Abstract
A spray device and a method of using the spray device are provided. The spray device facilitates the application of a liquid such as a pretreatment liquid to an area of a fabric material. The spray device can be positioned on or adjacent portions of the fabric material and/or a substrate supporting the fabric material. The spray device can be activated to spray the pretreatment liquid and move the spray device on portions of the fabric material and/or the substrate supporting the fabric material.
Claims20
A portable spray device for spraying pretreatment liquid to an area of a fabric shirt, the portable spray device comprising:
- a housing portion having a leading end, a trailing end, a first lateral side, and a second lateral side,
- a first wheel positioned at the first lateral side of the housing portion, and having a first axis of rotation,
- a second wheel positioned at the second lateral side of the housing portion, and having a second axis of rotation,
- at least a third wheel positioned at the leading end of the housing portion, and having a third axis of rotation,
- at least one motor attached to the housing portion for rotating the first wheel and the second wheel,
- a sprayer attached to the housing portion at the trailing end thereof, and being configured to spray the pretreatment liquid therefrom, and
- a controller configured to activate the at least one motor to rotate the first wheel and the second wheel, and configured to activate the sprayer to spray the pretreatment liquid therefrom,
- wherein, when the first wheel, the second wheel, and the third wheel are positioned on a portion of the fabric shirt, the controller is configured to activate rotation of the first wheel and the second wheel to move the portable spray device from a first position on the fabric shirt to a second position on the fabric shirt, and to simultaneously operate the sprayer to spray the pretreatment liquid in a spray area on the fabric shirt during movement of the portable spray device from the first position to the second position, and
- when the first wheel, the second wheel, and the third wheel are contacted to the fabric shirt, a first plane perpendicular to the first axis of rotation passes through the first wheel and the spray area, a second plane perpendicular to the second axis of rotation passes through the second wheel and the spray area, and a third plane perpendicular to the third axis of rotation passes through the third wheel, through the spray area, and is positioned between the first plane and the second plane.
