Abstract

PURPOSE: To prevent the dispersion of strength, by uniformalizing the construction of edge portion blanks by bending the edge portion blanks cut down along the longitudinal directions of rolling materials so that the longitudinal directions be changed in the circumferential directions in surfaces containing the surfaces of the blanks.
CONSTITUTION: Edge portions 1, 1' are mounted on an outer circumference of a drum portion 2, both portions 1, 1' and the portion 2 are joined at welding portions 3, 3', and the edge portions are cut, thus forming a saw edge with a fixed shape. Here, materials with excellent high toughness and wear proof are used for edge nose portions 1a, and cheap, general metal for structure is employed for edge root portions 1b. The edge portions 1, 1' are made up is such a manner that a several sheet of edge portion blanks cut down along the longitudinal directions of rolling materials with width B and thickness T are stacked, and the blanks are bent by means of an ordinary bending roll, etc. so that they be built up bending radii R and in order that the longitudinal directions of the edge portion blanks be turned in the circumferential directions in surfaces containing the surfaces of the edge portion blanks. Thus, the saw edge that is difficult to be damaged can be acquired because the dispersion of the strength of the edge portions 1, 1' is eliminated.
