Embodiment 1

[0033] Embodiment 1: as figure 1 and 5 As shown, a papermaking net cage adopting a paper-cut pattern as a watermark sheet includes a paper net 1 and a watermark sheet 2 arranged on the paper net 1. The watermark sheet 2 adopts a paper-cut pattern, and the paper-cut pattern is a positive image. The thickness of the watermark sheet 2 is 0.1 mm to 2 mm, and the watermark sheet is glued and welded on the surface of the paper net, wherein the watermark sheet 2 is made of metal material or non-metal material, and the non-metal material includes flexible material , when the watermark sheet is made of a metal material, the surface of the watermark sheet 2 is plated with a silver layer to facilitate welding, and the silver plating treatment can be carried out before cutting the watermark sheet, and if the process permits, it can also be plated after cutting. Silver: Traditional watermark 4 matched with watermark sheet 2 is pressed on the surface of said paper net 1, so that paper-cut ...

Embodiment 2

[0043] Embodiment 2: as figure 2 and 5As shown, a papermaking net cage adopting a paper-cut pattern as a watermark sheet includes a paper net 1 and a watermark sheet 2 arranged on the paper net 1. The watermark sheet 2 adopts a paper-cut pattern, and the paper-cut pattern is a positive image. The thickness of the watermark sheet 2 is 0.1 mm to 2 mm, and a recessed area 3 is arranged on the surface of the paper web 1, and the watermark sheet 2 is arranged in the corresponding recessed area 3, and the recessed depth of the recessed area 3 is smaller than that of the watermark The thickness of the sheet 2, that is, part of the watermark sheet is placed in the recessed area, while the other part protrudes from the surface of the paper web. The outline of the outer edge of the recessed area 3 is equal to the outer edge of the watermark sheet 2. Wherein, the watermark sheet 2 is made of metal material or non-metal material, and the non-metal material includes flexible material. If...

Embodiment 3

[0054] Embodiment 3: as image 3 and 5 As shown, a papermaking net cage adopting a paper-cut pattern as a watermark sheet, the depth of the depression in the recessed area 3 is equal to the thickness of the watermark sheet 2, that is, all the watermark sheets are placed in the recessed area, and the upper surface of the watermark sheet is in contact with the paper net. surface flush. Other structures and manufacturing steps are basically the same as in Example 2.

[0055] The watermark paper made by using the paper-making net cage of the watermark sheet with the paper-cut pattern as the positive image, the sizing thickness of the pattern part of the watermark sheet and the corresponding part of the non-watermark sheet are basically the same, and the gray scale of the paper itself is presented in the paper. However, there will be an obvious dividing line on the edge of the watermark sheet, which will clearly separate the corresponding part of the non-watermark sheet in the pa...

Abstract

The invention discloses a papermaking net cage adopting a paper-cut pattern as a watermark piece. The papermaking net cage comprises a paper net and the watermark piece arranged on the paper net, wherein the watermark piece adopts the paper-cut pattern; the paper-cut pattern is a positive pattern or a negative pattern. The paper-cut pattern is adopted as the watermark piece on the paper net, a paper cutting technology is combined with a watermark papermaking technology, sizing water filtering is realized by utilizing the hollowed-out characteristic of the paper-cut pattern, convenient adhesion and welding connection positioning is realized through the characteristic that the pattern is integrally connected, and the technological difficulties of spot welding and water filtering are effectively solved; moreover, by adopting the technology, peculiar watermark pattern paper with strong traditional culture further can be designed and manufactured. The technology does not need to be combined with a traditional net pressing watermark technology, watermark paper with a coordinated complete pattern can be designed and manufactured in general, the area of the whole pattern can exceed 60 mm * 60 mm, and the watermark effect is peculiar, so that the watermark paper has a new anti-counterfeiting characteristic.

Description

technical field [0001] The invention belongs to the technical field of anti-counterfeit papermaking, and in particular relates to a papermaking net cage using a paper-cut pattern as a watermark sheet. Background technique [0002] In the production of anti-counterfeiting paper, some kind of thin sheet material is used to make a pattern, stick it on the paper-making net cage, and then copy the paper with watermark pattern. This kind of watermark is called patch watermark, and the pattern made of thin sheet material is called for the watermark. [0003] The existing high-transparency white watermark technology in China, because it has not solved the difficulties of water filtration and easy fixing and welding, is now limited to letters, numbers and a watermark pattern that are made of metal materials on the paper net and welded in advance. Smaller (generally less than 6cm 2 ), it is not possible to produce regular-sized watermark patterns with coordinated artistic effects. ...
