Abstract (en)

[origin: EP2937303A1] A winding drum (73) of a winding device (7) provided to a fine spinning machine (1) is adapted to rotate in contact with a package (80) to frictionally drive the package (80). The winding drum (73) includes a plurality of high-frictional portions (76). The plurality of high-frictional portions (76) is provided with a frictional surface (77) adapted to form a portion of an outer peripheral surface of the winding drum (73). A surface shape and a material of the frictional surface (77) differ from a drum main body (75). The high-frictional portion (76) is arranged to make contact with an inner portion of the package (80) located inward with respect to an end of the package (80).
