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.
