Patent ID: 7967593

Claim:
An apparatus for supplying synthetic resins including a cutter wheel which rotates cutter units each having: a cutter for cutting a molten resin extruded from an extrusion opening of an extrusion nozzle of an extruder; and holding means for holding the molten resin cut by said cutter at a position close to said cutter, wherein said cutter wheel and a metal mold wheel are rotated in a manner that said holding means is positioned over a molten resin-receiving port of a mold at a portion where a rotary orbit of molds of a metal mold wheel for forming the molten resin is overlapped on a rotary orbit of said cutter units maintaining a gap in the up-and-down direction, and the molten resin held by said holding means is released at said overlapped portion so as to be supplied into the mold, said apparatus further comprising means for advancing and retreating said cutter units in a radial direction, and a change-over mechanism for controlling said means for advancing and retreating said cutter units to an expanded or contracted state, wherein the cutter units are moved by action of said change-over mechanism to an advanced position which is outward in the radial direction of rotation thereof when the molten resin is stably blown out from said extruder, the molten resin being cut by the cutters while said cutter units pass below the extrusion opening of the extrusion nozzle, and, when the molten resin is unstably blown out from said extruder, said cutter wheel continues to rotate while said cutter units retreat to retreated positions on an inner side in the radial direction of rotation thereof by action of said change-over mechanism so as not to come in contact with the molten resin.
