Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of manufacturing magnetic cards such as bank cards and credit cards.The structure and manufacturing method of conventional magnetic cards are made from sheets of opaque vinyl chloride, etc. of about 550 μm, for example. After printing a predetermined pattern 2 on both sides of the card base 1, an adhesive 3 is applied to the surface of the printed layer and bonded under heat.
An oversheet 4 of vinyl monide film was attached to the film, and then a magnetic tape 5 was placed in a striped pattern.
Finally, both sides of the base were heated and pressed with mirror plates, and the magnetic tape 5 was embedded in the oversheet 4 to obtain a magnetic card.

Therefore, since the card base 1 is made of a fairly thick material, rotary printing is impossible, and the manufacturing speed is slow, making it impossible to obtain the positional accuracy of designs, magnetic tape, etc., resulting in poor yields and high manufacturing costs. There were other drawbacks.

The present invention, which was conceived in view of the oblique point, will be explained with reference to the drawings based on one embodiment.

The oversheet 6 has a thickness of 0.14 m4 with perforations 7 perforated at predetermined positions.As for the material, various thermoplastic resins can be used depending on the purpose of use of the card, but considering processability. In consideration of this, hard vinyl chloride is suitable.

Still, the perforation 7 is formed by a punching unit (not shown) consisting of a male roll and a female roll during extrusion molding of the oversheet 6.
It is appropriate to drill holes at predetermined positions.

1. On the thus obtained oversheet 6, as shown in FIG. 2, a desired pattern is formed by a four-color letterpress printing machine C using rotary reciprocation and reverse printing simultaneously on the front and back sides using a UV system a.

That is, the designs to be formed on the front and back sides of the magnetic card are printed at predetermined positions on the back side of the magnetic card using a rotary printing press C equipped with a UV dryer.

Note that the printing speed at this time was 30 revolutions/minute.

Next, magnetic material is completely applied to the tape base via a take-up roll unit (d) consisting of a male roll and a female roll, and the tape base is coated with magnetic material. Width: 6.5 ml Thickness: 28
Transfer the μ magnetic data m) 8 with a guided transfer roll at about 130°C,
Thereafter, the magnetic tape 8 is embedded into the oversheet 6 using a pressure roll (see FIG. 3).

Then, a crease e is made to bend the oversheet 6 where the magnetic tape is embedded.

Next, for example, the thickness obtained by extrusion is 0.5 m/
A rolled-up base sheet 9 (for example, a bone white sheet) with a width of about 225 m/m is folded back with the surface pattern 12 while folding back the oversheet 6 in which the magnetic tape 8 is embedded along the stripes e.
f. Layer them so that they are sandwiched from both the front and back sides so that the back pattern 12b contacts the base sheet 9 (see FIG. 2B).

After this, in order to take the timing, the superposition device 11
The three feeds from 1 to 3 are sent at once to the next high-frequency molding process.

In the next high-frequency molding process, the high-frequency output increases to 50 W.
At a pressure of 25 tons, a mold made of stainless steel with a chrome-plated surface was made into a caterpillar shape, and Shimono 15 was used.
It is necessary to heat it for about 7 seconds using a high frequency press machine 13.

Further, in this step, it is necessary to install a cooler 14 to perform heating and cooling separately.

At this time, approximately 10 seconds is required as a cooling time.

After that, the sensor-equipped punching device 19
Then, the printing position and the position of the magnetic tape are detected, the magnetic card 20 is punched out, and the remaining portion is wound up, completing the entire process.

. The magnetic card according to the present invention is produced by using a rotary printing machine to reversely print the front and back sides simultaneously on an oversheet with perforations punched at predetermined positions, and then using a heated transfer roll to apply magnetic tape to the predetermined positions in the form of stripes. The oversheet with magnetic tape obtained in this way is superimposed on the base sheet so that the printed pattern is in contact with the base sheet, and the caterpillar method is applied using the frictional heat generated by high frequency current. After molding with a mold,
Because it is obtained by punching out the magnetic tape by detecting the position of the magnetic tape and the printing position using a sensor through a take-up roll unit, it has better printing suitability than conventional methods in which designs are printed directly on the substrate. Moreover, since printing is performed on the oversheet on both sides at the same time, it is suitable for work.

The perforations make it easier to register the printed pattern and the magnetic tape, increasing positional accuracy.

In addition, the oversheet material, dimensions, and
The printing method, press conditions, etc. are not limited to these.
