to a desired position, an injector (50) fixed to the manipulator, a means (56) for supplying a two-pack urethane foam composition to the injector, and a controller (40) adapted to control the position of the manipulator (10) so that the injector is set in a position in which an expandable material can be supplied to the sectional portion of the body through an injection port of the same closed sectional portion, and control the supply means so that the expandable material can be packed in the sectional portion by only such an amount that was set in accordance with the volume of the interior of the same sectional portion.

Appareil pour emballer efficacement un matériau expansible dans une partie en sections fermée d'un corps, adapté à la production de véhicules en série (par exemple, dans l'industrie automobile). L'appareil est pourvu d'un manipulateur (38) se déplaçant vers une position voulue, d'un injecteur (50) fixé au manipulateur, d'un système (56) alimentant l'injecteur en composition à base de mousse d'uréthane présentée sous deux paquets, et d'un contrôleur (40) commandant la position du manipulateur (10) de sorte que l'injecteur soit dans une position où le matériau expansible peut être injecté dans la partie en sections du corps par un orifice d'injection de la même partie en section fermée, et pour réguler le système d'alimentation de sorte que le matériau expansible puisse être emballé dans la partie considérée, sans excéder la quantité convenant conformément au volume intérieur de la même partie en sections.
