A device for drawing-off endless screw elements (2) rotationally fixed on a bearing shaft (1) has at least one drawing-off ring (7, 8) that surrounds at least one endless screw element (2) to be drawn off. The drawing-off ring (7, 8) has an inner thread (9) with a pitch which corresponds to the pitch of the endless screw element (2) it surrounds. The endless screw element (2) engages with its web (5) the inner thread (9) of the drawing-off ring (7, 8) in such a way that the flanks (11, 12) of the thread of the drawing-off ring lie on the flanks (13, 14) of the web of the endless screw element (2). |
