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;
- 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;
- first applying a first adhesive to a surface of the web of shingle stock using a first applicator assembly;
- second, applying a second adhesive along the web of shingle stock;
- wherein the first adhesive and the second adhesive each comprise a self-seal adhesive material having different, cooperative adhesive properties;
- and
- wherein the first adhesive and the second adhesive are applied to the surface of the web of shingle stock so as to form a self-seal strip along the web of shingle stock.
