Abstract
Abstract A method and apparatus for cleaning abrasive belts of the type used in belt sanding operations. The apparatus includes a module having a frame composed of abradable side wall members. A block of cleaning material of natural or synthetic rubber is contained within the frame and engages the belt surface. The module is supported on a resilient base which is slightly compressible as the module passes through the belt sander to exert a uniform continuous biasing force on the belt surface to be cleaned as the module and belt are moved relative to one another.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
119 words
A method of cleaning clogging materials from the abrasive surface of a continuous abrasive belt machine having an adjacent spaced-apart conveyor with a work area defined between said belt and conveyor, said method comprising: (a) passing a cleaning module independent of said machine across the said work area so an area of the belt and module are moved relative one to the other, said module having a width substantially corresponding to the belt width and having a cleaning material contained within an abradable frame; (b) biasing said belt and module in contact one with the other as the module moves across the work area to cause said cleaning material to engage said belt and remove dust and pitch build-up.
Claim 2
Independent Claim
119 words
A method of cleaning clogging materials from the abrasive surface of a continuous abrasive belt machine having an adjacent spaced-apart conveyor with a work area defined between said belt and conveyor, said method comprising: (a) passing a cleaning module independent of said machine across the said work area so an area of the belt and module are moved relative one to the other, said module having a width substantially corresponding to the belt width and having a cleaning material contained within an abradable frame; (b) biasing said belt and module in contact one with the other as the module moves across the work area to cause said cleaning material to engage said belt and remove dust and pitch build-up.
Claim 3
Independent Claim
97 words
An apparatus for cleaning clogging materials from a moving abrasive belt surface of a sanding machine, said apparatus comprising: (a) a frame independent of said machine having side walls and a bottom and being comprised of an abradable material; (b) a cleaning material contained within said frame for causing removal of foreign material when engaged against the abrasive surface width; (c) resilient biasing means on the said bottom of said frame adapted to urge said cleaning material and said abrasive belt in substantial contact as the said frame and belt are moved relative one to the other.
Claim 4
Independent Claim
97 words
An apparatus for cleaning clogging materials from a moving abrasive belt surface of a sanding machine, said apparatus comprising: (a) a frame independent of said machine having side walls and a bottom and being comprised of an abradable material; (b) a cleaning material contained within said frame for causing removal of foreign material when engaged against the abrasive surface width; (c) resilient biasing means on the said bottom of said frame adapted to urge said cleaning material and said abrasive belt in substantial contact as the said frame and belt are moved relative one to the other.
Claim 5
Dependent Claim
17 words
The apparatus of claim 2 wherein said cleaning material comprises a block of natural plantation crepe rubber.
Claim 6
Dependent Claim
32 words
The apparatus of claim 2 wherein cleaning material is supported on a substantially rigid bottom extending within said frame and said resilient biasing means is secured to the underside of said bottom.
