Abstract
Abstract A solvent is sprayed onto a moving sander belt by a solvent nozzle moved across the belt in advance of an air nozzle, which blows air onto the belt. The nozzles are directed toward the belt at an angle such that the air from the air nozzle is deflected toward an exhaust port in a sander housing surrounding the belt. The nozzles form a part of a cleaner mounted as a unit on the sander housing, and including a nozzle carriage reciprocating the nozzles across the belt.

Total Claims: 12
Claim 1
Independent Claim
70 words
In a sander cleaner, a sanding element of a predetermined width and moved lengthwise along a predetermined path including a curved portion in which a sanding surface of the sanding element is convex, spray means for spraying a solvent at least partially tangentially onto the convex portion of the sanding surface of the sanding element, and means for moving the spray means to traverse the sanding element with the solvent.
Claim 2
Dependent Claim
70 words
In a sander cleaner, a sanding element of a predetermined width and moved lengthwise along a predetermined path including a curved portion in which a sanding surface of the sanding element is convex, spray means for spraying a solvent at least partially tangentially onto the convex portion of the sanding surface of the sanding element, and means for moving the spray means to traverse the sanding element with the solvent.
Claim 3
Dependent Claim
46 words
The sander cleaner of claim 1 wherein the spray means includes a solvent nozzle for applying a stream of solvent to the sanding element and an air nozzle for applying a stream of air at least partially tangentially to the convex portion of the sanding element.
Claim 4
Dependent Claim
108 words
In a sander cleaner, a sanding element of a predetermined width and moved lengthwise, spray means for spraying a solvent and air onto the sanding element, and means for moving the spray means to traverse the sanding element with the solvent and air, the spray means including a solvent nozzle for applying a stream of solvent to the sanding element and an air nozzle for applying a stream of air to the sanding element, the means for moving the spray means serving to move the solvent nozzle in advance of the air nozzle to apply the stream of air to a solvent wetted portion of the sanding element.
