Floor treatment device and method for manufacturing same

Abstract

A floor treatment device includes a pad ( 1 ) of an open lofty non-woven material as well as a plurality of segments ( 3 ) spaced from one another and consisting of a plastic material ( 4 ) and abrasive particles ( 7, 8 ), such as diamond particles. The segments are adhered to a surface ( 2 ) of the pad ( 1 ). The floor treatment device is characterized by bodies ( 5 ) which are embedded in the plastic material ( 4 ) of the segments ( 3 ), the bodies ( 5 ) including a matrix material ( 6 ) as well as abrasive particles ( 7 ) contained in the matrix material.

         5 . Floor treatment device according to  claim 1 , wherein the size of the bodies ( 5 ) is at least an order of magnitude smaller than the size of the segments ( 3 ). 
     
     
         6 . Floor treatment device according to  claim 1 , wherein the size of the bodies ( 5 ) is 1-5 mm. 
     
     
         7 . Floor treatment device according to  claim 1 , wherein a number of 10-100 bodies ( 5 ) is contained in a segment ( 3 ). 
     
     
         8 . Floor treatment device according to  claim 1 , wherein the bodies ( 5 ) comprise a resin matrix material. 
     
     
         9 . Floor treatment device according to  claim 1 , wherein the segments ( 3 ) contain abrasive particles ( 8 ) outside the area thereof which is occupied by the bodies ( 5 ). 
     
     
         10 . Floor treatment device according to  claim 1 , wherein the segments ( 3 ) comprise a resin material. 
     
     
         11 . Process for manufacturing a floor treatment device according to  claim 1 , comprising the steps of:
 providing a pad of an open lofty non-woven material,   providing a flowable plastic material,   providing bodies comprising a matrix material as well as abrasive particles contained in said matrix material,   pouring the flowable plastic material on the pad while allowing the flowable plastic material to penetrate into the voids of the open lofty non-woven material of the pad,   applying the bodies on and/or in the still flowable plastic material,   curing the flowable plastic material.   
     
     
         12 . Process according to  claim 11 , comprising the steps of:
 providing a mixture of a flowable plastic material containing bodies comprising a matrix material as well as abrasive particles contained in said matrix material,   pouring the mixture on the pad while allowing the flowable plastic material to penetrate into the voids of the open lofty non-woven material of the pad,   curing the flowable plastic material.   
     
     
         13 . Process according to  claim 11 , comprising the step of pouring the mixture onto a surface of the pad according to multiple members while maintaining free surface parts between the members. 
     
     
         14 . Process according to  claim 11 , comprising the steps of:
 providing a plastic material containing a harder,   curing the plastic material under the influence of the harder.   
     
     
         15 . Floor treatment device according to  claim 2 , wherein the bodies ( 5 ) are spread throughout the plastic material ( 4 ) of the segments ( 5 ). 
     
     
         16 . Process according to  claim 12 , comprising the step of pouring the mixture onto a surface of the pad according to multiple members while maintaining free surface parts between the members.
