PROBLEM TO BE SOLVED: To provide a "core" especially for packing a poster without any fold and for packaging the poster small without any fold, although two methods of rounding the poster into a paper cylinder and folding the same small are the main streams.SOLUTION: Damage such as a fold is not applied to a poster when a plate made of wood or resin and worked to have semicircle corners is used as a "core" to fold the poster around it. When an appendix poster is attached to a magazine, it can be slipped without any fold between books.SELECTED DRAWING: Figure 2 |
