PURPOSE: Spiral synthetic resin products, and a method and an apparatus for fabricating the same are provided to improve appearance of construction materials or accessories by forming colored waterdrop patterns in the spiral synthetic resin products. CONSTITUTION: A spiral synthetic resin products are made of transparent synthetic resin. Each side of the spiral synthetic resin products is formed with convex lenses. A colored line is inserted into the center of each side of the spiral synthetic resin products. Each protruding part of the spiral synthetic resin products forms a convex lens together with the colored line, thereby forming waterdrop patterns. An apparatus for fabricating the spiral synthetic resin products include an extruder(10), a seizing(20) for preventing the products from being deformed, a cooler(30), a withdrawing roller(40) for withdrawing hardened products, and a winding machine(50) for winding the products.
