<p>The invention concerns a method consisting in: continuously extruding, by means of a die with multiple slots, parallel films (31) of thermofusible material inside a cooling chamber (4), producing airtightness between the longitudinal edges of the films and the walls of the chamber; and in generating by turns in this chamber, and from the end located on the side of the die, successively in the different sections located on both sides of each film (31), low pressure and supply of cooling fluid, the two sections located on both sides of the same film being subjected, one to low pressure and the other to the supply of cooling fluid, and inversely during the next phase, so as to produce the deformation of the films and their being soldered two by two thereby producing honeycombs (36).</p> |
