Abstract

PURPOSE: To obtain a bent tube with beautiful end faces without having variation in the wall thickness by casting centrifugally a resin tube in a rubber mold one end of which is obliquely cut and which is placed in a rotating mold and placing in a bending mold the resin tube that was taken out with the rubber mold to form it bent.
CONSTITUTION: A rubber mold 4 one end of which is obliquely cut is placed in a rotating mold, and a resin tube is centrifugally formed on the rubber mold 4. Then the rubber mold 4 is taken out with the resin tube in it. Next, on the receiving section 23 of a curve forming mold 19 a jig 8 for the end face on the side of the receiving opening is set, and the rubber mold 4 and so on are set in the jig 8 with the sharp tip of the obliquely cut end at the top and the rubber mold 4 is deformed along the curved receiving mold 22, forming the resin tube curved along a curved receiving mold 22. In this arrangement the resin tube is curved, and a curved tube 24 is obtained.
