Abstract
Apparatus is disclosed for winding an elongate fibrous material 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, and variable speed drive means for rotating the package tubes. The variable speed drive means comprises a first output drive member for driving one of the package tubes, a second output drive member for driving the other of the package tubes, a constant speed input member, a drive transfer mechanism for transmitting drive from the input member to the output drive members throughout a predetermined range of complementary drive ratios and control means responsive to a predetermined control input progressively to adjust the drive transfer mechanism to vary the complementary drive ratios in such range to produce a gradual reduction in speed of one of the two output drive members with a corresponding increase in the speed of the other output drive member followed by a gradual reduction in speed of the other of the two output drive members with a corresponding increase in the speed of the one of the output drive members.
