PRE-PREPARED PASTER PATTERNS Abstract of the Invention A pre-prepared paster pattern designed to effectively create a splice between the first web of a first roll of paper feeding into a high speed printing press and the leading edge of the second web of a second replacement roll of paper. The paster pattern comprises a first extensive paper layer having two generally triangularly shaped portions adapted on a first side to be adhesively connected to the end portion of the replacement roll and to a web portion of the replacement roll spaced from the end portion. An array of pressure sensitive adhesive layers are applied to the second and opposing side of the first paper layer and are adapted to adhere to the first web of the first roll while the first web is being fed into the high speed printing press. A very tacky adhesive layer is applied to the second side at the apex of each triangular portion and is protected by a removable cover or release paper layer. A second extensive cover or release paper layer overlies the first paper layer and is releasably adhered thereto. The second layer is designed to protect the pressure sensitive adhesive on the first layer during non-splicing operations whereby on removal of the second layer, the pressure sensitive adhesive is undamaged and has maximum adhesive properties so as to effect reliable splices between the webs of the rolls.
