The invention concerns a device for continuously filling with a hardening material a bag (2) elongated in shape and with a flattened transversal cross section, this bag having further on its upper surface two longitudinal separable edges initially overlapping. The device comprises means for injecting (21) into the bag a hardening material and a shuttle (26) for moving along the bag, this shuttle being shaped in front for continuously moving apart said longitudinal edges from each other at least in a direction perpendicular to the plane of the bag and for defining a lateral opening extending along a set length to enable the insertion of the injecting means into the bag, the shuttle being further shaped at the rear for continuously bringing together said longitudinal edges so as to make them overlap and assemble them.

L'invention est relative à un dispositif pour le remplissage en continu par un matériau durcissable d'un sac (2) de forme allongée et présentant en section transversale une forme aplatie, ce sac présentant en outre sur sa face supérieure deux bordures longitudinales séparables et se recouvrant initialement, le dispositif comportant un organe d'injection (21) permettant d'injecter dans le sac un matériau durcissable et une navette (26) destinée à être déplacée le long du sac, cette navette étant conformée à l'avant pour écarter en continu lesdites bordures longitudinales l'une de l'autre au moins dans une direction perpendiculaire au plan du sac et définir une ouverture latérale s'étendant sur une longueur donnée pour permettre l'introduction de l'organe d'injection dans le sac, la navette étant en outre conformée à l'arrière pour rapprocher en continu lesdites bordures longitudinales afin de les faire se recouvrir et réaliser leur assemblage.
