Abstract
A trimmer head for a rotary line trimmer including a housing operatively connected to the trimmer and a spool for carrying cutting line thereon. The spool is operatively connected to the housing for rotation therewith and defines a line receptor channel having opposed open ends and traversing the spool. The channel is formed by line guide inserts held within the spool body preferably utilizing the shrinkage of the molded spool material about the inserts. The channel can be aligned with the eyelets in the housing skirt such that cutting line can be inserted therethrough and wrapped about the spool upon relative rotation of the spool and housing without having to interrupt the operative connection therebetween. A central portion of the channel is exposed to provide access to the line so that the line can be pulled from the head without having to interrupt the operative connection therebetween.
