ABSTRACT:
In a filament type trimmer in which a filament is wound on a storage spool rotatably mounted in a rotating housing having a rim portion, the filament in passing from the spool to an exit opening in the rim portion of the housing extends through a flexible tubular guide which wraps approximately one turn around the spool. The guide prevents the outer coils on the spool from becoming entangled and also prevents local melting and welding of the outer coils as the result of axial vibration in the string during operation of the trimmer.
