Abstract
A final finish-rolling stand of a rolling machine for producing round bar material is constructed as an eight-roller type rolling machine comprising: front four rollers of "+" distribution and back four rollers of "X" distribution which are contained in one housing block. Only one driving source is used for the rolling machine, and the driving force from the driving source is transmitted to one roller of the front four rollers to forcibly drive this roller. The remaining rollers are freely rotatable and rotate synchronously with transfer of the material being rolled so as to carry out rolling down of the material. Structure of the rolling machine is simple and adjustable range of sizes of the product is wide.
