Abstract
Apparatus for making a pack tray includes a body with a strip of side walls, the body including an outer envelope lined on the inside with an added sealed plastic film. The apparatus includes at least one station provided with elements for applying glue on a portion at least of the inner surface of the side wall strip of the outer envelope, also called gluing area, before placing a plastic film. The gluing pads include at least one block of a porous material that can, one the one hand, be filled with glue by loading members through a diffusion phenomenon, and that can deposit glue by contact optionally combined with a compression force on the gluing area. The pad is mounted on a bearing structure via members for handling it between expanded positions in which the pad contacts the gluing area for applying glue thereon and a folded position in which the gluing pad is remote from the outer envelope of the pack tray.
