PURPOSE:To prevent glass fiber from being broken, while the length of a plunger in shortened by a method in which an inner barrel is provided freely slidably in an outer barrel, and the valve seat provided a little forward of the material inlet on the inner peripheral surface of the inner barrel is arranged to be capable of contact and remove from the valve body of the rotating plunger. CONSTITUTION:After the nozzle part 32 of an outer barrel 31 has been brought in contact with a stationary mold 35, while an inner barrel 33 is advanced and is positioned in an advance-limit, a plunger 46 is positioned so that a valve body 62 is a little apart from its valve seat 63, and then in rotating state, the resin material containing fiber is charged in a stuffer 55, and the material is pushed down by the plunger 57 of the stuffer. Said material is sent forward through the path 47 in the peripheral part of the plunger 46 being rotating and is accumulated successively in the inner barrel 33 and the outer barrel 31. In this measurement process, while the resin material in the periphery is uniformized by the rotation of the plunger 46, the breakage of the glass fiber contained in the material is also reduced, since the path 47 is short and the member such as a check ring is not present. |
