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.
Claims20
A system, comprising:
- a conveyance system along which a web of shingle stock is moved along a path;
- a first applicator assembly positioned along the path of the web of shingle stock;
- the first applicator assembly configured to apply a linear array of dots of a first adhesive to the web of shingle stock,
- wherein the first applicator assembly comprises a first applicator wheel, the first applicator assembly being configured to apply the first adhesive to a surface of the first applicator wheel and rotate the surface of the first applicator wheel with the first adhesive applied thereto into engagement with the surface of the web of shingle stock;
- and
- a second applicator assembly positioned along the path of the web of shingle stock downstream from the first applicator assembly;
- the second applicator assembly configured to apply a second adhesive to the web of shingle stock along the linear array of dots of the first adhesive;
- 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.

A method, comprising:
- moving a web of shingle stock along a path;
- applying a first adhesive to a surface of the web of shingle stock using a first applicator assembly,
- wherein the first applicator assembly comprises a first applicator wheel, and
- wherein the applying the first adhesive 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;
- and
- applying a second adhesive along a surface of the web of shingle stock using a second applicator assembly;
- wherein the first adhesive comprises a self-seal adhesive material having first adhesive properties and the second adhesive comprises another self-seal adhesive material having second adhesive properties that are different from the first adhesive properties of the first adhesive such that applying the first adhesive and the second adhesive forms a multi-adhesive self-seal strip having different adhesive properties along the web of shingle stock.
4 more elements
A method, comprising:
- moving a web of shingle stock along a path;
- applying a first adhesive to a surface of the web of shingle stock using a first applicator assembly,
- wherein the applying the first adhesive comprises applying dots of the first adhesive;
- and
- applying a second adhesive along a surface of the web of shingle stock using a second applicator assembly;
- wherein the applying the second adhesive comprises moving the dots of the first adhesive applied to the web of shingle stock along the second applicator assembly and picking up a layer of the second adhesive along the dots of the first adhesive,
- wherein the second applicator assembly comprises a puddle die configured to maintain a puddle of the second adhesive in a position adjacent the web of shingle stock,
- wherein moving the dots of the first adhesive applied to the web of shingle stock along the second applicator assembly further comprises moving the dots of the first adhesive through the puddle of the second adhesive, and
- wherein the first adhesive comprises a self-seal adhesive material having first adhesive properties and the second adhesive comprises another self-seal adhesive material having second adhesive properties that are different from the first adhesive properties of the first adhesive such that applying the first adhesive and the second adhesive forms a multi-adhesive self-seal strip having different adhesive properties along the web of shingle stock.
