SEMI-AUTOMATIC MACHINE FOR FOLDING AND GLUING PAPER COVERING BORDERS FOR CARDBOARD AND OTHER MATERIALS The machine is used to fold and glue paper covering borders onto cardboard or other materials and comprises: a folding element (9) with a symmetrical row of bristles for folding and gluing the borders passing through in both directions and capable of acting alternately in the two opposite directions; and, on both sides of said mechanism, symmetrical receiving, pressing and advancing elements (1, 3, 5, 7; 21, 25, 27), between which the semi-finished article is fed in a first direction of advance (fA) which is orthogonal to one side of the semi-finished article, and which are capable of operating alternately in two opposite directions (fA, fB) to carry out the folding of the two parallel and opposite borders of the article; a single article may be inserted twice in orientations orthogonal to each other for the folding of the four borders.
