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.

Abstract: Disclosed is a drag lever (1) comprising two side walls (2, 3) which are connected together by a transversal bar (4) which is arranged on an end (6) of the lower side (5) thereof on an end (6) thereof on a head of a support element (9) by means of a dome-shaped cavity (7) on a head (8) of a support element (9). A clamp (10) is applied to the end (6) thereof. The clamp fixes the drag lever (1) to the head such that it can be displaced in a pivoting direction thereof. The clamp (10) is made of thin-walled wire material and extends essentially in a transversal manner in relation to the longitudinal axis of the drag lever (1) and is arranged on the lower side (5) of the transversal bar (4) by means of a central section (11) which is formed by webs (12, 13) which extended in a semi-circular manner in a part of the support element (9) which has a reduced diameter (14) and is located below said head (8).
