Embodiment 1

[0029] Embodiment 1: as figure 1 , a security thread anti-counterfeiting paper with a window in the middle, comprising a No. 2 web paper web 7, a No. 1 web paper web 8, and a security thread 2 between the No. 2 web paper web and the No. 1 web paper web, along the No. 1 web The longitudinal direction on the paper web is provided with at least one slender straight window 9 that runs through the two sides of the paper. The direction of the straight window is consistent with the direction of the security line. Coincident, the width of the straight-line window is smaller than the width of the safety line, the two long sides of the safety line are pressed by the No. 1 net paper, the rest of the safety line is exposed from the straight-line window, and the number of safety lines is at least one , the number of safety lines is consistent with the number of straight-line windows; the length of straight-line windows is equal to the length of safety lines; the width of safety lines is 3-...

Embodiment 2

[0038] Embodiment 2: The security thread anti-counterfeiting paper with the middle window in Embodiment 2 has the same structure as Embodiment 1.

[0039] The difference between the online forming system of embodiment 2 and embodiment 1 is that: the window opening device is a high-pressure water injection device; , a pressure regulator and a window opening nozzle are connected by water pipes, and the structure of other parts is the same as in Embodiment 1.

[0040] The manufacturing method is the same as that in Example 1, wherein the width of the window gap of the window opening nozzle is changed so that the window opening width after spraying No. 1 wet paper web is 3 mm, and the safety line width is 6 mm. Finally, the weight of the paper with the middle window is made to be 80g / m 2 .

Embodiment 3

[0041] Embodiment 3: processing structure such as figure 1 The anti-counterfeiting paper with the middle window opening security line adopts the online forming system in embodiment 2, and the manufacturing method is as embodiment 1, wherein the width of the window opening gap of the window opening nozzle is changed so that the window opening width after spraying the paper web is 5mm, which is safe. The line width is 8mm. Finally, the weight of the paper with the middle window is made to be 150g / m 2 .

Abstract

The invention discloses safety-line anti-counterfeiting paper with windows in the middle, a manufacturing method of the safety-line anti-counterfeiting paper and a meshing and forming system. The safety-line anti-counterfeiting paper comprises a second mesh paper web, first mesh paper webs and safety lines between the second mesh paper web and the first mesh paper webs. At least one long, thin and linear window which penetrates through two opposite sides of the paper is formed in the first mesh paper webs, the linear windows are parallel to the longitudinal direction of the first mesh paper webs, the center lines of the linear windows coincide with the central lines of the safety lines, the width of the linear windows is smaller than the width of the safety lines, and the number of the safety lines is same as the number of the windows. According to a manufacturing device of the safety-line anti-counterfeiting paper, a window forming device and a pay-off device of the safety lines are sequentially arranged in the positions, in front of a second mesh cage, of output paths of the first mesh paper webs. The manufacturing method of the safety-line anti-counterfeiting paper includes the steps that the windows are formed in the output paths of the first mesh paper webs, the safety lines are placed, and then the first mesh paper webs is compounded with the second mesh paper web. According to the novel structure of the anti-counterfeiting paper, the windows are continuously formed in the middle of the safety lines, and more anti-counterfeiting information can be borne.

Description

technical field [0001] The invention belongs to a papermaking technology, and in particular relates to an anti-counterfeiting paper with a middle window security thread, a manufacturing method thereof, and an online forming system. Background technique [0002] Security thread anti-counterfeiting paper refers to the paper with security thread fully embedded or half embedded (windowed) inside the base paper during the formation of the base paper to form an anti-counterfeiting function. Usually, the embedding method of the security thread anti-counterfeiting paper is different, and the appearance effect is different. Generally, the security thread is completely buried inside the paper, which is called fully buried security thread anti-counterfeiting paper, and the security thread is half-buried inside the paper, which is called window security thread anti-counterfeiting paper. The appearance of the current window security line paper is like a zebra crossing or a geometric fig...
