US 2026/0116033 A1 · METHOD AND MACHINE FOR PRODUCING AN ARTICLE COMPRISING A FOLDED SHEET

Abstract

Method and machine (1) for producing an article (A) comprising a folded sheet (F), the machine (1) comprising two support elements (4) that are movable and directly consecutive to each other, structured to hold the sheet (F) disposed on them; a first deposition system (11) for arranging the sheet (F) on the two support elements (4); a second deposition system (61) for arranging a base layer(S) in correspondence with the two support elements (4); a gluing material dispensing system (81); and a control unit (10) configured for: arranging the sheet (F) on holding onto the two support elements (4), reciprocally approaching the two support elements (4) for making on the sheet (F) a fold (P), bringing two terminally opposite folding lines (P1a, P1c) of the fold (P) into mutual contact, applying gluing material onto the sheet (F), and coupling the base layer(S) to the sheet (F) for producing the article (A).

Dependent claims

A method for producing an article comprising a folded sheet said method comprising the steps of:

i) providing a plurality of support elements mutually movable, two directly consecutive support elements of said plurality of support elements being placed at a non-zero mutual initial distance;
ii) arranging a sheet on holding onto said two support elements;
iii) reciprocally approaching said two support elements for making on said sheet a fold comprising at least three folding lines arranged in spatial sequence on said sheet;
iv) bringing two terminally opposite folding lines of said at least three folding lines into substantial mutual contact;
v) with said two terminally opposite folding lines into substantial mutual contact, applying a gluing material on said sheet at opposite side to said two support elements;
vi) coupling a base layer to said sheet with said gluing material interposed between said base layer and said sheet, for producing said article.
