1. A card cleaning mechanism, comprising:
- first and second cleaning roller assemblies, each cleaning roller assembly including;
a pair of cleaning rollers rotatably mounted on a turret body for rotation about respective longitudinal axes, each cleaning roller including a tacky outer surface, and the turret body being rotatable about a central longitudinal axis extending parallel to the longitudinal axes of the cleaning rollers; and
a cleaning tape assembly positioned adjacent the first and second cleaning roller assemblies, the cleaning tape assembly being configured to remove contaminants from the tacky outer surfaces of the cleaning rollers of each of the first and second cleaning roller assemblies.

Abstract
A cleaning mechanism for cleaning one or both side surfaces of a plastic card substrate prior to a processing operation occurring on the cleaned side surface. The cleaning mechanism is designed so that two cleaning rollers, one cleaning roller on a first cleaning station and one cleaning roller on a second cleaning station, are simultaneously cleaned by a single cleaning tape assembly.

8. A card cleaning module, comprising:
-
a card input through which a card to be cleaned is input into the module;
an input drive mechanism adjacent the card input for receiving a card through the card input and driving the card further into the module;
a card output through which a cleaned card is output from the module;
an output drive mechanism adjacent the card output for driving the cleaned card out of the module;
first and second cleaning stations disposed between the card input and the card output, the first and second cleaning stations each include;
a pair of cleaning rollers rotatably mounted for rotation about respective longitudinal axes and defining a nip therebetween through which the card passes, each cleaning roller including a tacky outer surface; and
a cleaning tape assembly positioned adjacent the first and second cleaning stations, the cleaning tape assembly being configured to remove contaminants from the tacky outer surfaces of the cleaning rollers of each of the first and second cleaning stations. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A card cleaning mechanism, comprising:
-
a cleaning roller assembly including a pair of cleaning rollers rotatably mounted for rotation about respective longitudinal axes and defining a nip therebetween through which a card passes for cleaning, each cleaning roller including a tacky outer surface; and
a cleaning tape assembly positioned adjacent the cleaning roller assembly and being configured to remove contaminants from the tacky outer surfaces of the cleaning rollers, wherein the cleaning tape assembly includes a backing roller having first and second ends, wherein the backing roller is supported by a bearing proximate the center of the backing roller between the first and second ends, and the backing roller is not supported by bearings at the first and second ends.

16. A card cleaning mechanism, comprising:
-
a cleaning roller assembly including a pair of cleaning rollers rotatably mounted for rotation about respective longitudinal axes and defining a nip therebetween through which a card passes for cleaning, each cleaning roller including a tacky outer surface; and
a cleaning tape assembly positioned adjacent the cleaning roller assembly and being configured to remove contaminants from the tacky outer surfaces of the cleaning rollers, wherein the cleaning tape assembly includes a supply roll of cleaning tape, an idler roller that rides against the surface of the supply roll, and an arm on which the idler roller is supported, the arm being pivotally mounted so that the idler roller can move toward the supply roll as the diameter of the supply roll decreases, and the arm is biased to move away from the supply roll.
