Abstract:
1. An apparatus for feeding molten resin, the apparatus including 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 said 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 said molten resin, wherein said plurality of grooves are structured and arranged to discharge oligomers formed in gaps located between the molten resin and said plurality of grooves via either an upper end or a lower end of said plurality of grooves, wherein said plurality of grooves are configured to prevent adhesion of said oligomers formed in the gaps so as to allow the molten resin to fall out into the female mold.
