Abrasive Body

Abstract

It is disclosed an abrasive body having a work surface ( 2 ) that under operating conditions is designed to face a surface of an article of manufacture to be worked; this surface is provided with abrasive means to enable an abrading or finishing working; also present is a predetermined number of tongues ( 5 ) emerging from the central portion ( 4 ) of the abrasive body ( 1 ) to enable engagement of the latter with a support ( 6 ). The abrasive body is made of an elastically deformable material and is not fastened to the lower surface ( 8 ) of the support ( 6 ). The presence of cuts ( 9 ) on the tongues ( 5 ) increases gripping of the abrasive body on the support and use of the elastic material gives the abrasive body a longer duration and greater yield and allows better finishing off while reducing clogging problems.

       14 . An abrasive body comprising:
 a work surface ( 2 ) that is designed, under working conditions, to face a surface to be worked;   abrasive means ( 3 ) associated at least with one central portion ( 4 ) of the abrasive body ( 1 ) to enable said working by abrasion; and   a predetermined number of tongues ( 5 ) emerging from the central portion ( 4 ) of the abrasive body ( 1 ) to enable engagement of the abrasive body itself with a support ( 6 ), wherein said abrasive body ( 1 ) is at least partly made of an elastically deformable material.   
   
   
       15 . An abrasive body as claimed in  claim 14 , wherein under engagement conditions of the tongues ( 5 ) with the support ( 6 ) an upper surface ( 7 ) of the abrasive body ( 1 ) is not directly fastened to the lower surface ( 8 ) of the support ( 6 ). 
   
   
       16 . An abrasive body as claimed in  claim 14 , wherein at least one of the tongues ( 5 ) have a cut ( 9 ) defined by edges adjacent to each other ( 10 ,  11 ) said cut ( 9 ) being set to enable engagement of the tongue ( 5 ) with a respective pin ( 12 ) emerging from the upper surface ( 13 ) of the support ( 6 ). 
   
   
       17 . An abrasive body as claimed in  claim 14 , wherein the central portion ( 4 ) of the abrasive body ( 1 ) and the tongues ( 5 ) are of one piece construction and are made of an elastically extendible material. 
   
   
       18 . An abrasive body as claimed in  claim 14 , wherein the central portion ( 4 ) and tongues ( 5 ) are made separately and fastened to each other by suitable connecting means. 
   
   
       19 . An abrasive body as claimed in  claim 14 , wherein the abrasive means ( 3 ) is directly in engagement at least with the central portion ( 4 ) of the abrasive body ( 1 ) at the work surface ( 2 ) without interposition of any surface of non elastic material such as paper material. 
   
   
       20 . An abrasive body as claimed in  claim 14 , wherein the abrasive means ( 3 ) is dispersed within at least the central portion ( 4 ) of the abrasive body ( 1 ). 
   
   
       21 . An abrasive body as claimed in  claim 14 , wherein the abrasive body is made of an elastically extendible material and is impervious to the passage of the abraded powder. 
   
   
       22 . An abrasive body as claimed in  claim 14 , wherein the abrasive body is made of an elastically extendible material, said abrasive body ( 1 ) enabling passage of the abraded powder through its central portion ( 4 ) at least when it is elastically deformed. 
   
   
       23 . An abrasive body as claimed in  claim 14 , wherein the central portion ( 4 ) is flat and is fully formed of an elastic material enabling at least deformation of same in the extension plane thereof. 
   
   
       24 . An abrasive body as claimed in  claim 14 , wherein the central portion ( 4 ) has a plurality of through holes ( 14 ) to enable possible suction of the abraded particles. 
   
   
       25 . An abrasive body as claimed in  claim 14 , wherein at least the tongues ( 5 ) are made of an elastically deformable material to enable engagement with the support ( 6 ). 
   
   
       26 . An abrasive body as claimed in  claim 16 , wherein under engagement conditions of the tongues ( 5 ) with the pins ( 12 ) of the support, one of the adjacent edges ( 11 ) is in the form of a tab pressing against the pin itself. 
   
   
       27 . An abrasive body comprising:
 a work surface ( 2 ) that is designed, under working conditions, to face a surface to be worked;   abrasive means ( 3 ) associated at least with one central portion ( 4 ) of the abrasive body ( 1 ) to enable said working by abrasion; and   a predetermined number of tongues ( 5 ) emerging from the central portion ( 4 ) of the abrasive body ( 1 ) to enable engagement of the abrasive body itself with a support ( 6 ), wherein said abrasive body ( 1 ) is at least partly made of an elastically deformable material and the abrasive body ( 1 ) is connectable to a supporting wheel ( 6 ) exclusively by means of said tongues ( 5 ), the central portion ( 4 ) being not linked to and movable due to its elasticity with respect to a lower surface of the supporting wheel ( 6 ).   
   
   
       28 . An abrasive body comprising:
 a work surface ( 2 ) that is designed, under working conditions, to face a surface to be worked;   abrasive means ( 3 ) associated at least with one central portion ( 4 ) of the abrasive body ( 1 ) to enable said working by abrasion; and   a predetermined number of tongues ( 5 ) emerging from the central portion ( 4 ) of the abrasive body ( 1 ) to enable engagement of the abrasive body itself with a support ( 6 ), wherein said abrasive body ( 1 ) is at least partly made of an elastically deformable material and the abrasive means ( 3 ) is dispersed in a thickness of the abrasive body ( 1 ) at least in the central portion ( 4 ).
