Abstract: Line-winding spool for grass-cutting heads, comprising a central body provided with a central axis of rotation coinciding with the axis of rotation of the grass-cutting head when inserted into it, said central body having a circumferential side area on which there is defined the annular area where the cutting line is wound, said spool having at least one channel crossing said central body transversally, provided with two openings on opposite portions of said side area for the insertion of the cutting line, said at least one channel having two opposite first segments starting from said openings towards the inside of the central body, and a curved connection segment between said first segments having a concave shape with the concavity upwards, said central body defining, in said concavity, a cavity, whose bottom is at a lower axial height than the axial height of said openings, characterized in that said curved connection segment has a lower surface that is substantially continuous along all its extension so as

Abstract: 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).
