Description

Process for making printed cards

The invention relates to the manufacture of printed cards

Plastic material

especially of cards with a magnetic

Zone or a magnetic strip that identifies the user of this card, such as a cash or credit card Data carries.

According to the invention is a method for providing a printed Card with a magnetic zone or strip characterized by: Temporarily connecting a tape or piece of thermoplastic material with a magnetizable Covering with an intermediate, translucent strip of thermoplastic material, covering a rigid, printed card made of thermoplastic material with the intervening strip in the manner that the various Layers of thermoplastic material are superimposed, with the magnetizable coating facing outwards __2_

and applying sufficient heat and pressure to weld the various layers together thermoplastic material. In this way, the magnetic material is permanently bonded to the printed card. The pressure on the card is protected by superimposing a transparent layer of plastic material.

In a preferred embodiment of the invention, an uninterrupted PVC strip of printed cards is covered by an intermediate, translucent PVC strip to which spaced, parallel, magnetic PVC tapes are temporarily connected. The resulting laminated body is inserted into a heated press and heated to a temperature of 140-15O ⁰ C.

The individual cards are punched out of the superimposed strips during or after the strips are welded together. If punching is done after the strips are welded together, the composite is usually in first Ribbons cut. The cards are then punched out one at a time. This allows the punch to be aligned with each card and therefore reduces the risk of warped cards being produced. In detail, the position of the punching tool opposite to each card can be determined by a magnetic or opti-I see sensor, which is on the magnetizable strips responds so that the punch exactly with the bands

coincides with Oner than with the pressure). Thus the bands are i
precisely aligned with the edges of each card.

An embodiment of the invention will now be based on the drawing described. It shows:

Fig. 1 is a plan view of a credit or identity card,

Fig. 2 is a section along the line A-A through the in Fig.T shown card. .

A first, stiff, white PVC card 1 is printed back to back with ί

a similar card 2, each card having a print contains. One made of a PVC base material 5 under a magnetic one Coating 6 of the existing magnetic tape is briefly at the beginning connected to an intermediate, transparent PVC strip 4, which covers the first card 1. The second card 2 is also covered by a transparent PVC strip 3. The complete Laminate is then placed between the metal plates of a heating press to weld the various PVC layers together of the laminate used.

The heat and pressure are preferably sufficient to bring the magnetic coating 6 into one plane at the end of the bonding process the surface of the strip 4 so that the final card is repeatedly exposed to a magnetic recording or Playback head can be inserted without undue wear and tear on the heads or magnetic tapes.

Another transparent coating or lacquer is preferably applied the upper and / or lower surface of the laminated body 10

brought before or after briefly connecting the magnetic tape with the transparent strip 4 in between. A lacquer coating can also be applied to the magnetic tape before it is briefly connected to the strip in between. The varnish is then polished by pressing between the highly polished metal plates of the heating press during the time in which the laminated body is exposed to heat and pressure is exposed so that the resulting card has a glossy appearance.

For safety reasons, an additional one, only for ultraviolet or infrared radiation opaque print between the two cards 1 and 2 are covered.

The brief connection of the magnetic tape 5 with the intermediate, transparent strip 4 can be obtained by using an adhesive or by spot welding.

A continuous strip containing multiple cards can be formed in a single press then cut into ribbons perpendicular to the magnetic strips, each ribbon containing a single row of cards. The tapes will then passed a photoelectric device that scans the magnetic tapes and generates corresponding electrical signals. These signals actuate one adjustment punch, the two Punch holes in one wheel of the card, which will later be cut off The adjustment holes are thus made with the magnetic strips The tape is then stretched under an extension

stuff introduced. Aligning each card under the punch tool is controlled by the location of the adjustment holes.
