PURPOSE: To prevent works from being set in a multicavity processing part in an unordinary state by a method wherein a lock part is engaged with the reverse insertion tip part of a work and formed in such a shape to block relative movement of a guide plate through coordination with the work. CONSTITUTION: A lock part 4 is arranged at a feed device for an inert material 3 and when insertion is effected with the reverse insertion tip part 3a of the insert material 3 in an unordinary state situated in front, the reverse insertion tip part 3a is engaged with a groove 4b formed in the lock part 4, whereby a guide plate 10 is immovable in a moving direction. Thus, since, with the insert material 3 being in an unordinary state, a regulation hole 11 and a guide hole 2 are not positioned facing each other, unordinary insertion of the insert material 3 is prevented from occurring and all molded products are prevented from being a defective product. The insert material 3 in an unordinary state is also prevented from damaging a molding cavity. |
