Abstract
A method and apparatus for lifting the tabs of a protective seal with edges embedded in a laminate. The base of the device has an annular top having a plurality of cartridge receiving apertures spaced equally from one another. Each hole receives a tab engagement assembly comprising a cartridge, a spring, and a finger have an abutment surface. The finger is pivotally fastened at one end within the slot of the cartridge and is biased away from the cartridge by the spring. When the base is placed in proximate relationship with the laminate seal patch secured to the substrate, the rotating base causes the abutment surfaces of the fingers to drag across the periphery of the laminate seal in a circular motion. The stresses created on the tabs of the protective seal cause the embedded edges to be lifted. The lifted tabs are accessible to the end user and the protective seals may be easily peeled from the substrate when desired by the end user.
