Abstract

A magnetically encoded plastic card production system is provided which includes a supply mechanism for supplying a series of blank plastic cards. An encoder is operatively coupled to the supply mechanism which encodes a magnetic strip on each card. A separating mechanism is operatively coupled following the encoder which has a roller surface for adhesively attracting loose particles from a surface of each card. A design placing mechanism is operatively coupled immediately following the separating mechanism which places a graphic design on each card. In this arrangement, the loose particles are separated from each card subsequent to encoding the magnetic strip on each card and prior to placing the graphic design on each card. A collecting mechanism is operatively coupled to the design placing mechanism which collects each card after each card has passed through the encoder, separating mechanism, and design placing mechanism. A method for producing magnetically encoded plastic cards is also provided.

Claims

1. A magnetically encoded plastic card production system, comprising:

(a) supplying means for supplying a series of blank plastic cards;

(b) encoding means, operatively coupled to the supply means, for encoding a magnetic strip on each card;

(c) separating means, operatively coupled following the encoding means, having a roller surface for adhesively attracting loose particles from a surface of each card;

(d) design placing means, operatively coupled immediately following the separating means, for placing a graphic design on each card such that the loose particles are separated from each card subsequent to encoding the magnetic strip on each card and prior to placing the graphic design on each card; and

(e) collecting means, operatively coupled to the design placing means, for collecting each card after each card has passed through said encoding means, said separating means, and said design placing means.

2. The card production system of claim 1 further comprising a central system controller means for controlling operations of said encoding means, said separating means, and said design placing means.

3. The card production system of claim 1 further comprising embossing means, operatively coupled to the design placing, for embossing alphanumeric characters on each card after said design placing means places the graphic design.

4. The card production system of claim 1 wherein said design placing means comprises:

(d) (i) feeding means for feeding each card along a work feed path;

(d) (ii) printing means, positionable adjacent the work feed path, for printing a predetermined pattern as the graphic design on each card; and

(d) (iii) aligning means for precisely aligning said printing means with respect to said feeding means so that said printing means is adapted to bear against each card at a constant pressure.

5. The card production system of claim 1 wherein said separating means comprises:

(c)(i) cleaning means for collecting loose particles from each card through the use of at least one engaging surface adapted for engaging a particular surface of each card to be cleaned, the at least one engaging surface having means for attracting loose particles from the particular surface of each card to be cleaned, the feeding means being adapted for feeding each card from said supplying means to said cleaning means along the work feed path; and

(c)(ii) removing means for removing collected particles from said cleaning means.

6. The card production system of claim 4 wherein said feeding means comprises a first pair of printer feed rollers;

a second pair of printer feed rollers aligned with the said first pair of printer feed rollers along the work feed path; and

means for driving said first and second pairs of printer feed rollers.

7. The card production system of claim 4 wherein said printing means comprises a resistance type thermal printer.

8. The card production system of claim 7 wherein said thermal printer comprises a print head element, positionable adjacent the work feed path, which has a thermal print line thereon facing the work feed path, said thermal printer further comprising foil feeding means for feeding a thermal printing foil between said thermal print line and the work feed path.

9. The card production system of claim 8 wherein said thermal printing foil has a first carrier layer, a backing layer on said carrier layer for contacting said thermal print line and a pigmentation layer on the side of said carrier layer opposite said backing layer.

10. The card production system of claim 9 wherein said pigmentation layer includes a thermal transfer ink of the type which reacts exothermically to heat applied by said thermal print line, whereby printing the predetermined pattern may be effected without melting any portion of said printing foil.

11. The card production system of claim 8 wherein said thermal print line has a multiplicity of resistive elements therein which are selectively actuatable to print the predetermined pattern as the graphic design on each card.

12. The card production system of claim 8 wherein said foil feeding means comprises foil supplying means for supplying said thermal printing foil;

foil storing means for storing said foil after use; and

means for guiding said foil from said foil supplying means to a path between said thermal print line and the work feed path and into said foil storing means.

13. The card production system of claim 12 wherein said foil feeding means further comprises cassette means for housing and supplying said foil supplying means and said foil storing means.

14. The card production system of claim 5 wherein said cleaning means comprises at least one cleaning roller having an outer surface for engaging the surface of each card to be cleaned.

15. The card production system of claim 14 further comprising means for driving said at least one cleaning roller, thereby aiding propulsion of each card along the work feed path.

16. The card production system of claim 14 wherein said removing means comprises a stripping element having stripping means thereon for stripping particles from said at least one cleaning roller, and means for selectively causing engagement between said at leas one cleaning roller and said stripping means.

17. A method for producing magnetically encoded plastic cards, comprising the steps of:

(a) supplying a series of blank plastic cards having an encodable magnetic strip;

(b) encoding the encodable magnetic strip on each card;

(c) adhesively attracting, following the encoding step, loose particles from a surface of each card;

(d) placing, immediately following the attracting step, a graphic design on each card such that the loose particles are separated from each card subsequent to encoding the magnetic strip on each card and prior to placing the graphic design on each card; and

(e) collecting each card after each card has been processed by steps (a) through (d).

18. The method of claim 17 further comprising the step of embossing alphanumeric characters on each card after said design placing step.
