| 摘要 |
A writing tablet is formed from a substantially continuous, fanfolded web of uniform width having transverse paths of weakness, along which the web can be torn evenly into individual sheets of uniform size. One face of the web bears a series of pressure-sensitive adhesive patterns, one pattern on each sheet, which pattern contacts the adhesive-bearing face of an adjacent sheet only in nonadhesive areas. The pressure-sensitive adhesive and nonadhesive areas are so prepared that each sheet can be cleanly peeled from the adjacent sheet without adhesive transfer, even after prolonged storage. After the tablet has been formed, its sheets can be conveniently and efficiently imprinted in a printer or copier and then returned to tablet form. |
