作加工が簡易で、しかもロールを形成する部材の結合が
強固で欠陥のないロールの創出が望まれていた。However, the above-mentioned conventional rolls have the following problems. Rolls in which the roller and the shaft are integrally formed by drawing are difficult to produce when the difference between the outer diameters of the roller and the shaft is large, or when the entire length of the roll is long. For this reason, there is a problem that it is not suitable for production of a small amount or production of many kinds. On the other hand, in a roll formed by forming the roller and the shaft separately, and then integrally joining the shaft to the end face of the roller by the friction welding method, it is difficult to set various conditions of the friction welding. There is a problem that it is difficult to use different kinds of materials for the roller portion and the shaft portion because the materials are restricted. In addition, there is a problem that the processing cannot be performed until after the joining, and the positioning of the roller portion and the shaft portion at the time of joining is unstable, so that the subsequent working is troublesome. In particular, when the difference in the outer diameter between the roller portion and the shaft portion is large, or when the length of the entire roll is long, the post-processing becomes extremely difficult. Furthermore, when the outer diameter of the roller portion is cut in the post-processing, a pinhole or the like is generated at the joint portion, and the surface becomes rough.
These pinholes cannot be determined until after the cutting process, and are fatal defects for the rolls. Therefore, the production process is simple, and the bonding of the members that form the rolls is strong, and a roll with no defects is created. Was desired.

1) is press-fitted to the fitting portion (21) of the roller portion (2). At the time of fitting, the end of the roller portion (2) projects outward from the large diameter portion of the shaft portion (3) as shown in FIG. Next, the two parts are integrally fixed to the fitting parts of the two parts by fillet welding from the inside of the protruding part (indicated by an arrow A in FIG. 1). In the case where the joint surface between the roller portion (2) and the shaft portion (3) is flush, it is necessary to make a groove in the joint portion at the time of welding in order to obtain joint strength, which is troublesome, and the joint portion is difficult. Since it is located on the end face of the roller, the strength of the joint decreases when cutting the end face.
If the end of the roller portion (2) is made to protrude from the shaft portion (3) and the both are joined by fillet welding, sufficient joining strength can be obtained without taking a groove, and the end surface is cut in post-processing. Even in the case of processing, there is no possibility that the strength is reduced because the joining portion is not exposed on the end face of the roller portion. Further, cutting of the outer diameter of the roller portion can be performed without any adverse effect, and does not affect the quality of the roll (1). In addition, as a welding means, means such as fusion welding, for example, arc welding, electron beam welding and the like are preferable, but not particularly limited.
