Device for manufacturing brushes and method applied thereby

Abstract

Device for manufacturing brushes, more particularly for inserting fibers in a brush body, which device mainly consists of a filling tool and at least one supply duct, characterized in that between the supply duct ( 3 ) and the filling tool ( 7 ) is provided at least one rounding means ( 16 ).

1 .- In a device for manufacturing brushes, a device for inserting fibers in a brush body, said device comprising a filling tool and at least one fiber supply duct, wherein between the supply duct and the filling tool at least one rounding device is provided.  
   
   
       2 .- The device according to  claim 1 , comprising several supply ducts which are each provided with a rounding means.  
   
   
       3 .- The device according to  claim 1 , wherein the at least one rounding device is located opposite a bundle remover which comprises a bundle remover housing with at least one opening in which has been provided a rotatable body which moves within the opening in a close-fitting manner, said rotatable body including grooves in an outer edge for picking up fibers.  
   
   
       4 .- The device according to  claim 3 , including multiple openings in the bundle remover housing, wherein a first one of said openings is located opposite a distal end of said at least one supply duct.  
   
   
       5 .- The device according to  claim 3 , including multiple bundle removers, and wherein between the different bundle removers and the filling tool is provided a distributing device with at least one cartridge provided with at least one recess.  
   
   
       6 .- The device according to  claim 5 , wherein the distributing device comprises a distributing device housing which forms a whole with the bundle remover housing, wherein in the distributing device housing and the bundle remover housing, opposite each of the bundle removers, there is provided a second opening.  
   
   
       7 .- The device according to  claim 6 , wherein opposite each of the second openings in the distributing device housing and the bundle remover housing there is provided a guide having an edge which is oriented in slanting relationship relative to the direction of movement of the rotatable body of the respective bundle remover.  
   
   
       8 .- A method for manufacturing brushes, comprising: supplying fibers in at least one supply duct; presenting the fibers in the supply duct to a filling tool which inserts the fibers in a brush body; and presenting the fibers from said at least one supply duct to a rounding device, before presenting them to the filling tool.  
   
   
       9 .- The method according to  claim 8 , including loading the fibers of each supply duct into grooves of a rotating cylindrical body, and by moving the body such that a respective groove is presented to a respective supply duct the fibers are pushed into a respective groove by a press-on device which pushes the fibers into the groove.  
   
   
       10 .- The method according to  claim 9 , wherein the fibers which are loaded in a respective groove are presented to the rounding device by rotating the cylindrical body.  
   
   
       11 .- The method according to  claim 9 , wherein the fibers are loaded out of each of the respective grooves into recesses which are provided in cartridges of a distributing device.  
   
   
       12 .- The method according to  claim 11 , wherein the fibers are removed out the respective groove by means of a guide which is provided with a slanting edge in order to move the fibers out of the respective groove into one of the recesses in a cartridge of the distributing device.
