Patent ID: 8242411

Claim:
Method of holding together electrically non-conductive objects, comprising: forming a stack of the electrically non-conductive objects; and applying to a side of the stack a static polarity with a planar electrode to electrostatically holding the objects together; wherein the planar electrode comprises a conductive layer, and a layer of semi-conductive material that covers the conductive layer and defines an outermost surface of the planar electrode; and wherein said applying comprises: connecting the conductive layer to a static electricity source, and directly contacting the semi-conductive material with said side of the stack to apply static electricity from the static electricity source, via the conductive layer to the semi-conductive material, and then to said side of the stack; wherein the semi-conductive material is elastically deformable, the semi-conductive material deforms upon direct contact with said side of the stack to ensure close contact and homogeneous transfer of the static electricity to the electrically non-conductive objects in the stack, the semi-conductive material springs back to an original form thereof when the direct contact between the stack and the semi-conductive material is ended, and said conductive layer is free of direct contact with the stack of objects when the semi-conductive material is in direct contact with said side of the stack.
