Abstract
A device to automate the removal of a layer of opaque film applied to a card stock to obscure printed information residing underneath the film layer without introducing damage to the card stock itself that would significantly impair access to the printed information after such removal.
Claims22
A machine for removing a film layer region comprised of a border from a card stock comprising:
- a power roller;
- a stage plate, comprised of a planar surface that is parallel to the axis of the power roller whereby in use the card stock moves along the stage plate toward the power roller;
- a card position sensor that in use detects the condition that the border of the film layer is proximate to the position of the scraping tool edge;
- and
- a scraping tool comprised of an edge, said scraping tool moveable along an axis perpendicular to the plane of the stage plate, said scraping tool operationally coupled to an actuator that moves the scraping tool toward the power roller through an opening in the stage plate, said opening proximate to the power wheel and such movement made in response to the card position sensor detecting that the border of the film layer is proximate to the position of the scraping tool edge.

A method of removing a film layer region comprised of a border from card stock comprising:
- Passing the card stock across a scraping tool until a first predetermined position is reached;
- In response to the card stock reaching the first predetermined position, reversing the direction of the card stock until a second predetermined position is reached;
- In response to the card stock reaching the second predetermined position, reversing the direction of the card stock;
- Prior to the trailing edge of the card stock passing the scraping tool, moving the scraping tool away from the plane of motion of the card stock.
