A mass of mutually stuck noodles is unbound by unbinding rods. Within a housing 11 is arranged a rotating shaft 12 to extend horizontally, and a plurality of unbinding rods 13 are secured to the rotating shaft 12 at diagonally opposed positions to extend in radial directions like tow combs, said unbinding rods 13 being curved and having a given length. Within the housing 11, an inner wall surface 14 is arranged along a circular arc whose center is aligned with an axis of the rotating shaft 12 and whose diameter is slightly larger than a diameter of a circle drawn by rotating tips 13a of the unbinding rods 13. A portion of the inner wall surface 14 extending from a horizontal level h passing through the center of the rotating shaft 12 to a lower end of an inlet 15 is formed as an unbinding surface 17 having a circular arc cross sectional shape facing the unbinding rods with a small clearance. A mass of noodles N for one meal charged into the housing 11 from said inlet 15 is sent in the counter-clockwise direction by means of the unbinding rods 13 rotated at a high speed and is hit by the unbinding rods 13 repeatedly to perform an effective unbinding function, while a mass of noodles N is retained in a region near an entrance of the unbinding surface 17.
