A pocket-folder comprises a sheet of cardboard 2 folded along a crease line 2a, the sides of the pocket being formed by folded strips 4. To assist in production, the strips are glued along the whole length of the sheet 2 while flat, and the unwanted folds are glued together at 8, 15. One half of the sheet 2 may be extended to form a fold-over closing flap. <IMAGE> |
