Abstract

PURPOSE: To obtain the angle duct made from synthetic resin which is excellent in flexibility and elasticity by molding a soft synthetic-resin hose provided with hard synthetic-resin thread through attachment or embedment and by softening the same by heating to form its cross section into the polygonal.
CONSTITUTION: On the outer-peripheral surface of a hose wall 1 formed by winding spirally a tape made from soft vinyl chloride and further by bonding the side edges thereof to each other is attached a reinforcing thread 2 made from hard vinyl chloride spirally, whereby a hose H is formed. Next, after the hose H is softened by heating the same approximately to the temperature of thermal deformation thereof, the hose is expanded only in the vertical direction by a forming tool, a jack for instance, inserted into the hose. Then the hose H having a round cross section is transformed into the angle duct D having a rectangular cross section with the reinforcing thread 2 made from hard synthetic resin being attached on the outer- peripheral surface of the main body 3 thereof made from soft synthetic resin.
