## Abstract

Systems and methods of applying self-seal strips of multiple different adhesives are disclosed. In one embodiment, two spaced apart spoked applicator wheel assemblies are positioned beneath a web of moving shingle stock such that each of the applicator wheels applies dots of different adhesives in an alternating pattern. In other embodiments, a layer of a second adhesive is deposited onto previously applied dots of a first adhesive to form layered adhesive dots with dual properties of both adhesives.

## Claims

wherein the first adhesive comprises a self-seal adhesive material having first adhesive properties and the second adhesive comprises a self-seal adhesive having second adhesive properties that are different from the first adhesive properties of the first adhesive; and
wherein application of the first adhesive and the second adhesive forms a multi-adhesive self-seal strip having different adhesive properties along the web of shingle stock.

### Claim 2 (depends on 1)

The system of claim 1 further comprising a stabilizer assembly located along the path of the web of shingle stock, the stabilizer assembly including a stabilizer wheel on one side of the web of shingle stock and aligned opposing supports on another side of the web of shingle stock.

### Claim 3 (depends on 1)

The system of claim 1 wherein the stabilizer assembly comprises a stabilizer wheel under which the web of shingle stock travels, flanked by a plurality of rollers over which the web of shingle stock travels.

### Claim 4 (depends on 1)

The system of claim 1 wherein first applicator assembly comprises a first applicator wheel having a plurality of spokes configured to apply the dots of the first adhesive, and wherein the second applicator assembly comprises a second applicator wheel configured to rotate in synchronization with the first applicator wheel to apply the second adhesive to the web of shingle stock between the dots of the first adhesive applied to the web of shingle stock by the first applicator assembly.

### Claim 5 (depends on 1)

The system of claim 1 wherein first applicator assembly comprises a first applicator wheel having a plurality of spokes configured to apply the dots of the first adhesive, and wherein the second applicator assembly comprises a second applicator wheel configured to rotate in synchronization with the first applicator wheel to apply the second adhesive to the web of shingle stock along the dots of the first adhesive applied to the web of shingle stock by the first applicator assembly.

### Claim 6 (depends on 1)

The system of claim 1 wherein the second applicator assembly comprises a puddle die in communication with an adhesive supply, the puddle die including a top portion configured to maintain a puddle of the second adhesive in a position adjacent the web of shingle stock such that the dots of the first adhesive engage the puddle of the second adhesive to pick up a layer of the second adhesive as the dots of the first adhesive pass along the puddle die.

### Claim 7 (depends on 1)

The system of claim 1, wherein the first applicator assembly comprises an applicator wheel having a plurality of spokes and an adhesive die configured to deposit the first adhesive onto each of the spokes of the applicator wheel.

### Claim 18 (depends on 11)

The method of claim 11, wherein the first applicator assembly comprises a first applicator wheel, and wherein the first applying step comprises applying the first adhesive to a surface of the first applicator wheel and rotating the surface of the first applicator wheel with the first adhesive applied thereto into engagement with the surface of the web of shingle stock.

### Claim 19 (depends on 18)
