ABSTRACT:
The apparatus includes advancement clamps which move two mutually facing films along an advancement direction on which the following are arranged in sequence: two welding half-molds, which by mutually welding the two films in preset regions define cells which are open toward a longitudinal edge of the films; two half-molds for heating the welded films; a cell forming station. Air injection nozzles, inserted between the two flaps of the films on the side of the above mentioned longitudinal edge, and two forming half-molds, in which forming cavities are defined at the cells, operate in the forming station. Divaricators for divaricating the two flaps of the films are provided proximate to the forming station so as to facilitate the insertion of the air injection nozzles.
