Taking encode " Shaanxi University of Science and Technology " as a example the invention will be further described.
Referring to Fig. 1, modern paper operation includes slurrying in stock tank, then embarks on journey on wet end 4, after squeezing, drying
Send into reel machine, a kind of digitlization encryption side becoming paper process based on the fiber that swirling eddy forms dot pattern of the present invention
Method, is one layer of web plate 2 of covering on wet end 4, above web plate 2, paper pulp flow direction is provided with guide rail 3, dot matrix coding controller 1 exists
Equally spaced it is uniformly distributed outside the endless track 7 of web plate 2 top, the direction of motion of endless track 7 and wet end 4 direction of motion one
Cause, the dot matrix coding controller 1 of endless track 7 lower section moves along guide rail 3 with endless track 7, drives dot matrix coding controller 1
Crawler belt motor 5 with drive wet end 4 wet end motor 6 speed identical it is ensured that shape after dot matrix coding wet web will not become
Shape, is so formed for the fiber figure of regular intertexture inside paper.
Referring to Fig. 2,3,4, dot matrix coding controller 1 is placed on the top of wet end 4, include input module, modular converter,
Memory module, processing module.Input module is connected with modular converter, for inputting dot pattern, modular converter and memory module
Connect, the dot pattern of input is converted into ranks dot array data (such as 16 × 16 dot array datas), processing module and storage
Module connects, and according to the pattern of input module conversion, can control the break-make of corresponding dot matrix air-flow on dot matrix coding controller 1.
The coding region of dot matrix coding controller 1 is rectangle, and width is 16 units, and length is the width of paper web, dot matrix
Coding controller is equally spaced uniformly distributed and circularizes, and multiple dot matrix coding controllers 1 are outside the endless track 7 above web plate 2
Portion is equally spaced uniformly distributed, and the direction of motion of endless track 7 is consistent with wet end 4 direction of motion, the dot matrix of endless track 7 lower section
Coding controller 1 moves along guide rail 3, and dot matrix coding controller 1 can control dot matrix coding control according to the pattern of input module conversion
The break-make of corresponding dot matrix air-flow on device 1 processed.When paper pulp flows through dot matrix coding-control region, the fiber in paper pulp is subject to air-flow dot matrix
Effect be gathered in below the web plate corresponding with dot matrix coding controller 1, inside paper, be so formed for regular intertexture
Fiber figure；
One layer of web plate 2 is coated with wet end 4, dot matrix coding controller 1 is placed on above web plate, prevents encoder from working
When, gather because the effect of air-flow makes slurry wad a quilt with cotton.
The course of work of dot matrix coding controller 1 is:

Root tuber controls the break-make of corresponding dot matrix air-flow on dot matrix coding controller 1 according to binary number, and the local fiber having air-flow assumes rule
Rule interweaves, and the local fiber alignment of airless is disorderly and unsystematic, has air-flow to represent " 1 ", airless represents " 0 ".
The processing module course of work is:
Will " Shaanxi University of Science and Technology " be converted into corresponding coding, processing module reads each binary digit, judges that whether this byte is
" 1 ", if " 1 ", then corresponding gas flow tube air-flow is opened；If not " 1 ", processing module reads digit and adds 1, controls adjacent gas
Flow tube；Processing module is back to first character section after having read all of byte.When paper pulp flows through dot matrix coding-control region, paper
Fiber in slurry is subject to the effect of air-flow dot matrix to be gathered in below the web plate corresponding with dot matrix coding controller 1, so in paper
Open the internal fiber figure being formed for regular intertexture.
