发明名称 CROSSHEAD
摘要 The objective of the present invention is to form a pair of sheets by bisecting a parison, using a first branching body of a separator provided on the lower portion of a core or a die, and a second branching body provided on the die or the core. This crosshead is configured so that first branching bodies (33) of separators (5, 5a) provided on a core (9) or a die (8) are brought into contact with second branching bodies (40) provided on the core (9) or the die (8), and thereby a parison (3) drooping from a resin flow path (30) between the core (9) and the die (8) is bisected and a pair of sheets (7) is formed.
