  • Coil support for a trimmer line coil
    Patent number: 9550651
    Abstract: A coil support with a coil of a trimmer line has a coil core with an outer wall surface and first and second axial ends. At the axial ends securing elements that project past the wall surface of the coil core are provided for positional fixation of the coil wound onto the coil core. A securing element provided at the first axial end is a support plate with a longitudinal center axis. The size of the support plate is provided in the direction of the longitudinal center axis with a greater extension than transverse to the longitudinal center axis such that the support plate in a first radial direction of the coil core is greater than in a second radial direction. The coil core is fixedly connected with the support plate and with the further securing elements that are provided on the second axial end.
