ABSTRACT:
Thin walled pipes, as for example pressure gauge springs are bent by inserting a flexible mandrel in to the pipe and to forward the pipe simultaneously with the mandrel over a forming member until a sufficient length of the pipe is provided for the bending step. The mandrel is then forwarded relative to the pipe to project therefrom and both parts are bent around the forming member. Then, the mandrel is retracted and the pipe arc is separated.
