ABSTRACT:
Apparatus for rounding the ends of brush fibers made of thermoplastic material includes a system for moving a smooth treatment surface relative to brush fiber ends at a relative speed and for a selected time to cause the brush fiber ends to be heated to their plastic deformation temperature to cause the brush fiber ends to become rounded. The treatment surface includes at least a portion which has substantially no abrasion, grinding or impacting properties relative to the brush fibers but only substantially friction heating properties relative to the fibers. A method for rounding brush fiber ends is described using the described apparatus.
