Retractor device

A spreading device (1) for multiple material sheet strips (4) cut from a material sheet (5) by a material sheet cutting device, wherein the material sheet strips (4) are fed to the spreading device (1) along a transport path in a feed plane (6) and leave the spreading device (1) in a discharge plane (7) in order to be subsequently transported, offset parallel to one another, to a winding shaft arrangement and to be wound onto a common winding shaft, wherein the spreading device (1) comprises two deflection elements (2 and 3), which each extend transversely to the transport path and are configured and arranged such that a strip spacing (9) between two material sheet strips (4) guided adjacent to one another along a transport path in succession over the first and second deflection elements (2 and 3) is greater in the discharge plane (7) than in the feed plane (6), wherein the deflection elements (2 and 3) are arranged to be non-rotatable, and in that each deflection element (2 and 3) comprises a number of openings (15) in a transport contact area (13) of a deflection sheath surface (12) of the deflection elements (2 and 3) covered by the material sheet strips (4) transported thereover, through which compressed air can be blown in order to create a friction-reducing air layer between the material sheet strips (4) and the deflection sheath surfaces (12) of the deflection elements (2 and 3) in the transport contact area (13), wherein:

• the two deflection elements (2, 3) are arranged and configured such that the feed plane (6) and the discharge plane (7) are offset parallel to each other, and
• the deflection elements (2, 3) are configured such that the material sheet strips (4) are transported between the two deflection elements (2, 3) at least approximately at a right angle relative to the feed plane (6) and the discharge plane (7).
