PROCESS FOR THE PRODUCTION OF BOTTLE-TYPE CONTAINERS OR THE LIKE, WITH THERMOCONFORMABLE SYNTHETIC MATERIAL FILM, AND ASSEMBLY FOR THE MANUFACTURE THEREOF.

摘要

The present invention refers to a process for the production of bottle-type containers or the like, with thermoconformable synthetic material film, and to an assembly for the manufacture thereof, said process comprising a thermoconformable synthetic material film two-band welding phase, the bands being opposite to each other, to define opened alveoli between both film bands in correspondence with a longitudinal edge of the film bands, and a thermoconforming phase wherein a portion of both film bands having said defined alveoli, is inserted into a conforming mold provided with conforming cavities which are positioned in correspondence to the alveoli, and is inserted through the alveoli opened portion, a pressure-fluid in such alveoli interior, to obtain their conformation, by swollen plastic, in the interior of the conforming cavity; both film bands that define the alveoli welding is in a corresponding relationship with the dimensions of said conforming cavities, in such a way so that the welding line defining the alveoli, remains positioned inside the corresponding conforming cavity at a preset distance of the walls of said conforming cavity upon insertion of said film bands in the conforming mold; after thermoconforming phase, a cutting phase is provided for at least the film band portions projecting from both the base portion, and the lateral surface of the containers thermoconformed in correspondence to the alveoli.
