Abstract

An applicator for dispensing multiple adhesives on a substrate is disclosed. The applicator includes a manifold that includes a first dispensing module and a second dispensing module. The first dispensing module has a first inlet and a first nozzle. The first inlet receives a first adhesive and the first nozzle applies the first adhesive to the substrate. The second dispensing module is adjacent the first dispensing module and has a second inlet and a second nozzle. The second inlet receives a second adhesive that is different from the first adhesive. The second nozzle applies the second adhesive to the substrate.

First claim

What is claimed is:

1. An applicator for dispensing multiple adhesives on a substrate, the applicator comprising:
a manifold comprising:
a first dispensing module having a first inlet and a first nozzle, the first inlet configured to receive a first adhesive, and the first nozzle configured to apply the first adhesive to the substrate; and
a second dispensing module adjacent the first dispensing module, the second dispensing module having a second inlet and a second nozzle, the second inlet configured to receive a second adhesive that is different from the first adhesive, and the second nozzle configured to apply the second adhesive to the substrate;

a first pump having an inlet and an outlet, the first inlet of the first dispensing module being configured to receive the first adhesive from the outlet of the first pump; and
a first pressure feed block having an inlet and an outlet, the inlet of the first pressure feed block being in fluid communication with a source of the second adhesive, the second inlet of the second dispensing module being configured to receive the second adhesive from the outlet of the first pressure feed block.

2. The applicator of claim 1 , wherein the inlet of the first pressure feed block comprises an input fitting that is configured to be connected to a hose that is in fluid communication with the source of the second adhesive.

3. The applicator of claim 2 , wherein the second adhesive in the hose is pressurized.

4. The applicator of claim 2 , wherein:
the manifold has a manifold input that is configured to receive the first adhesive from a source of the first adhesive, and
the inlet of the first pump is in fluid communication with the manifold input to receive the first adhesive.

5. The applicator of claim 4 , wherein the manifold input comprises an input fitting that is configured to be connected to a hose that is in fluid communication with the source of the first adhesive.

6. The applicator of claim 5 , wherein the first adhesive in the hose is unpressurized.

7. The applicator of claim 4 , wherein:
the manifold further comprises a third dispensing module having a third inlet and a third nozzle, the third inlet configured to receive the first adhesive, and the third nozzle configured to apply the first adhesive to the substrate,
the manifold further comprises a second pump having an inlet and an outlet, and
the third inlet of the third dispensing module receives the first adhesive from the outlet of the second pump.

8. The applicator of claim 7 , wherein:
the manifold defines a supply channel that is in fluid communication with the manifold input, the inlet of the first pump, and the inlet of the second pump,
the inlet of the first pump receives the first adhesive from the supply channel, and
the inlet of the second pump receives the first adhesive from the supply channel.

9. The applicator of claim 1 , wherein the second dispensing module is directly adjacent the first dispensing module.

10. The applicator of claim 1 , wherein the manifold is a unitary manifold.

11. An applicator for dispensing multiple adhesives on a substrate, the applicator comprising:
a manifold comprising:
a first dispensing module having a first inlet and a first nozzle, the first inlet configured to receive a first adhesive, and the first nozzle configured to apply the first adhesive to the substrate;
a second dispensing module adjacent the first dispensing module, the second dispensing module having a second inlet and a second nozzle, the second inlet configured to receive a second adhesive that is different from the first adhesive, and the second nozzle configured to apply the second adhesive to the substrate; and
a third dispensing module having a third inlet and a third nozzle, the third inlet configured to receive the first adhesive, and the third nozzle configured to apply the first adhesive to the substrate;

a first pump having an inlet and an outlet, the first inlet of the first dispensing module configured to receive the first adhesive from the outlet of the first pump;
a second pump having an inlet and an outlet;
a manifold input that is configured to receive the first adhesive from a source of the first adhesive;
a supply channel that is in fluid communication with the manifold input, the inlet of the first pump, and the inlet of the second pump;
a recirculation channel; and
a recirculation pump having an inlet and an outlet, the recirculation pump being different from the first pump and the second pump,
the third inlet of the third dispensing module being configured to receive the first adhesive from the outlet of the second pump,
the inlet of the first pump being in fluid communication with the manifold input to receive the first adhesive,
the inlet of the first pump being configured to receive the first adhesive from the supply channel,
the inlet of the second pump being configured to receive the first adhesive from the supply channel,
the inlet of the recirculation pump being in fluid communication with the recirculation channel, and
the outlet of the recirculation pump being in fluid communication with the supply channel.

12. An applicator for dispensing multiple adhesives on a substrate, the applicator comprising:
a manifold comprising:
a first dispensing module having a first inlet and a first nozzle, the first inlet configured to receive a first adhesive, and the first nozzle configured to apply the first adhesive to the substrate; and
a second dispensing module adjacent the first dispensing module, the second dispensing module having a second inlet and a second nozzle, the second inlet configured to receive a second adhesive that is different from the first adhesive, and the second nozzle configured to apply the second adhesive to the substrate;
a third dispensing module having a third inlet and a third nozzle, the third inlet configured to receive the first adhesive, and the third nozzle configured to apply the first adhesive to the substrate;

a first pump having an inlet and an outlet, the first inlet of the first dispensing module configured to receive the first adhesive from the outlet of the first pump;
a second pump having an inlet and an outlet;
a manifold input that is configured to receive the first adhesive from a source of the first adhesive;
a supply channel that is in fluid communication with the manifold input, the inlet of the first pump, and the inlet of the second pump; and
a flow diverter plate that defines a body having a first surface in fluid communication with the first pump and the second pump, and a second surface opposite the first surface in fluid communication with the first dispensing module and the third dispensing module,
the third inlet of the third dispensing module being configured to receive the first adhesive from the outlet of the second pump,
the inlet of the first pump being in fluid communication with the manifold input to receive the first adhesive,
