Abstract

PURPOSE: To provide bellows improved in the strength against the external pressure by providing a female mold forming a flat part at a part of a corrugated part, thinning a split mold in the vicinity of the female mold and making the waveform pitch in the periphery of the flat part small.
CONSTITUTION: Split molds 3aW3i parallelly provided between end plates 2 and 2 are mutually separated, and each of split molds is divided into two parts to open the upper part of the main body 1 of the metal mold. Then, a tube 11 is accommodated in the metal mold mainbody 1, and both ends of the tube are bonded to the inner surfaces of the end plates 2 and 2, and thereafter the split molds 3aW3i are blocked. In this state, air is supplied in the tube 11 through an air supply port 12, and the end plates 2 and 2 are pressed in the arrow direction. The interval of the split molds 3aW3i is narrowed and bonded together. A female mold 7 is accommodated in the escaping parts 8 and 8 of the split molds 3d and 3f. As a result, bellows 13 having a flat part 13b at a part of the corrugated part 13a are formed, and a narrow corrugated part 13c is molded.
