  • Patent number: 6854811
    Abstract: A method for producing a brush, wherein a filament bundle strand is unwound from a spool and moved past a cutting device that severs a predetermined length of the strand for connection with the bristle carrier of the brush. In order to increase productivity, airflow is used to transport the unwound strand and the severed strand length. A pressure or vacuum source is provided which communicates with the take-off guide channel and/or the guide channel and which produces in the respective channel an airflow that is effective in the direction of transport of the strand.

  • Publication number: 20020180253
    Abstract: The present invention relates to a method and an apparatus for producing a brush. In accordance with said method, a strand of a single filament or of a bundle of filaments is unwound from a spool and moved past a cutting means in which a predetermined length piece of the strand is cut off. Subsequently, said length piece is connected to a bristle carrier. In order to increase the productivity, the present invention suggests that, when the strand or rather the length piece has been cut to length, it should be transported by means of an airflow. The risk that a filament kinks during transport of the strand can be excluded in this way. The apparatus according to the present invention comprises, in a manner known per se, at least one spool keeping a strand of a single filament or of a filament bundle ready for use.
