Abstract

An apparatus for masking an article with masking material is disclosed. The apparatus generally includes a spray head connected to a primary channel which forms a passage for the masking material. This channel has two sections, the first of which terminates in a junction with the spray head and is angled from the second section. In addition, the apparatus has at least one secondary channel which forms an air passage and is attached to the primary angled channel.

First claim

The invention claimed is:

1. An apparatus for masking an article with a masking material comprising:
a spray head in communication with a primary channel forming a passage for said masking material, said primary channel having a first portion, which terminates in the spray head, and a second portion providing an entire remainder of said primary channel, the first portion angled from the second portion, wherein the second portion is longer than the first portion, and wherein a ratio of a length of the second portion to a length of the first portion is substantially equal to two to one, wherein the primary channel is provided by a single, continuous structure; and
at least one secondary channel, forming an air passage, and attached to the first portion of the primary channel.

2. The apparatus as in claim 1 , wherein an angle between the first portion and the second portion is within the range of 35° to 145° when measured from the longitudinal axis of the second portion to the center of the first portion.

3. The apparatus as in claim 2 , wherein an angle between the first portion and the second portion is approximately 45°.

4. The apparatus as in claim 1 , wherein the at least one secondary channel is configured such that a jet of air expelled from the at least one secondary channel would atomize masking material expelled from the primary channel.

5. The apparatus as in claim 1 , wherein the masking material is an ultraviolet (UV) curable material.

6. The apparatus as in claim 1 , wherein rotation and translation of the primary channel results in corresponding rotation and translation of the secondary channel.

7. A system for masking an article with a masking material comprising:
a spray head in communication with a primary channel forming a passage for said masking material, said primary channel having a first portion, which terminates in the spray head, and a second portion providing an entire remainder of said primary channel, the first portion angled from the second portion, wherein the second portion is longer than the first portion, and wherein a ratio of a length of the second portion to a length of the first portion is substantially equal to two to one, wherein the primary channel is provided by a single, continuous structure;
at least one secondary channel, forming an air passage, and attached to the first portion of the primary channel; and
at least one actuator capable of propelling masking material through the primary channel and capable of passing air through the at least one secondary channel.

8. The system of claim 7 , wherein the at least one actuator is capable of propelling masking material through the primary channel while concurrently passing air through the at least on secondary channel.

9. The system of claim 8 , wherein the at least one actuator is a single actuator in communication with a supply of masking material and an air tank.

10. The system as in claim 7 , wherein the angle between the first portion and the second portion is within the range of 35° to 145° when measured from the longitudinal axis of the second portion to the center of the first portion.

11. The system of claim 7 , wherein the at least one secondary channel is configured such that a jet of air expelled from the at least one secondary channel atomizes the masking material expelled from the primary channel.

12. The system as in claim 7 , wherein rotation and translation of the primary channel results in corresponding rotation and translation of the secondary channel.

13. The system as in claim 7 , wherein the masking material is an ultraviolet (UV) curable material.
