Abstract
The invention also provides for an apparatus for feeding molten resin, wherein the apparatus includes holding units each having a respective holding portion that is opened and closed to hold a molten resin that is discharged from an extrusion port of a die head of an extruder and is cut by a cutter while moving on a track, in which, after the respective holding portion transfers the molten resin from the extrusion port to a female mold, a side of the respective holding portion is opened and the molten resin is fed down to the female mold in a compression-molding machine, wherein a plurality of longitudinal grooves extending up and down are formed in an inner circumferential surface of the respective holding portion that holds the molten resin.
