Abstract
The invention discloses a light weight windowing safety line forge-preventing paper manufacturing method. It belongs to paper forge-preventing manufacturing method. It is aimed at the current technique defect of low weight, small thickness, bad windowing and embedding surface naked wire. The method includes the following steps: controlling cove depth of windowing stencil plate between 1.0 to 2.0mm; and its grade is between 5 to 20 degree; pressing copper web; preparing paper pulp; discharging safety line; manufacturing paper to form low weight forge-preventing paper with 65-85g/m<SUP>2</SUP> weight. It can extensively be applied to safety line windowing forge-preventing of low weight forge-preventing paper.
Description
Technical field
The present invention relates to a kind of false-proof production method of paper, particularly the preparation method of low quantitative opened window safety line anti-forge paper.
Background technology
Opened window safety line possesses the false proof secret mark (holographic icon) of organoleptic detection and the secret mark (magnetic code) that machine detects automatically simultaneously, its bulk information that adheres to can become the reliable condition that people tell truth from falsehood, and is favored day by day as a kind of novel and effective anti-counterfeiting technology so window.Windowing promptly is that certain of safety line simultaneously is interrupted not by the paper fiber-covered in the paper, requires that the face of windowing is clean and tidy, the face of imbedding is capped fully.And low quantitative paper sheets (65～85g/m
2) because of quantitatively low, thickness is little, very easily causing to window bad and imbed and shows line, paper strength is low simultaneously, causes brokenly paper and broken end easily during the safety line dispensing, influences ordinary production.
Summary of the invention
The making difficult point that purpose of the present invention is intended to carry out the safety line windowing technology at above-mentioned low quantitative anti-forge paper is with not enough, provides a kind of and windows that face is clean and tidy, the face of imbedding is by the preparation method of the low quantitative opened window safety line anti-forge paper of paper fiber-covered.
The objective of the invention is to realize by following technical proposals:
The preparation method of low quantitative opened window safety line anti-forge paper comprises and makes the masterplate of windowing, suppresses copper mesh, prepares paper pulp, discharges safety line, copies step such as paper that make when windowing masterplate, control masterplate concave depth is at 1.0～2.0mm, and the gradient is at 5 °～20 °.
Described cheque paper is quantitatively at 65～85g/m
2Between.
The invention has the beneficial effects as follows, when masterplate is windowed in making, the degree of depth that makes masterplate is between 1.0～2.0mm, the gradient is between 5 °～20 °, the position degree of depth of dispensing safety line is between 1.0～2.0mm on the copper mesh that such masterplate can guarantee to be suppressed, and the gradient is between 5 °～20 °, and such structure and method can make the low quantitative anti-forge paper that contains safety line be difficult for broken paper or broken end when safety line is discharged, behind the paper-making process, the face of windowing is clean and tidy, the face of imbedding is by fiber-covered.

Number in the figure, the 1st, the angle of gradient, the 2nd, the masterplate concave depth of windowing, the 3rd, the masterplate of windowing, the 4th, copper mesh, the 5th, the concaveconvex structure of the placement safety line that suppresses by the masterplate of windowing on the copper mesh, the 6th, safety line, the 7th, paper pulp pond, the 8th, splicing roller, the 9th, fourdrinier wire, the 10th, low quantitative anti-forge paper.
The specific embodiment
Further the present invention will be described below in conjunction with the drawings and specific embodiments:
Embodiment 1: as shown in Figure 1, the preparation method of low quantitative opened window safety line anti-forge paper has makes the masterplate of windowing, the compacting copper mesh, preparation paper pulp, the dispensing safety line, copy steps such as paper, when masterplate is windowed in making, by recess depths 2 is 1.0mm, the angle of gradient 1 is 5 ° the size design masterplate that goes out to window, by computer the scheme that designs is converted into the machine language that engraving machine can be discerned then, engraving cutter on the control engraving machine cuts out the masterplate of windowing according to the scheme feed of design, that produces windows the masterplate side view as shown in Figure 2, its recess depths 2 is 1.0mm, the angle of gradient 1 is 5 °, then with this masterplate on copper mesh 4, suppress place safety line concaveconvex structure 5 as shown in Figure 3, then as shown in Figure 4, prepare paper pulp and be positioned in the paper pulp pond, dispensing safety line 6 is close on the concaveconvex structure 5 of placement safety line of copper mesh 4, and copper mesh 4 rotating bands safety line through being placed with the paper pulp pond 7 of the paper pulp for preparing, insert fourdrinier wire 9 through splicing roller 8 again, producing at last quantitatively is 65g/m
2Low quantitative anti-forge paper 10.
Embodiment 2: other step and method such as embodiment 1, and the recess depths 2 of the masterplate of wherein windowing is 1.3mm, and the angle of gradient is 14 °, and the low quantitative anti-forge paper of producing at last quantitatively is 7g/m
2
Embodiment 3: it is 2.0mm that other step and method such as embodiment 1, the recess of the masterplate of wherein windowing attempt, and the angle of gradient is 20 °, and the low quantitative anti-forge paper of producing at last quantitatively is 85g/m
2
Claims (2)
1, the preparation method of low quantitative opened window safety line anti-forge paper, comprise and make the masterplate of windowing, suppress copper mesh, prepare paper pulp, discharge safety line, copy step such as paper, it is characterized in that: make when windowing masterplate, control masterplate concave depth is at 1.0～2.0mm, and the gradient is at 5 °～20 °.
2, the preparation method of low quantitative opened window safety line anti-forge paper as claimed in claim 1 is characterized in that: described cheque paper is quantitatively at 65～85g/m
