Abstract
An apparatus for transporting a printing material sheet includes a holding crossmember for holding the printing material sheet and a traveling-wave motor for driving the holding crossmember. The traveling-wave motor has a first traveler and a second traveler for mounting the holding crossmember. The holding crossmember is mounted through a spring suspension. The spring suspension can be, for example, a flexible joint in the form of a flexible bellows.
