The invention relates to a device for making a cut in the peripheral direction of a plastic seal, comprising at least one blade, said blade being held by a holding device, and a fixing device for the seal. The invention is characterised in that the holding device (11) can be moved in relation to a path of motion (7) of the seal (3) by means of a control mechanism (29), in that the seal (3) is arranged in such a way that it can turn around its middle axis (5), and in that the cut is made by turning the seal (3) around its middle axis (5), the distance between the seal (3) and the blade (15) remaining constant or essentially constant whilst the seal is being turned. |
