Abstract
An apparatus for producing containers with a film made of thermoplastic synthetic material, having elements for advancing, along an advancement direction, two facing strips of film made of thermoplastic synthetic material; a thermal bonding station including thermal-bonding half-molds which face said two strips of film on opposite sides thereof along the advancement direction of the two strips of film, the thermal-bonding half-molds being adapted to thermally bond the strips of film to each other at preset regions thereof so as to form thermal bond regions delimiting between the two strips of film, a plurality of pouches that are each open at a longitudinal edge end of the two strips of film; a cooling station arranged downstream of the thermal bonding station along the advancement direction and including cooling half-molds being shaped so as to carry out a film strip cooling which is limited only to the thermal bond regions; a thermoforming station, arranged downstream of the cooling station and including a forming mold enclosing molding cavities that are adapted to accommodate each a pouch with portions of the thermal bond regions delimiting the respective pouch arranged inside the molding cavity, which cavity is further provided with an opening located at the open end of the enclosed pouch; and pressurized-fluid injectors for injecting pressurized fluid through the openings of the molding cavities into the pouches.
