Trimmer head comprising at least two eyelets ( 17 ) and a bobbin ( 10 ) with at least two sections ( 11 , 12 ) for storing of one cutting filament ( 13 , 14 ) in each section, said eyelet ( 17 ) is placed in a housing surrounding the bobbin ( 10 ), characterized in that the eyelet ( 17 ) is provided with an opening ( 19 ) for the cutting filament, said opening ( 19 ) is extending in axial direction of the trimmer head so that the opening ( 19 ) provides access to all sections ( 11 , 12 ) for storing of cutting filaments ( 13 , 14 ) and that one side of the opening ( 19 ) has a groove shaped so that the cutting filament ( 13 , 14 ) is placed in the groove when the trimmer head rotates in the intended direction so that the cutting filament is placed in the groove by the forces generated by the rotation no matter of which section ( 11 , 12 ) of the bobbin ( 10 ) the filament ( 13 , 14 ) is stored in.

2 . Trimmer head according to claim 1 , characterized in that the eyelets ( 17 ) are placed around the same axial position on the trimmer head housing so that the cutting filaments ( 13 , 14 ) will rotate in the same plane around the trimmer head.

3 . Trimmer head according to claim 1 , characterized in that the different sections( 11 , 12 ) of the bobbin ( 10 ) is separated by at least fragments of a wall ( 14 ) extending in radial direction from a cylindrical section ( 16 ) in the centre of the bobbin ( 10 ).

4 . Trimmer head according to claim 3 , characterized in that the cylindrical section ( 16 ) is provided with a locking device that secures one end of the cutting filaments to the bobbin ( 10 ) in each of the different sections on the bobbin ( 10 ) for storing of one line of cutting filament in each section.

5 . Trimmer head according to claim 1 , characterized in that the number of eyelets ( 17 ) at least is the same as the number of cutting filaments in the trimmer head.

6 . Trimmer head according to claim 5 , characterized in that the trimmer head comprises two eyelets ( 17 ) and two cutting filaments ( 13 , 14 ).

7 . Trimmer head according to claim 1 , characterized in that the opening ( 19 ) in the eyelet ( 17 ) is V-shaped with a tip ( 20 ) in one end and a first ( 21 ) and a second end ( 22 ) separated from each other in the other end, said tip ( 20 ) of the V-shaped opening ( 19 ) is coinciding with the groove so that the cutting filament ( 13 , 14 ) is placed in the tip ( 20 ) when the trimmer head is rotating in the intended direction 8 . Trimmer head according to claim 7 , characterized in that the bobbin ( 10 ) comprises a first ( 11 ) and a second ( 12 ) section for storing of cutting filament.

9 . Trimmer head according to claim 8 , characterized in that the first ( 21 ) end of the opening ( 19 ) provides access to the first section ( 11 ) on the bobbin ( 10 ) and the second end ( 22 ) of the opening ( 19 ) to the second section ( 12 ) on the bobbin ( 10 ).

10 . Trimmer head according to claim 7 , characterized in that the V-shaped opening is rotated 90 in relation to the axial direction of the trimmer head, said tip ( 20 ) is pointing in the same direction as the cutting filament is extending in when it has entered the trimmer head housing through the eyelet ( 17 ).

11 . Trimmer head according to claim 1 , characterized in that the eyelet is made of a material that is resistant to wear.
