(54) Filament yarn take-up winder


(57) A plurality of packages are carried on a single bobbin holder, and package shape and yarn quality are made uniform. In a filament yarn take-up winder in which a plurality of packages Pa∼Pd are carried on a single bobbin holder, and in which a rotating contact roller 4 applies pressure to the packages while winding is performed, a contact roller 4 is comprised of 4 individually rotatable roller segments 4a∼4d, each arranged to correspond to one of the packages Pa∼Pd. When each roller segment 4a∼4d contains a driving DC brushless motor 10a∼10d, the tensions of the filament yarns Ya∼Yd being wound into packages Pa∼Pd, respectively, are individually detected by tension detecting mechanisms 11a∼11d. Each motor 10a∼10d is controlled based on the detected tension values.
