For intermediate storage, printed products are often wound onto winding cores mounted on roll supports (3) with a horizontal winding axis. After intermediate storage the printed products are unwound again. For winding-up and un-winding, a roll support (3) is positioned in a winding station and when winding-up or un-winding is complete the roll support (3) is replaced by another one. In order to serve an arrangement of winding stations (W) and storage positions (L) for roll supports (3) efficiently and possibly in a fully automated manner on as little space as possible and with an orientation of winding stations (W) and storage positions (L) substantially freely adaptable to given conditions, a manipulator (1) is used for manipulation and transport of the roll supports (3). This manipulator is movable in x-, y-, and z- directions and rotatable around a vertical rotation axis. It comprises at least two coupling means (2) arranged around the vertical rotation axis with an angle of 90° between them. The manipulator-coupling-means (2) can each be coupled to a coupling means (2') arranged on the rear narrow side of each roll support (3). For an exchange of roll supports, the manipulator (1), to which a roll support (3) is coupled, is moved to the winding station (W) such that the roll support (3) to be replaced can be coupled to the second coupling means (2) of the manipulator. Then the roll support (3) is removed from the winding station (W), the manipulator (1) is rotated by 90° in order to orient the other roll support to the winding station (W), the other roll support (3) is introduced into the winding station (W) and is de-coupled. Then the manipulator (1) is withdrawn together with the removed roll support.
