Abstract
Apparatus is disclosed for winding an elongate fibrous material, such as a sliver or roving, comprising: package tube mounting means to support first and second package tubes in winding positions in transversely spaced parallel relationship; a material delivery arm for delivering material first to one of the package tubes to form a first package and then to the other of the package tubes to form a second package; drive means for rotating the package tubes for winding on material; the delivery arm being arranged during the building of a package to contact the package at a winding-on point which lies in a plane containing the axes of rotation of the two package tubes and to deliver material at the winding-on point direct to the package under a winding tension localized in the region of the winding-on point by the delivery arm; first traversing means for causing relative traversing movement between each package tube and the delivery arm in the direction of the axis of rotation of the tube for building a parallel-build package on the tube and second traversing means operative during the building of each package to cause in a direction perpendicular to the axis of rotation of the tubes a relative displacement between the delivery arm and the package tube to accommodate the increasing diameter of the package being built on the tube and to maintain the winding-on point in the plane containing the axes of rotation.
