Abstract (en)
[origin: EP3572364A1] A winding unit (4) comprising a bobbin (8) wound about a corresponding hollow tube (12), a yarn clearer (20) adapted to verify the presence of defects in the yarn (16) unwound from the bobbin (8), a reel (24) onto which the yarn (16) unwound from the bobbin (8) is wound, a cutting device (28) to cut the yarn (16) when identifying yarn defects (16) to be eliminated, an anti-curl device (32) placed close to the bobbin (8) and adapted to prevent the yarn (16) on the bobbin side (8) from curling and/or twisting following the cutting or the yarn (16) from breaking. The anti-curl device (32) advantageously comprises an arm (36) positioned close to an upper end (40) of the bobbin (8), on the side where the yarn (16) is unwound from the bobbin (8). Said arm (36) is provided with at least one outlet nozzle (52) connected to a compressed air source so as to direct a flow of compressed air close to the upper end (40) of the bobbin (8), thus facilitating the entry of the yarn (16) into said hollow tube (12).
