DEVICE AND METHOD FOR FILLING A BAG WITH A FLUID MATERIAL AND BAG SUITED FOR THIS PURPOSE

摘要

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.
