    摘要： A line(F)-type trimmer head (1) is described, configured to rotate around a rotation axis (A-A) and comprising a housing (3) composed of at least one first housing portion (5) and one second housing portion (7), which can be torsionally and axially coupled to one another and which form a volume for a stock of cutting line (F). The second housing portion comprises at least one first passage (31), transverse with respect to the rotation axis of the trimmer head, with a first end and a second end configured and arranged so as to be positioned in correspondence of the two exit holes (9) for the cutting line, so that a cutting line can be inserted through one exit hole and extracted from the other exit hole, passing along the first transverse passage.

    摘要： The grass-cutting head (1) with cutting line (F) includes an outer housing (3) and a spool (5) housed in the outer housing. The spool includes an axial cavity (9) and two opposite channels (17) for insertion of the cutting line (F). A spring (11), elastically biases the spool with respect to the housing, and two bushings (7) are approximately diametrically opposite in a lateral wall of the outer housing (3), which are alignable with openings of the two opposite cutting line insertion channels. In the axial cavity (9) of the spool (5) there are formed two opposite projections (21) for supporting the spring (11), forming pairs of lead-in and guide surfaces (21A) converging toward respective openings (17B) of the two opposite cutting line insertion channels, facing the axial cavity (9) of the spool (5).
