Abstract
Abstract A tile product and a method for preparing an adhesive coated tile product with a protective sheet thereon which sheet is removed when the tile products are installed. The uncoated tile products are moved from a stack in succession by a conveyor at a constant speed and in uniformly spaced relationship and an adhesive coated web having an adhesive patch with an area less than the area of the tile product is applied over the moving tile products and bonded thereto. This web is then severed between each adjacent tile product by a cutting knife in such a manner as to provide an overlap of the web and the resultant adhesive bonded to the tile is set back from the tile edges.
