摘要： A method of feeding a molten resin mass, which is capable of causing a molten resin mass to fall down into a female mold for compression molding without delay in the timing from a cylindrical transfer guide that cuts a portion of a molten resin extruded from a die head of an extruder and transfers it to a female mold for compression forming, and an apparatus therefor. The apparatus for feeding the molten resin mass has a cylindrical transfer guide which transfers a molten resin mass obtained by cutting a predetermined amount of a molten resin extruded from a die head of an extruder to a female mold for compression molding, wherein the transfer guide is provided with vibration-generating means for imparting vibration to the transfer guide. In the method of feeding the molten resin mass, the pressure in the cylindrical transfer guide is set to be higher than the pressure in the female mold for compression molding.
