Abstract

A flaring apparatus including at least one of die member positional adjustment apparatus and a defective rim element ejecting apparatus. The positional adjustment apparatus includes a connecting shaft provided between a die member mounting block and a link mechanism for moving the mounting block. The connecting shaft has shaft portions, axes of which are radially offset from each other. By rotating the connecting shaft, the die member position can be adjusted. Therefore, there is no need to provide a shim between the die member and the mounting block. The defective rim element ejecting apparatus includes a pressure sensing switch which can detect an increase in pressure within a space defined by a rim element and the die members during flaring. When the pressure sensing switch does not detect a predetermined increase in the pressure of the space, for example, when the rim is cracked, a conveyor path device opens and the defective rim element will drop into an ejecting duct thereby ejecting the defective rim element from the manufacturing line.
