Abstract
A method of building a filled roll in the form of a load-carrying shaft and a stack of annular fillings sleeved upon the shaft and an end head sleeved upon the shaft at each opposite end of the stack, includes the steps: concentrating compressive forces on the end heads and the stack therebetween in the axial direction of the shaft and on axially aligned concentric loci defined on the outboard faces of the end heads and radially spaced from and circumadjacent the shaft periphery for precluding end head deformation under the applied compressive forces, the surface area of each end face inboard of the respective locus being equal to the surface area outboard thereof as figured from the area of the fillings of the stack, and with the inner end face of each end head having a negative taper at the interface of the end head and the respective end of the stack.
