ROLL HAVING LAMINATION STRUCTURE IN SHAFT DIRECTION COMPRISING CONNECTEDLY INSTALLED ASSEMBLED ELEMENT

摘要

PROBLEM TO BE SOLVED: To do away with existing concepts on a basic form of material elements constituting a roll body and provide a novel form and technical support based on an inherent background relating to up-to date functional rolls or the like, first of all general rolls. SOLUTION: This roll having a lamination structure in the shaft direction is constituted by preparing a partial component piece from a roll material, constituting an annular integrated element and an annular integrated element block 120 and cannulating the annular integrated element block 120 to a shaft body 2. Thus, utilization factors of elements can be improved and cost down of the product is realized. It is possible to popularize in wider uses. It responds to social needs by minimizing wasteful consumption of material sources.
