0019]With an advantageous transport device of this type, it is possible to position the holding unit initially at a narrow end of the object or component to be rolled up, and to then grip or hold the component or object. In particular, the suction elements located inside the contour of the object are activated. Next, e.g., the holding unit or the cylindrical roll-up gripper may be advantageously displaced or moved in the longitudinal direction of the object, preferably synchronously with its roll-up motion or rotational motion. As a result, the object is rolled up on the holding unit or the roll-up gripper without undergoing stress or deformation.
