Abstract
Abstract An arrangement for mixing textile fiber in set quantity ratios, with at least two conveyers and at least two weighing feeders with scale tanks. Each conveyer has one weighing feeder with scale tank for delivering fiber flakes. Each conveyer has one conveyer roller and one breakup roller acting jointly for receiving the fiber flakes, and all conveyer rollers and breakup rollers are connected to a common flake suction device. Two horizontal endless conveyer belts may be used as conveyers. The rotary speed of the conveyers is continuously variable. The upper side of the conveyers runs towards the flake suction device. The conveyer rollers are located near belt rollers on the conveyers. Conveyer rollers and belt rollers have opposite directions of rotation, while breakup rollers and belt rollers rotate in the same direction. Air shield elements and the flake suction device may form an injector nozzle.
