PURPOSE: To make it possible to shorten a retention time of a molding material within a female mold in the state of no pressure by pressurizing independently from distance from material feeding apparatus to working station to start pressurizing operation and from speed of transfer. CONSTITUTION: When a female portion 12 is fed with molding material, a supporting member 13 retracts clockwise to the starting position. Caused by this rotation of the supporting member 13, tranion portion 21a of an eccentric shaft 21 engages with a guide groove 13a, from which the tranion 21a has disengaged. When the working station 2 starts transfer due to the next step motion of a rotor 1, a roller 25 fits sliding passage 26 for driving, causing rotation of eccentric shaft 21. In this manner, the support member 13 is transferred upward on a spline shaft 14. At this time, the female portion 12 located on the same axis as a mandrel 8 rises in accordance with rise of the support member 13 and performs pressurizing operation along with the mandrel. |
