Claim 8:
9. A method, comprising:
(a) moving an applicator wheel through a supply of sealant, wherein the applicator wheel includes at least one footprint comprising a backstop positioned at a trailing end thereof and configured to pick up a charge of sealant therein;
(b) moving a web of shingle stock in a horizontal direction;
wherein the applicator wheel is configured to rotate along an axis perpendicular to the horizontal direction of the moving web of shingle stock;

(c) loading the charge of sealant within the at least one footprint as the applicator wheel moves through the supply of sealant;
(d) moving the at least one footprint and the charge of sealant loaded therein toward the moving web of shingle stock;
(e) inhibiting, with the backstop, the charge of sealant within the at least one footprint from being displaced from the trailing end of the at least one footprint during movement of the at least one footprint from the supply of sealant toward the moving web of shingle stock;
(f) applying the charge of sealant to the moving web of shingle stock;
wherein applying the charge of sealant comprises contacting a surface of a first side of the moving web of shingle material with the at least one footprint and distributing the charges of sealant along the surface of the first side of the moving web of shingle stock;
wherein during application of the charge of sealant to the surface of the first side of the moving web of shingle stock by the at least one footprint of the applicator wheel, areas of a surface of a second side of the moving web of shingle stock directly opposite points of transfer between the at least one footprint and the surface of the first side of the moving web of shingle stock remain exposed to an external environment; and
(g) repeating steps (a)-(f) to form a self-seal strip of sealant along the moving web of shingle stock.
