ABSTRACT:
Disclosed herein is an improved filament-type trimming apparatus comprising a casing having base and rim portions, a spool having a hub portion and opposite flanges, at least one filament wound on the spool and a cover adapted to support the spool within the casing. The spool is adapted to be moved radially inwardly and outwardly by reason of centrifugal force generated responsive to the speed of rotation of the casing. Upon such movement, when the spool rotates independently of the casing and the cover, additional filaments are automatically fed out. The feeding of additional filaments may be stopped when the spool is in engagement with either the casing or the cover.
