Abstract
An opener device in an open-end spinning machine includes an opener roller driven by a drive disk and a drive belt. A tension roller is movable between a first position wherein it exerts a driving tension force on the drive belt, and a second position wherein the tension roller exerts a lesser tension on the drive belt so that the drive belt can be removed from the device. A braking device includes a movable actuating element and a braking belt contacting member, such as a bolt, associated with the actuating element so as to be moved thereby. The actuating element and braking belt contacting member are movable between a first position wherein the braking belt contacting member is at a distance from the drive belt and a second position wherein the braking belt contacting member comes into the contact with the drive belt forcing the belt away from the drive disk.
