Abstract (en)

[origin: EP2210848A1] The drive drum (12) has a drum hub with a support unit contact surface surrounding a drum axis of rotation. A radial distance of the support-unit contact surface from the drum axis of rotation increases in a partial area of the support unit contact surface as the angle of rotation increases. A belt-like support unit (14) is driven and wound in the drive drum.
