Method and device for manufacturing brushes

A device for manufacturing brushes comprising:

• a boring tool;
• a filling tool;
• at least three brush body holders;
• and means for manipulating the brush body holders such that during a work cycle, two of said at least three brush body holders present two brush bodies to the boring tool and the filling tool respectively, whereas another brush body holder of the above-mentioned three brush body holders alternately carries off a filled brush body and supplies an empty brush body and the at least three brush body holders are automatically taken to a following work station according to a closed circuit at the end of each work cycle.

A method of manufacturing brushes comprising:

• providing a boring tool;
• providing a filling tool;
• providing first, second and third movable supports for supporting and shifting brush bodies between various workstations including a first workstation defined at said boring tool whereat the brush bodies are bored to produce various openings and a second workstation defined at said filling tool whereat the produced openings are filled with brush elements;
• supplying a first brush body to said first movable support;
• transferring said first brush body to said first workstation by shifting said first movable support;
• forming various openings in said first brush body with said boring tool;
• supplying a second brush body from said third movable support to said first movable support;
• transferring the first brush body from said first workstation to said second movable support;
• transferring the second brush body from said first movable support to said first workstation while transferring the first brush body from said second movable support to said second workstation;
• forming various openings in said second brush body with said boring tool at the first workstation while inserting numerous brush elements into the first brush body with said filling tool at said second workstation;
• supplying a third brush body to said first movable support by means of said third movable support;
• transferring said second brush body from said first workstation to said second movable support while transferring said first brush body from said second workstation to said third movable support;
• delivering said first brush body to a completed brush zone by said third movable support while transferring said second brush body from said second movable support to said second workstation and transferring the third brush body from said first movable support to said first workstation.
