Abstract

PURPOSE: To compactly make the sleeve having plural uneven part on the inner face by inserting the core forming a recessed part or projecting part on the outer periphery into the sleeve and compressing the sleeve outer periphery by a roll by driving a wedge in the gap part of the core.
CONSTITUTION: The split core 1 having plural projecting or recessed part grooves 2 on the outer periphery and of which core part is of a truncated conical shape is inserted into a sleeve 7. A wedge 4 is driven into the center gap part 3 of the split core 1 to compress the sleeve 7 outer periphery by a roll. Thereafter, the core 1 is taken off by pulling the wedge 4 out to form plural projecting or recessed parts on the sleeve 7 inner face. The sleeve for reinforced joint with uneven part on the inner face is thus made compactly and at low cost.
