Abstract: A tape structure and/or closure system particularly useful with cylindrical insulation segments for pipes. The tape structure provides both a temporary and a permanent closure. The tape structure includes a substrate and a layer of pressure sensitive adhesive disposed on both sides of the substrate. One of the layers of pressure sensitive adhesive is covered by a release liner, while the other layer of pressure sensitive adhesive is exposed. The exposed layer of pressure sensitive adhesive is applied to one of either the underside of a flap covering a slit in the insulation jacket, or to the outer surface of the insulation jacket. The release liner is divided into two portions, one of which is narrow with respect to the other portion. The narrow portion of the release liner is removed, and a narrow strip of the second layer of pressure sensitive adhesive is attached to the other of either the outer surface of the jacket, or the underside of the flap to form a temporary closure.

The tape applicator also includes a pressure roller for urging the tape onto the member, and for urging the member into engagement with the drive roller. A guide roller guides the location of the tape to the member so that it is applied to the proper location. A cutting mechanism is automatically actuated for cutting the tape adjacent the trailing end of each member at a desired location. The cutting mechanism is actuated by a switch which is engaged by the member.

Abstract: A ferromagnetic foil carrying a layer of a pressure sensitive adhesive for adhesive attachment to a printing plate to be used in a letterpress or flexographic printing operation. The ferromagnetic foil preferably is formed of a cold rolled steel having a thickness in the range of from about 0.001 inch to about 0.007 inch. The metal foil allows the printing plate to be adhered to the outer surface of a magnetized printing cylinder due to the magnetic attraction between the printing cylinder and the ferromagnetic foil. If the printing cylinder is not magnetized, but is formed of a ferromagnetic material, a flexible magnetic pad is applied to the outer surface of the cylinder, and the ferromagnetic foil-backed printing plate is then placed on the flexible magnetic pad.

Abstract: A method and apparatus for protecting removable markings on an optical lens during grinding thereof to a desired prescription. A mask is placed over the markings prior to application of an adhesive tape, to which a low temperature alloy block is bonded for holding of the lens during grinding. The mask preferably covers only the markings, and is transparent to allow alignment thereof. Preferably the mask is held in place on the lens surface without the use of an adhesive, although a low tack adhesive may be used which does not remove the markings when the mask is peeled away from the lens. A preferred material for the mask is a static cling vinyl.
