A sealing arrangement (14,28) for sealing overlapped panels (18) of a carton (16) folded onto a mandrel (14) includes a pressure sealing assembly (48,52,54,56) and a drive member (36). An elastomeric disc (62) is retained compressed between the drive member (36) and the pressure sealing assembly (48,52,54,56). A drive unit serves to extend the drive member (36), thereby to urge a pressure pad (56) of the pressure sealing assembly (48,52,54,56) via the elastomeric disc (62) into pressure-sealing engagement with the overlapped panels (18) on the mandrel (14). <IMAGE> |
