Broom and method of fabrication thereof

Abstract

A bristled tool head and a method of fabrication thereof, the method comprising molding a shell having a top surface and a bottom surface, the bottom surface comprising a pattern of housings, the housings being selectively localised and inclined relative to a direction normal to a plan of the shell depending on a position along a length and across a width of the bottom surface; finishing the housings of the as-molded shell into sockets; and securing tufts of bristles within the sockets.

1 . A method of fabrication of a bristled tool head, comprising:
 molding a shell having a top surface and a bottom surface, the bottom surface comprising a pattern of housings, the housings being selectively localised and inclined relative to a direction normal to a plan of the shell depending on a position along a length and across a width of the bottom surface;   finishing the housings of the as-molded shell into sockets; and   securing tufts of bristles within the sockets.   
     
     
         2 . The method of  claim 1 , wherein a longitudinal axis of each housing has an angle relative to the direction normal to the plan of the shell selected depending on a respective position of each housing along the length and across the width of the bottom surface. 
     
     
         3 . The method of  claim 1 , comprising selecting a depth of each housing relative to a height of the shell. 
     
     
         4 . The method of  claim 1 , wherein said step of finishing the housings comprises drilling each of the housings to a shape selected depending on the respective position of each housing along the length and across the width of the bottom surface. 
     
     
         5 . The method of  claim 1 , wherein said step of finishing the housings comprises positioning the as-molded shell in a tufting machine, the bottom surface of the as-molded shell facing a tufting head of the tufting machine. 
     
     
         6 . The method of  claim 1 , wherein said step of finishing the housings comprises positioning the as-molded shell in a tufting machine, the bottom surface of the as-molded shell facing a tufting head of the tufting machine; and drilling of the housings in a first pass of the tufting head into sockets of a shape depending on the position along the length and across the width of the bottom surface. 
     
     
         7 . The method of  claim 1 , wherein said step of finishing the housings comprises positioning the as-molded shell in a tufting machine, the bottom surface of the as-molded shell facing a tufting head of the tufting machine; and drilling of the housings in a first pass of the tufting head into sockets of a shape depending on the position along the length and across the width of the bottom surface; and said step of securing tufts of bristles within the sockets comprises positioning bristles within the sockets in a following pass of the tufting head. 
     
     
         8 . The method of  claim 1 , wherein said step of securing tufts of bristles within the sockets comprises selecting, of the as-molded shell, at least one of: i) a material of the bristles; ii) a density of the bristles; iii) a number of the bristles; iv) a diameter of the bristles; and v) a length of the bristles. 
     
     
         9 . The method of  claim 1 , wherein said step of securing tufts of bristles within the sockets comprises clamping tufts of bristles to a bottom of the sockets. 
     
     
         10 . The method of  claim 1 , wherein said step of finishing the housings of the as-molded shell into sockets comprises selecting a shape of each socket depending on the position along the length and across the width of the bottom surface. 
     
     
         11 . A method of fabrication of an angled-bristled tool head, comprising molding a shell comprising a pattern of housings selectively localised and inclined relative to a direction normal to a plan of the shell; finishing the housings of the as-molded shell into sockets; and tufting bristles within the sockets. 
     
     
         12 . The method of  claim 11 , wherein the pattern of housings is selectively localised and inclined relative to a direction normal to the plan of the shell depending on a position along a length and across a width of the bottom surface. 
     
     
         13 . The method of  claim 11 , wherein said steps of finishing the housings of the as-molded shell into sockets and of tufting bristles within the sockets are performed using a same tufting machine. 
     
     
         14 . A one-piece molded bristled tool head, comprising a top surface and a bottom surface, wherein said bottom surface comprises a pattern of sockets selectively localised and inclined relative to a direction normal to a plan of the tool head depending on a position along a length and across a width of the bottom surface, and tufts of bristles secured within said sockets.
