Abstract: A roll sorter device has a first roll that can be driven rotatably about its roll axis and a second roll that can be driven rotatably about its roll axis opposite the rotation of the first roll. The second roll is arranged spaced from the first roll such that the roll axes of the first and second rolls are arranged substantially parallel to each other. The roll sorter device may include a detection device for detecting seized and/or faulty preforms on the first or second roll and a roll arrangement modification element to modify the arrangement of the first and second rolls to each other when the detection device detects seized preforms. A sorting method for sorting performs and a transport device may employ the aforementioned roll sorter device.
