Abstract:
A method of endrounding fibers of thermoplastic material for use in brush making, the fibers being presented to an endrounding tool in a tuft and the free ends of the fibers being exposed to a working surface of the tool, the fibers being held in an axial direction of the tuft with their free ends commonly defining a surface different from a plane which is perpendicular to the axial direction and being permitted to flex laterally while they are exposed to the working surface of the tool, said tuft of fibers exceeding the amount of fibers needed for a brush to be made being picked from a supply of packed pre-cut fiber, the relative movement between the ends of the fibers of the tuft and the working surface of the tool causing the material of the fibers to be heated by friction of a predetermined intensity, and said fibers being deposited in a container containing endrounded fiber.
