Abstract

PURPOSE: To obtain a tapered pipe of a uniform shape by a method wherein an intake pipe is produced from a circular cross-sectional pipe, then it is machined to form a tapered nozzle on its internal surface while maintaining it in the circular cross-sectional pipe shape as a whole, and it is formed to be a rectangular-section pipe.
CONSTITUTION: The intake pipe 2 is produced from a circular cross-sectional pipe, and while maintaining the pipe in the circular cross-section as a whole, it is subjected to turning to form the tapered nozzle. Then, the pipe is formed to be a rectangular cross-sectional pipe, for example, by a plastic working in which a mandrel having a rectangular cross-sectional shape is placed inside the pipe and the pipe is pressed against the mandrel. The pipe thus shaped is jointed to the tip part of a scoop pipe 1. Accordingly, the nozzle having four sides tapered uniformly is obtained, and the shape of the tapered nozzle is made to be uniform throughout all of the product.
