Abstract
A lower mold half is horizontally placed. The top surface of the lower mold half is provided with a first groove of any desired shape, one end of which is closed with the other end having a notch for allowing air to be blown in. An upper mold half has a bottom surface which matches the top surface of the lower mold half and which is provided with a second groove corresponding in shape to said first groove. Thus, when the upper and lower mold halves are brought into contact, there is formed a mold cavity defined by the first and second grooves. A discharging unit including a nozzle for discharging a parison is disposed above the lower mold half and the nozzle is so provided that it can rotate in either direction at a variable speed. At least one of the nozzle and the lower mold half is movably provided to lay a parison in the first groove.
