The invention relates to a protective elements used in banknotes, securities and identity documents to prevent counterfeiting and control authentication and which is a polymeric thread with additional protective features designed for introduction into the pulp in the paper manufacturing process.

In the protective element described in patent RU 2240926, features curly security thread of metallized polymeric material having a Central area and side elements in the form of wings, providing surround the introduction thread in the paper. This patent also describes a method of manufacturing paper with a protective element.

A disadvantage of the known technical solution is quite complex execution curly protective element by cutting the polymer film on the threads using laser irradiation, as well as technological difficulties arising from the operations of winding and unwinding threads with scalloped edges.

The technical result of the invention is to improve the technological properties of the protective element in the introduction of it into a paper weight and simplification of the manufacturing process of the protective element and paper. Another purpose of the invention is to provide a protective element that does not have cut-outs on the edges in the form of wings, satrudays the x winding thread. Protective effect yarns are due to deformation of a smooth straight edge and give it a volume that is three-dimensional threads.

This technical result is achieved in that in the method of manufacturing paper with a protective element for the authenticity control of security printing products, including the introduction of strands of polymeric film material having a Central part and edge areas on the grid the grid cylinder paper machine and subsequent dehydration in forming nasoni of paper pulp and pressing, according to the invention immediately before the introduction thread on the grid the grid cylinder is deformed, at least one of the edge zones of the thread.

The deformation is carried out by mechanical action or by combined mechanical and thermal effects.

The thread feature in the thickness of the paper web or the partial output of the deformed boundary zones on the surface.

Thread come in the form of a windowed thread with the formation of the Windows.

Protective element for the authenticity control of security printing products made in accordance with the proposed method.

Paper with a protective element for the authenticity control of security printing products are manufactured in accordance with the proposed method.

Protective element for which ontrol authentication security printing products made in the form of strands of polymer material with a Central part and edge zones, thus according to the invention, at least one of the edge zones of deformed thread.

In the protective element of polymeric material is metallized.

Polymeric material made from portions of demetallization.

The width of the deformed zone of the region is from 1 to 3 mm.

The width of the undeformed Central zone of the yarn is not less than 2 mm.

The thickness of the yarn is from 12 to 50 microns.

The amplitude of the line edges, obtained by deformation, ranges from 100 to 1000 microns.

Regional zones of deformed continuously along the entire length of the thread.

Edge areas are deformed with regular or irregular frequency along the length of the thread.

The protective element is made with fluorescent and/or Zlatopramen, and/or holographic images, and/or magnetic coating located over the entire surface of the thread or on part of the surface.

Unlike pleasego analogue of the claimed group of inventions in patent RU 2240926, which does not include the deformation of the side elements of the thread before its introduction in the paper, the proposed application for the invention is made of the deformation of the edges of the flat yarn with getting to the introduction of the paper surround the filament due to a certain amplitude of oscillation of the edge threads in the warp, while the edge of the thread used even without a cut. Thus, the deformed, the least one of the edge zones of the thread before its introduction on the grid mesh of the cylinder.

The essence of the invention is shown on the following drawings:

Figure 1 - image of the protective element.

Figure 2-5 - different arrangement of the protective element in the page.

Figure 1 shows the protective element, which is a polymeric thread 1 with Central undeformed area 2 and the deformed boundary zones 3, resulting from or by mechanical joint mechanical and thermal effects.

The deformed edge areas 3 thread 1, is made of a polymeric film such as polyethylene terephthalate, have a width of from 1 to 3 mm and are arranged continuously along the entire length of the thread or with a regular or irregular frequency along the length of the thread. The width of the Central undeformed zone 2 is preferably from 2 mm Thick filament ranges from 12 to 50 microns.

The amplitude of the line to the edge of the protective element is from 100 to 1000 microns.

When using a metallized polymeric material it may contain areas of demetallization. To improve the protective properties of the protective element can be performed with fluorescent and/or Zlatopramen, and/or holographic images, and/or magnetic coating located over the entire surface of the thread or on part of the surface.

On Phi is .2 shows the location of three-dimensional protective element in paper 4 in case when he is completely in the thickness of the paper. When considering paper with such a protective element on clearance observed shaped edge 3 thread 1 formed due to its deformation due to mechanical and thermal loading.

Figure 3 shows the three-dimensional location of the protective element in paper 4 in the case when the Central part 2 thread 1 is entirely in paper 4, and the deformed region 3 is partially exposed to the surface, forming a wavy edge of the protective element.

Figure 4 and figure 5 shows the location of three-dimensional protective element in paper 4, entered on the principle of "diving" security thread 1.

Figure 4 shows the location of the protective element in paper 4 in the case when the Central undeformed part 2 of a width not less than 2.0 mm occasionally comes to the surface, the length of the "window" is from 5.0 to 10.0 mm, the distance between "Windows" is from 5.0 to 10.0 mm, and the deformed region 3 are located on the surface of the paper along the entire length of the thread 1.

Figure 5 shows the location of the protective element in paper 4 in the case when the Central undeformed part 2 thread 1 and the deformed zone 3 come to the surface (the length of the "window" of 5 to 10 mm), a "window" periodically repeated at a distance of 5 to 10 mm

A method of manufacturing a three-dimensional security threads is that flat is vohmina thread 1 is passed through the device, consisting of two pairs of rotating together bevel gears located at a certain angle in one axis, while deformed, at least one edge of the thread, and the Central portion 2 having a width of not less than 2 mm, remains flat and undeformed. To enhance the effect of the gear can be heated to a temperature of from 50°to 100°that increases the plasticity of the polymer material in the zone of deformation. As a result of this security thread becomes three-dimensional and the introduction of the paper can act on both the surface of the treated paper. The warp yarn is made directly before her introduction to grid grid cylinder paper machine. Carry out the forming and dewatering nasoni of paper pulp on the grid mesh of the cylinder with subsequent pressing.

The protective element, is proposed as the invention may be fully introduced in the paper or in part, for example the undeformed area is completely within the thickness of the paper, and the deformed region are located on the surface.

It is also possible introduction of the item offered in the invention, on the principle of "diving" security threads, namely, when the thread is located in the thickness of the paper comes to the surface after a certain period, forming a so-called "window".

Deformation protect the Noah polymer strands at the edges by mechanical and/or thermal effects produced directly before inserting it in the paper, that improves the processing properties of the protective element, as it does not require technological operations of winding and unwinding volumetric security threads, which is unstable technological operations.

The proposed protective element due to the three-dimensionality of security threads can improve its protective properties and to provide greater variance posting threads in the paper. This protective element can be used in various kinds of security printing products.
