Abstract
Abstract The process involves the unwinding of a roll of paper and coating it with an adhesive which is subsequently dried. The paper is then passed through an open press and is joined to a tile which is held by one platen of the press in the center of a rule die on the platen. The press closes and permits the rule die to cut a blank of paper from the roll of paper and, at the same time, press the blank of paper against the tile. Subsequent removal of the paper will leave the adhesive coating on the tile and permit the tile to adhere to any desired surface. The apparatus herein carries out the above process.
