Abstract
PURPOSE: To facilitate the rolling work through lapping and bonding a metallic sheet and splitting the same into a cylindrical unit body and to improve the pro- ductivity, by providing V-shaped notches at both ends of a cutting line for splitting formed at the intermediate part in the direction of the width of a metallic sheet and cutting off each corner of it.
CONSTITUTION: Four right angle corners 29aW29d of a metallic sheet 23 are obliquely cut off and V-shaped notches 30a, 30b are also provided at both ends 24, 25 on a cutting line 28 for splitting formed at the intermediate part in the direction of the width of a metallic sheet 23. Then, the notches 30a, 30b are lapped over each other to form a notch hole 31 and it is bonded to obtain a cylindrical body 21. Furthermore, it is cut along the cutting line 28 for splitting so as to form a cylindrical unit body 36. Accordingly, a notch 37 quite similar to a notch 34 prepared around the circumferential edge part 32 of the cylindrical body 21 is constituted. Therefore, the lapping part around the circumferential edge part of a metallic plate of the unit body 36 can be removed to easily execute the rolling work.
