METHOD OF HOT-BENDING TUBES OR PIPES OF PLASTICS MATERIAL AND A PRODUCT PRODUCED THEREBY

摘要

Method for bending tubes of plastic material, for the construction of furniture and the like, characterized in that it consists of filling the required section of tube with material resistant to grains of high thermal capacity such as shot or spheres of cast iron, steel or the like, in sealing the ends of the tube section thus filled, in heating the assembly in a furnace to just below the softening temperature of the material of which the tube is composed, in arranging the tube thus heated in a mold with a channel that reproduces the curvature or the desired drawing, in rapidly cooling the tube thus curved and in emptying it of the shot or the like previously arranged inside it.
