ABSTRACT:
The present invention relates to a means for manufacturing section multi-ply cardboard of narrow, less than 30 cm wide, thermoplastic-coated cardboard webs. The means comprises a heating means for heating cardboard webs which are conducted into the means with the aid of guides, substantially one above the other and mutually spaced, nozzles being disposed in the interstices of the webs to direct flames against the surfaces of the webs; a profilator with rolling members, into which the cardboard webs, heated of their surfaces, are conducted for pressing them together between the rolling members and for rolling to desired section or profile shape; and a cooling means for cooling the section or profile. Further the means may comprise a cooling means disposed in the direction of travel of the cardboard profile after the profilator for cooling the cardboard profile formed in the profilator, and a roll assembly disposed after the cooling means, the shape of its rolls substantially consistent with the shape of the cardboard profile profiled in the profilator for conducting said cardboard profile after the cooling means through the roll assembly.
