Claim 17:
18. The cutting head device of claim 15, wherein said spool means comprising at least two cylindrical flanges where one of said flanges is radially extending from within a hollow cylindrical core and at least another of said flanges is extending from said hollow cylindrical core, wherein said flange extending from said hollow cylindrical core comprising a pair of blind flexible trimmer line guides, wherein each of said pair of blind flexible trimmer line guides is comprised of two flexible trimmer line guide sections including an external flexible trimmer line guide section crossing through said one flange radially extending from within said hollow cylindrical core and a semi-circular inner flexible trimmer line guide section disposed within said hollow cylindrical core, wherein said external flexible trimmer line guide sections are mirrored by a plane crossing through said spool means axis of rotation and extending from said hollow cylindrical core to the periphery of said one flange radially extending from within said hollow cylindrical core, and said semi-circular inner flexible trimmer line guide sections being each tangentially connected in unobstructed communication to each of said external flexible trimmer line guide sections and disposed within said hollow cylindrical core, wherein each of said external flexible trimmer line guide sections having an open window disposed within said one flange radially extending from within said hollow cylindrical core, and each of said semi-circular inner flexible trimmer line guide sections having a shallow floor below an open window disposed within said hollow cylindrical core and being covered by a thrust face of said coupling means for maintaining ends of a new flexible trimmer line constrained within each of said semi-circular inner flexible trimmer line guide sections by compressing said flexible trimmer line ends between said coupling means thrust face and said semi-circular inner flexible trimmer line guide sections shallow floor.
