Abstract: The invention relates to a winding device (1) for winding up and unwinding goods (2) in web form, in particular a conveyor belt, whereby the wound goods (3) are supported on a substructure (4). The substructure has at least two support rollers (5, 6), which are disposed at a distance (A1, A2, A3) from one another, whereby the support rollers are adjustable, changing the distance, in order to adapt themselves to any winding diameter (D1, D2), whereby the movement sequence of the support rollers takes place in such a manner that the wound goods are furthermore securely supported. It is practical if the winding device (1) is provided with lateral supports (7), which have a wheel that is adjustable in height, which is set to the center (M1, M2) of the wound goods (3). Lateral migration is prevented in this manner, for the purpose of optimizing a secured position.
