Thereafter, the surface base material 1 is sent to the product folding and accumulating unit S26, and folded and accumulated from the horizontal perforation 13Y by the folding unit S261. The same effect as that of the first embodiment can be obtained by the manufacturing method of the delivery slip 10 as described above.

  In the first and second embodiments described above, the delivery slip 10 is manufactured as an example, and the surface base material 1 and the release paper 2 are subjected to predetermined processing in the production line of the previous process, The semi-finished product wound up as the surface base roll 1R and the release paper roll 2R is used in the production line of the delivery slip 10 shown in FIGS. 4 and 9, that is, this product production line. It is also possible to connect directly to this product production line and make it a production line with consistent flow work from raw materials to finished products. In the final process of the product production line, the products are folded and accumulated, but the products can be wound up as necessary.

  Moreover, although the planar shape pattern of the paste-killing portion 3 formed on the upper surface of the release agent layer 2A of the release paper 2 has been described as being all solid, in the present invention, the planar shape pattern of the paste-killing portion 3 is It can be changed as follows.

  FIG. 10 is a perspective view of a blindfolded postcard 20 manufactured by the method for manufacturing a blindfolded postcard according to the third embodiment of the present invention, and FIG. 11 is a YY sectional view of FIG. As shown in the figure, in this blindfolded postcard 20, a payment method, a card number, etc. are printed on the inner surface (the back side of the address description surface) of the main body 1X side of the surface base material (postcard mount) 1 together with the printing unit 24A for the name of the ordered product. A field for writing confidential information, that is, an information concealing portion 24B is printed, and the inner side of the end surface side of the surface base material 1 (side adjacent to the main body 1X) is formed through a folded portion 21 formed by perforations or the like. A folded piece 1Y that can conceal the information concealment portion 24B by being folded back is provided continuously. Note that the information concealment unit 24B may not be printed depending on the purpose or application. An adhesive layer 4, a paste-killing portion 3V, and a release paper 2 are provided in this order on the inner surface (the surface that conceals the information concealment portion 24B) of the folded piece 1Y. As shown in FIG. 11, two half slits 21A and 21B are engraved in the width direction on the end portion side of the folded piece 1Y.

For example, the formation of the planar shape pattern of the paste-killing portion 3V described above is the same as the paste described above. The purpose can be achieved by kill printing.

  When this blindfolded postcard 20 configured as described above is used, after peeling the release paper 2, the folded piece 1Y is folded back from the folded portion 21 and the inner surface is applied to the information masking portion 24B from the upper surface side. By pressing, the folded piece 1Y is temporarily bonded to the main body 1X, thereby concealing the information hiding portion 24B. When the folded piece 1Y that once conceals the information hiding portion 24B by temporary bonding is peeled off from the main body 1X, as shown in FIG. 13, the ends of the folded piece 1Y, that is, the half slits 21A and 21B are engraved. The peeled portion is delaminated, and the peeled portion is left on the inner surface of the main body 1X. As a result, according to the blindfolded postcard 20, the end of the folded piece 1Y does not re-adhere, and a trace remains, so that there is an advantage that the information concealment portion 24B is immediately opened.

  As described above, the method for forming the planar shape of the paste-killing portion 3V into a halftone dot pattern is applied, for example, to the manufacture of the delivery slip 10 in the first and second embodiments. The adhesive strength of the slip 10B is strong, and the adhesive strength of the delivery slip 10A that depends on the paste killing part 3 can be designed freely.

  In each of the first to third embodiments described above, the paste-killing portion is continuously formed with a predetermined width in the longitudinal direction of the release agent surface of the long release paper. In the invention, the invention is not necessarily limited to such an embodiment, and the above-described printing method is used, and the paste-killing portion is arranged in the longitudinal direction of the release agent surface of the long release paper, for example, a combination of rectangular shapes and various rectangles. Alternatively, it can be formed in a combination of shapes surrounded by a curve.

  Furthermore, the adhesive does not necessarily have to be applied so as to cover the entire paste-killing portion, and there is no problem even if there is an uncoated portion of the adhesive in a part of the paste-killing portion.

  The present invention is not limited to the delivery slips according to the first and second embodiments and the blindfolded postcards according to the third embodiment. In addition, for example, partial glue labels, tags, stickers, information concealment wrapping The present invention can be applied to the production of any sheet having a partial non-adhesive part (glue killing part) such as a sheet.
