A winding device suitable for winding at least one strip on a mandrel. According to one embodiment the winding device includes a pressure assembly configured to press a strip against the surface of the mandrel when winding the strip. The pressure assembly comprises a first pressure unit which is coupled to and rotates together with the mandrel from a first winding position to a second winding position while the first pressure unit presses on the strip. The pressure assembly further comprises a second pressure unit that is attached to the first pressure unit, and that is configured for pressing on the strip when the first pressure unit reaches the second winding position, allowing forward movement of the strip in the winding direction when the mandrel rotates.
