For inserting and removing packers into and from a rolling mill stand having roll adjusting hydraulic piston and cylinder assemblies in the top of each stand housing, a packer-carrying sledge runs on tracks extending into the stand below the lowermost rolls of the stand. The sledge is located in the stand during rolling and can carry packers which are located operatively between the chocks of the lowermost roll and the housings.
