  • Patent number: 6237774
    Abstract: A method and combination for separating a singular element from a stack of contiguous similar stacked elements intended for individual use. A container for the stack is provided that has a layer of pressure sensitive adhesive firmly attached along one of its surfaces. To separate an individual element the stack is removed from the container, an outer or end element in the stack is pressed against the layer of adhesive, and the stack is pulled away from the layer of adhesive to separate at least a portion of the outer filter from the adjacent filter in the stack. The separated element is then peeled away from the layer of adhesive.

  • Patent number: 4255218
    Abstract: A device for applying a portion of a strip of adhesive releasably carried on a liner to one surface of a member. The device comprises a platen of a firm material having an edge surface with a radius dimension of less than about 1/8 inch and a mechanism for pulling the liner along a predetermined path with a portion extending around the edge surface of the platen and with the surface of the liner opposite the strip of adhesive contacting the edge surface.The surface of a member to which the strip of adhesive is to be applied is pressed against the strip of adhesive at the radiused edge surface and movement of the liner along the path will cause relative movement between the radiused edge surface and the surface of the member while transferring the strip of adhesive to the surface of the member and affording rotation of the member and resulting local deformation of the strip of adhesive at the edge surface so that the strip of adhesive can be applied in arcuate and linear patterns.
