Head for brush cutters

A head for a brush cutter (1), intended to comprise a cutting wire and having an operating rotation (R) around an axis (A) by means of a driving torque (C) supplied by an external rotating shaft, comprising:

• an outer casing (3), which is substantially cylindrical, internally hollow, extending around said axis (A) and comprising at least a first through eyelet (4a) and a second through eyelet (4b), arranged preferably diametrically opposite said axis (A) by means of which a first end portion and a second end portion of said wire emerge from said head (1),
• a spool (6) extending around said axis (A) and rotationally coupled or couplable by a coupling mechanism inside said outer casing (3) and configured to be decoupled rotationally from said outer casing (3) by means of a decoupling mechanism that is actuatable by an actuating device permitting partial unwinding of said wire, said spool (6) comprising:
• a base body (7) which is substantially cylindrical;
• at least one annular housing (8) arranged perimetrically around said base body (7) and around which said wire is wound or windable;
• at least a first opening (9a) and a second opening (9b) that are arranged in positions substantially diametrically opposite each other and connected by means of at least one internal channel (10) intended for the insertion of said wire;
• wherein said head (1) provides for reloading the wire, wherein said wire is insertable inside said head (1) from the outside by means of said first or second eyelet (4a or 4b), when said first and second eyelets (4a and 4b) face respectively said first and second openings (9a, 9b), said reloading involving a relative rotation (X) of said spool (6) that is discordant relative to said outer casing (3);
• and said head (1) comprising:
• a reloading device coupled with the spool (6) and configured to rotate the spool (6) relatively to the outer casing (3) around the axis (A) to reload said wire on the spool (6);
• an interface device configured to show, outside the head (1), at least one indicator (20) identifying a relative angular position of said spool (6);
• at least one reference (23) arranged on the external surface of the outer casing (3);
• and
• wherein said at least one indicator (20) and said at least one reference (23) are suitable for defining at least one logic and/or position correspondence that is detectable by a user to identify each first and second eyelets (4a or 4b) respectively facing each of said first and second openings (9a, 9b).
