Document Type and Number:
Japanese Patent JPH11138227
Kind Code:
A
Abstract:
To provide the manufacturing method for the new cylindrical laminated body which is advantageous to improve a productivity.
A stepped base cylinder 4 is formed, on which plural cylindrical parts 41, 42 and 43 whose diameters become small by stages as they proceed to one end in the axial length direction, are arranged in series through stepped parts 46, 47. By applying a compressive force to the stepped base cylinder 4 along the axial length direction of the stepped base cylinder 4, the stepped parts 46, 47 are ruptured, and the plural cylindrical parts 41, 42 and 43 are laid over the other, and the cylindrical laminated body 7 is formed.
