Device and a method for transferring advancing yarn during bobbin changeover in an automatic turret type yarn winder

A device (1) for transferring advancing yarn during bobbin changeover in an automatic turret type yarn winder incorporating a winder frame (1A), a rotatable turret (8) on which a plurality of rotatable spindles for holding bobbins (4 and 9) are mounted, means for rotating said turret (8) to alternate exchange positions of said bobbins (4 and 9) between a winding position and a stand-by position, and a traverse housing (13) characterized in that said yarn transfer device (1) comprises a traverse device (2) for traversing at least one advancing yarn (3) into the yarn traverse area (6) of the winding bobbin (9) and an actuation device (5) capable of generating axial forward and reverse movements of said traverse device (2) internally inside said traverse housing (13), during yarn transfer in bobbin changeover operation, wherein said actuation device (5) is positioned inside said traverse housing (13);

• wherein said traverse device (2) comprises a rotatable cross-spiral shaft (11) mounted inside a cam box (10), said cam box (10) enclosed within said traverse housing (13), a traverse guide (7) engaged with said cross-spiral shaft (11), a drive means (12) for imparting rotational motion to said cross-spiral shaft (11), said drive means (12) axially positioned with respect to and directly connected with said cross-spiral shaft (11), and wherein said traverse guide (7) traverses continuously at its normal traversing speed without coming to a complete halt during the yarn transfer or bobbin changeover operation.
