Industrial finishing files

Abstract

An industrial file is constructed by securing a non-woven abrasive impregnated fabric material to one or both sides of a structural support. The non-woven abrasive impregnated fabric material provides for an industrial file that may be used to contour, smooth and generally prepare a surface.

1 . An industrial file comprising:
 a structural support;   a non-woven abrasive impregnated fabric material on the structural support.   
     
     
         2 . The invention in accordance with  claim 1  wherein the structural support comprises a flat support having a first side and an obverse side and the non-woven abrasive impregnated fabric material is affixed to the first side of the structural support. 
     
     
         3 . The invention in accordance with  claim 2  comprising an abrasive material affixed to the obverse side of the structural support. 
     
     
         4 . The invention in accordance with  claim 3  wherein the abrasive material affixed to the obverse side of the structural support is a non-woven abrasive impregnated fabric material. 
     
     
         5 . The invention in accordance with  claim 1  wherein the structural support comprises a multisided structure. 
     
     
         6 . The invention in accordance with  claim 5  wherein the non-woven abrasive impregnated fabric material is fixedly attached to at least one surface of the multisided structural support. 
     
     
         7 . The invention in accordance with  claim 1  wherein the structural support comprises a structure having a non-rectangular cross-section transverse to the major axis of the industrial file. 
     
     
         8 . The invention in accordance with  claim 7  wherein the structural support comprises a structure having a circular cross-section transverse to the major axis of the industrial file. 
     
     
         9 . The invention in accordance with  claim 7  wherein the structural support comprises a structure having a triangular cross-section transverse to the major axis of the industrial file. 
     
     
         10 . An industrial finishing file comprising:
 a structural support having a first side and an obverse side;   an affixing layer in contact with the first side of the structural support and an affixing layer in contact with the obverse side of the structural support;   a non-woven abrasive impregnated fabric material in contact with the affixing layer on the first side of the structural support whereby the non-woven abrasive impregnated fabric material is affixedly coupled to the first side of the industrial file; and   an abrasive material in contact with the affixing layer on the obverse side of the structural support whereby the abrasive material is affixedly coupled to the obverse side of the industrial file.   
     
     
         11 . The industrial file of  claim 10  wherein the first abrasive material is a non-woven abrasive impregnated fabric material and the second abrasive material is a standard abrasive material. 
     
     
         12 . The invention in accordance with  claim 10  wherein the standard abrasive material is emery paper. 
     
     
         13 . The invention in accordance with  claim 10  wherein the standard abrasive material is sand paper. 
     
     
         14 . The invention in accordance with  claim 10  wherein the structural support is rectangular in shape. 
     
     
         15 . The invention in accordance with  claim 10  further comprising a handle portion of the structural support, the handle portion being free of abrasive material. 
     
     
         16 . The invention in accordance with  claim 16  further comprising:
 a tang portion extending from the structural support of the industrial file; 
 a handle portion being a removable handle that may be carried on the tang portion of the industrial file. 
 
     
     
         17 . The invention in accordance with  claim 16  wherein the removable handle comprises a tang receiving bore to receive the tang portion of the industrial file.
