Abstract

See full text

Bristles are fed to a brush-making machine by an apparatus having a drum centered on and extending along a drum axis and formed with a plurality of angularly spaced and axially extending passages each of a circularly segmental cross section with a vertex directed radially inward toward the axis and each having a downstream end and an opposite upstream end. A respective group of elongated flexible bristles is supplied through the upstream ends into each of the passages and expelled from the downstream ends. A nozzle immediately downstream of the downstream ends has an outlet aperture of a predetermined inside diameter and a frustoconical inner surface tapering downstream away from the downstream ends and axially aligned with the downstream passage ends such that at least some of the bristles exiting the downstream end of each passage engage and are deflected by the inner surface.
