METHOD OF PRODUCING METALLIC ENDLESS BELT FOR BELT MACHINE, ENDLESS BELT, AND BELT MACHINE HAVING THE ENDLESS BELT MOUNTED THEREON

摘要

PROBLEM TO BE SOLVED: To provide a stainless steel endless belt which is particularly applicable to a belt machine, wherein the endless belt has a required fracture strength and a difference in sheet thickness between a welded joint portion and a belt base material is minimized to a value extremely close to zero, and to provide a method of effectively producing the endless belt.;SOLUTION: There are provided the method and an apparatus for producing the stainless steel endless belts (101, 102) which are applicable to the belt machine (100), wherein the endless belts (101, 102) are wrapped on a plurality of drums (103, 104) to be rotated, whereby various processes are continuously carried out on their traveling surfaces. According to the method, a stainless steel belt material is obtained by cold rolling, and its ends are welded to each other to produce the endless belt. Then the entire surfaces of the welded endless belt (101 or 102) inclusive of the belt base material (101a or 102a) and the welded portion (101b or 102b) are ground and smoothed. At this time, both the entire front and rear surfaces of the welded endless belt (101 or 102) inclusive of the belt base material (101a or 102a) and the welded portion (101b or 102b) are ground surface by surface, until a difference in sheet thickness between the welded portion (101b or 102b) and the belt base material (101a or 102a) is reduced to 50 m or less.;COPYRIGHT: (C)2005,JPO&NCIPI
