Patent ID: 7762939

Claim:
A method of making a fanfolded web label product from an elongated liner having a plurality of labels removably attached thereto at spaced locations along the length of the liner by a pressure-sensitive adhesive, said method comprising the steps of: advancing the liner with its attached labels along a path of travel; while the liner with its attached labels is advancing along said path, producing a series of transversely extending, alternately oppositely indented creases in the liner at predetermined spaces between the labels, each of said creases being at least substantially devoid of perforations; and folding the liner with labels attached in opposite directions about said creases to form a fanfolded stack having alternating, reversely folded plies, said producing step including passing the liner with attached labels between a first die roll and a first base roll oriented for indenting a crease in one direction in one side of the liner and then passing the liner with attached labels between a second die roll and a second base roll oriented for indenting a crease in the opposite direction in the opposite side of the liner, said die rolls each having a creasing blade and said base rolls each having multiple cushions for cooperating with the creasing blade in forming a crease, said base rolls each having a different circumference than the corresponding die roll and said blades and cushions being so positioned that the die rolls each make a single crease every multiple rotation of the die rolls.
