Abstract

The brush manufacturing machine of the type wherein at least one rotary brush body carrying drum located at a machine workstation is cyclically supplied with empty brush bodies by a brush body feeding device and is cyclically rotated to cause each such brush body to be eventually presented in proper position before a filling tool for filling of the brush body with brush fibers, wherein the machine includes at least two drums located at sequential workstations, at least one filling tool at each workstation cooperating with each respective drum for delivering brush fibers to the brush bodies carried by the drums, at least one manipulator operable so as to periodically engage and transfer brush bodies from at least one drum to another drum following the one drum, and a transport device for carrying filled brush bodies away from a drum of the machine. The invention also resides in a method of making brush bodies including the steps of locating a series of brush body carrying drums having working side areas arranged to support and hold brush bodies at sequential workstations and periodically supplying the side areas of the first drum of the series with unfilled brush bodies by a brush body supply device located in advance of the first drum; locating a filling tool at each workstation, the filling tool being arranged to insert brush fibers into at least some of the brush bodies carried by a respective drum at the workstation; transferring the brush bodies between the drums of the series, including transferring unfilled brush bodies to at least one of the drums of the series directly from another one of the drums of the series located at a workstation preceding the drum to which the unfilled brush bodies are transferred. Several embodiments of the invention are described.
