ABSTRACT:
A method for substantially lifting dry-erasable marked images (4) from a whiteboard surface (2) includes providing a rolled transparent adhesive film sheet (6) for lifting the image, a rolled paper sheet (8) having a shade or color that is contrasting to the image (4) allowing for clearer viewing and easy handling of the lifted image when the sheets (6,8) are adhered together. The sheet rolls (24,26) are positioned, utilizing an elongated handling unit (12,36) that enables dispensing and joining of the sheets (6,8). An urging slit (16) is provided on the unit to urge consistent adherence together of the two sheets (6,8) when pulled through. At least one suction cup (30) is provided on at least one side of the handling unit (12,36) that is provided, in order to mount the unit (10,34) on or near the whiteboard surface (2). Permanent mounting and motorized operation alternatives and a surface cleaning method are provided.
