Abstract (en)
The paper (L) glued to one face of the board (S) has borders (L1, L2...) which project from the edges (B1, B2...) of the board (S) for folding down over these edges; after an initial border (L1) has been folded over to cover the corresponding edge (B1) of the board, in the portions (LX) projecting from the corners (A) of the said edge, two tools (148) positioned level with the thickness of the board (S) are used to act on the said portions and thereby create an inward tuck and a fold, in order to prepare the manufacture for the folding down of the adjacent border (L2) so that the corner (A) is neatly covered. <IMAGE>
