Abstract
A device for winding and unwinding a web of material and including two separated uprights, in each of which is mounted a horizontal chuck onto which the core tube can be introduced. To prevent the core tube from corrugating or tearing, there is a mechanism (15-17) that supports the reel (8) at the bottom during winding and unwinding and that can move along with the reel.
