An improved rotary melt cutter apparatus for producing pellets from at least one strand of a partly molten thermosplastic resin in cooperation with a die, said die having a die surface with at least one orifice, said improved rotary melt cutter apparatus adapted to be driven rotationally by a rotating shaft structure, said apparatus comprising rotating knife assembly and means connecting said assembly to said rotating shaft structure, said rotating knife assembly comprising a drive rod connected to said shaft structure, a knife holder and attached thereto an approximately center-supported knife, said drive rod cooperating with said knife assembly connecting means such that said drive rod has limited free rotation about its axis running to said rotating shaft structure, said knife holder being connected to said drive rod, said knife holder being axially aligned with and connected to said drive rod such that said knife holder has limited axial free rotation, said rotating knife assembly mounted and supported in cooperative association with said die surface and said orifice of said die such that the plane of rotation of said knife assembly about the axis of said rotating shaft structure is maintained adjacent and in alignment substantially parallel to said die surface and said orifice such that only a limited amount of wear of both the knife and the die occurs during operation, and means for advancing said rotating knife assembly toward said die surface and said extrusion orifice.
