Abstract
An unwinding device for wound rolls includes a bearing element, a first support element and a second support element mounted on the bearing element. The first and second support elements are adapted to rotatably hold the wound roll on opposed sides. The first support element and the second support element are movable along the bearing element with respect to one another, such that a distance between the first support element and the second support element changes. The unwinding device also includes a drive mechanism adapted to move the first support element and the second support element along the bearing element. The drive mechanism includes a tensioner movable along the bearing element, and a first engagement member disposed on the first support element. The first engagement member is adapted to releasably lock the first support element to the tensioner.
