Roof adhesive distribution apparatus
View Patent ↗A distribution apparatus for applying a one or two-part adhesive to a substrate includes a wand with a plurality of openings through which the adhesive is dispensed. An extension is connected in fluid communication to the wand. The extension directs a flow of adhesive to the wand.
1. A distribution apparatus for applying a one or two-part adhesive to a substrate, the distribution apparatus comprising:
a wand with a plurality of openings through which the adhesive is dispensed, the wand further comprising at least one perimeter channel and a set of cross channel holes, wherein each cross channel hole is aligned with at least one of the plurality of openings; and
an extension connected in fluid communication to the wand, wherein the extension directs a flow of adhesive to the wand.
2. The distribution apparatus of claim 1 wherein each of the plurality of openings is circular.
3. The distribution apparatus of claim 1 wherein one or more of the plurality of openings is non-circular.
4. The distribution apparatus of claim 1 wherein the plurality of openings are equally spaced.
5. The distribution apparatus of claim 1 wherein the spacing between the openings of the plurality of openings is varied.
6. The distribution apparatus of claim 1 wherein the wand is a straight bar.
7. The distribution apparatus of claim 1 wherein the extension is a static mixer that mixes a first part and a second part of a two-part adhesive.
8. The distribution apparatus of claim 1 wherein the extension is connected to a static mixer that receives a first part and a second part of a two-part adhesive, mixes the first part and the second part of the two-part adhesive, and directs the two-part adhesive to the extension.
9. The distribution apparatus of claim 1 wherein the wand has a first end and a second end, a distance from the first end to where the extension is connected to the wand being less than a distance from the second end to where the extension is connected.
10. The distribution apparatus of claim 1 further comprising a first wheel attached to a first end of the wand and a second wheel attached to a second end of the wand.
11. The distribution apparatus of claim 10 wherein the wheels space the wand a uniform distance from the substrate.
12. The distribution apparatus of claim 1 further comprising a quick-release snap connection that connects the extension to the wand.
13. A distribution apparatus for applying a two-part adhesive to a substrate, the distribution apparatus comprising:
a cart with a frame that supports a first collapsible bag that contains a first part of the two part adhesive, a second collapsible bag that contains a second part of the two part adhesive, a first pump in fluid communication with the first collapsible bag, and a second pump in fluid communication with the second collapsible bag;
an extension in fluid communication with the first pump and the second pump, the first pump and the second pump drawing the first part and the second part of the two-part adhesive, respectively, and directing the first part and the second part of the two-part adhesive to the extension, the extension mixing the first part and the second part of the two-part adhesive to form the two-part adhesive; and
a wand with a plurality of openings, the wand receiving the two-part adhesive and dispensing the two-part adhesive through the plurality of openings onto the substrate.
14. The distribution apparatus of claim 13 wherein each of the plurality openings is circular.
15. The distribution apparatus of claim 14 wherein the plurality of openings are equally spaced.
16. The distribution apparatus of claim 13 wherein the extension is a static mixer that mixes a first part and a second part of a two-part adhesive.
17. The distribution apparatus of claim 13 wherein the wand has a first end and a second end, a distance from the first end to where the extension is connected to the wand being less than a distance from the second end to where the extension is connected.
18. The distribution apparatus of claim 13 further comprising a first wheel attached to a first end of the wand and a second wheel attached to a second end of the wand.
19. The distribution apparatus of claim 18 wherein the wheels space the wand a uniform distance from the substrate.
20. The distribution apparatus of claim 13 wherein the cart includes a gear box that drives the first pump and the second pump.
21. The distribution apparatus of claim 20 wherein the gear box has two or more speeds to drive the pumps at two or more flow rates.
