Abstract

The present invention is to improve the tension and tear strength and the number of cut-off times when manufacturing a bundle of paper material that is used exclusively for tying 100 bills or the required number of bills to increase the convenience and functionality according to use Regarding the manufacturing method of the bundle of bills,

That is, 50 wt% of natural pulp is mixed with about 30 wt% of polyester twisted yarn having a thickness of 0.8 to 1.6 mm and a length of 10 to 15 mm, and then abaca pulp extracted from a banana tree is used as a binder material. Mix the weight percent and slowly mix for 4 to 6 hours, and pass the mixed mixture through a heating roller at about 300 ° C in the process of sheeting the mixed mixture through a bait of circular nets to transfer the polyester yarn to the pulp layer. By drying the fusion and then cutting to the required specifications to produce a strip, it is possible to improve the tensile strength, tear strength and the number of times cut.

The present invention relates to a method for manufacturing a banknote bundle strip, more specifically, the tensile strength and tearing strength and the number of cuts when manufacturing a bundle of paper material used exclusively to bundle banknotes of 100 sheets or as necessary It relates to a method of manufacturing a bundle of bills to improve the convenience and functionality according to use.

In general, banks that frequently withdraw banknotes and handle large quantities of banknotes bundle and distribute banknotes in 100-sheet units using narrow strips of paper to facilitate the calculation and storage of money. have.

Conventionally, the bands used to bind banknotes are cut into a certain width after producing papermaking through a conventional processing process using a raw material of paper mulberry pulp and natural pulp, which is a raw material of paper.

However, in recent years, the production of paper mulberry, which is a raw material of bundles, has sharply decreased and shortages have occurred. Therefore, the purchase of materials was made dependent on imports, and the supply and demand of materials were not only cumbersome, but also the tensile strength of the manufactured bundles was low. In the process of tying up the bills, the random cutting phenomenon was frequent, which lowered the work efficiency.

In particular, in the autumn, winter, and spring, when the air is dry, the moisture in the strip evaporates, and the tensile force acting in the longitudinal direction of the strip and the tear strength in the width direction of the strip and the band to bind the banknotes. There was a problem that the cutting phenomenon of the band occurs more frequently as the internal theft (frequency), etc., acting when overlapping and rotating, are weakened.

The present invention has been made in view of the problems of the conventional banknote band as described above, the object is to provide a method of manufacturing a banknote band that can improve the storage and durability without being affected by the outside air.

The present invention for achieving this purpose, after mixing about 30% by weight of polyester yarns having a thickness of 0.8 ~ 1.6mm and a length of 10 ~ 15mm to 50% by weight of natural pulp (abaca) extracted from banana trees (abaca ) The pulp is mixed with about 20% by weight of binder material and slowly mixed for 4 to 6 hours, and the mixed mixture is continuously passed through a heating roller at about 300 ° C. in the process of sheeting the mixed mixture through a bait of circular nets. By making the polyester yarn fused to the pulp layer and then chopped to the required specifications to produce a strip, it is characterized in that it is possible to improve the convenience and functionality according to the use by improving the tensile strength, tearing degree and the number of cuts.

Hereinafter, the manufacturing method of the banknote bundle of the present invention will be described with reference to the accompanying drawings.

Figures 1a and 1b shows a typical banknote bundle and its use example, the band 10 for binding the banknote is a tensile force (T) acting in the longitudinal direction and the tear degree (E) acting in the width direction and the banknote ( M is a criterion for determining the durability of the strip (B) to indicate the number of cut-outs acting when the belt 10 is superimposed and rotated to bind M).

Banknote bundle band of the present invention is a 50% by weight of natural pulp 0.8 ~ 1.6mm thick polyester yarn having a thickness of 10 ~ 15mm mixed with about 30% by weight of the abaca pulp extracted from the banana tree About 20% by weight of the binder material is mixed and mixed slowly for an elapsed time of 4 to 6 hours, and the mixed mixture is passed through a heating roller at about 300 ° C. in the course of sheeting by passing through a bait of a circular net polyester. The twisted yarn is fused to the pulp layer and manufactured by cutting it to the required standard.

The thickness of the polyester yarn is in the range of 0.8 to 1.6 mm and the length is in the range of 10 to 15 mm in order to satisfy the characteristics of the thin strip while smoothly dispersing when mixing with natural pulp.

In the drying process to obtain a sheet from the mixture, it is continuously passed through a heating roller at about 300 ° C., and the polyester twisted yarn in the sheet composition is fused to the thermal pulp layer. And it increases the number of times to cut off.

The following Table 1 shows the test results for the paper money bands of the conventional paper, the test institute is the technical standard, the test method is KSM7013-95, KSM7016-95, KSM7014-95, KSM7065-97, the test date The samples for testing as of March 31, 2002 to February 27, 2002 were four of commercially available products: A, B, C, and D.

              sample Paper (A) Paper (B) Paper (C) Paper (D) Test Items Basis weight (g / ㎡) 43.0 44.2 43.8 56.1 Tear strength (vertical. Gf) 68.4 72.0 44.4 51.1 Tensile Strength (P. kgf) 6.73 7.59 7.97 6.93 Number of festivals (length, time) 2300 1800 2600 420

However, the number of cutouts in the test items is the result of the test under 1kg load.

From the above results, it can be seen that the higher the tensile strength, the higher the number of cutouts. On the other hand, the higher the number of cutouts, the lower the tear strength. As a result, the conventional test samples had mutually conflicting vulnerabilities. In addition, due to the weakness of the tear strength, it was confirmed that the rate of breaking the band was high.

The following Table 2 is a test report of the banknote bundle band according to the production method of the present invention, the results were carried out under the same conditions as the test results of the control group.

Test Items unit Test result Test Methods The tensile strength horizontal KN / m {kgf / 15mm} 0.959 (1.47) KS M 7015: 2001 Vertical 3.60 (5.51) Tear strength horizontal mN {gf} 2028 (203) KS M 7016: 2001 Vertical 1148 (115) Basis weight g / ㎡ 46.3 KS M 7013: 2001 Number of cuts (1㎏ load) horizontal  time 45  KS M 7065: 2002 Vertical 30622

Therefore, looking at the test results of the present invention, it can be seen that it shows excellent tear strength and the number of times of break, although the tensile strength is comparable to and decreased compared to the prior art, it satisfies the excellent number of times of breakdown by the increase in tear strength. This can prevent the case of breaking the band arbitrarily.

Such a method of manufacturing a banknote band according to the present invention replaces a part of the material due to the depletion of natural pulses with polyester yarn to reduce the procedure and cost according to the material purchase, and to improve the preservation and durability of the banknote band. There is a concave that can be made, there is also an advantage that can increase the convenience and functionality according to the use of banknote bundles.
