Claim 15:
16. A method, comprising:
(a) moving an applicator wheel through a supply of sealant, wherein the applicator wheel includes a plurality of footprints, each footprint comprising a trough and a backstop at a trailing end of thereof;
(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 a charge of sealant within the trough of each of the plurality of footprints as the applicator wheel moves through the supply of sealant;
(d) moving the plurality of footprints with the charges of sealant loaded therein toward a moving web of shingle stock;
(e) as the plurality of footprints are moved toward the moving web of shingle stock, inhibiting the charges of sealant from being displaced from the trailing ends of each of the plurality footprints with the backstop; and
(f) transferring the charges of sealant from the plurality of footprints to the moving web of shingle stock to form a self-seal strip comprising a plurality of dashes of sealant separated by spaces along the moving web of shingle stock;
wherein transferring the charges of sealant comprises contacting a surface of a first side of the moving web of shingle material with the footprints and distributing the charges of sealant along the surface of the first side of the moving web of shingle stock;
wherein during transfer of the charge of sealant to the surface of the first side of the moving web of shingle stock by the footprints 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 footprints and the surface of the first side of the moving web of shingle stock remain exposed to an external environment.
