Abstract

PURPOSE:To prevent to produce defectives because of their mutual contact by a method wherein compressed air is blown out of the middle part of two articles which are molded by two parallel parisons at the same time and both of them are taken out into different directions. CONSTITUTION:Two parisons supplied in specified quantities are pinched between two parallel forming cavities 21, 21b of a blow mold, blow pins 30a, 30b are lowered from an upper portion of the mold and air is blown into the parisons, which are expanded in the form of cavities to obtain molded articles 10. Then, the mold is opened and the blow pins 30a, 30b are taken out of the molded articles 10. At the same time, compressed air is supplied to a blast nozzle 25 equipped at a hollow part 22 in a center of the mold and is blown from nozzles 26 to blow off the molded articles 10 into different directions.
