Surface treatment machine

Abstract

A surface treatment machine comprising a chassis; a cutter member mounted to the chassis for milling a surface; and a smoother member mounted to the chassis for levelling raised edges of a milled surface, the smoother member positioned behind the cutter member relative to the direction of travel, wherein the smoother member comprises a movably supported impact element for impacting the raised edges of the milled surface.

What is claimed is: 
     
         1 . A surface treatment machine comprising:
 a chassis;   a cutter member mounted to the chassis for milling a surface; and   a smoother member mounted to the chassis for levelling raised edges of a milled surface, the smoother member positioned behind the cutter member relative to the direction of travel,   wherein the smoother member comprises a movably supported impact element for impacting the raised edges of the milled surface.   
     
     
         2 . The surface treatment machine of  claim 1  wherein the impact element is reciprocatable relative to the chassis and has a series of impact tools. 
     
     
         3 . The surface treatment machine of  claim 2  wherein the impact element is reciprocatable transverse to the direction of travel. 
     
     
         4 . The surface treatment machine of  claim 2  wherein the impact element is reciprocatable parallel to the direction of travel. 
     
     
         5 . The surface treatment machine of  claim 1  wherein the impact element is a rotatable relative to the chassis and has a series of laterally extending impact tools. 
     
     
         6 . The surface treatment machine of  claim 5  wherein the impact element is a chain. 
     
     
         7 . The surface treatment machine of  claim 5  wherein the impact element is a disk. 
     
     
         8 . The surface treatment machine of  claim 7  comprising at least three disks. 
     
     
         9 . The surface treatment machine of  claim 8  wherein the disks are mutually laterally spaced in a staggered arrangement. 
     
     
         10 . The surface treatment machine of any one of the preceding claims wherein smoother member is free floatingly mounted. 
     
     
         11 . The surface treatment machine of any one of  claims 1 - 9  wherein smoother member is provided with at least one surface engagement element. 
     
     
         12 . The surface treatment machine of any one of the preceding claims wherein smoother member is mounted to the chassis of the surface treatment machine. 
     
     
         13 . A method of manufacturing a surface treatment machine comprising the steps of:
 installing a cutter member to a chassis for milling a surface; and   installing a smoother member to the chassis for levelling raised edges of a milled surface, wherein the smoother member is positioned behind the cutter member relative to the direction of travel and comprises a movably supported impact element for impacting the raised edges of the milled surface.   
     
     
         14 . The method of  claim 13  comprising the step of arranging the impact element to reciprocate relative to the chassis. 
     
     
         15 . The method of  claim 13  comprising the step of arranging the impact element to rotate relative to the chassis.
