Abstract

PURPOSE: To form a metal-made blank pipe freely without impairing its properties and strength by forming the portion to become the end of the bat hitting part to protrusion form by rollers and cutting the same thereby joining and integrating these.
CONSTITUTION: The working for bending the end of the hitting part inward is accomplished by once removing the work and re-clamping the same with a chuck 3. This is accomplished as the work is guided by a gauge, wherein the ends 1', 1" of the blank pipe 1 are bent largely to the inner side by rollers R1, R2 and are aligned at the center A. Further, by strongly pressure-contacting these, the protrusion A' is formed and these are cut at the Y-Y' line and the end parts 1', 1" of the blank pipe are joined and integrated to themselves, wherby they are perfectly closed without leaving the trace of opening. Hence, the forming of the end part of the hitting part is readily and surely accomplished, thus the bat of the high integration strength may be obtained.
