  • Hot strip coiling mandrel
    Patent number: 4107969
    Abstract: A hot strip coiling mandrel has a mechanism for engaging a plurality of equally circumferentially divided drum segments about a core shaft and for moving the core shaft or the drum segments relatively axially to thereby radially expand and collapse the drum defined by the segments. Top marks caused at the leading coil end of a hot strip by the use of such a mandrel are prevented by the provision of a buffer between the core shaft and each of the drum segments.
