Claim:
A trimmer head for use with at least one length of flexible cutting line in a flexible line rotary trimmer, said head comprising: a housing adapted to be operatively connected to a rotary trimmer to effect rotation of said head, said housing defining a cylindrical depending skirt having at least one line outlet opening therein; a spool operatively connected to said housing for rotation therewith about a common axis in a drive mode and for rotation with respect to said housing in a line winding mode, said spool including a cylindrical body portion and at least one flange projecting radially therefrom so as to define a cutting line storage area about said body portion adjacent to said flange, the operative connection between said spool and said housing effecting reciprocal movement between said spool and said housing along said common axis of rotation upon rotation of said spool with respect to said housing in the line winding mode; and at least one line receptor formed in said flange, said receptor including an inwardly extending channel, said channel defining an outer end alignable with said line outlet opening in said skirt upon relative rotation of said spool and said housing and wherein at least an outer portion of said channel is polygonal in cross-section for gripping a length of cutting line upon an end portion of the line being inserted into said channel through said line outlet opening, a portion of the line extending from said channel being directed toward said body portion of said spool as said spool is rotated with respect to said housing.
