A yarn changing set for color altering heads includes a yarn splint plate, a movable cutter plate, a yarn cutting plate and a yarn changing plate positioned in an overlapped manner. A plurality of pins are coupled between the yarn splint plate and yarn cutting plate to allow the movable cutter plate and yarn changing plate to move between them. The movable cutter plate and yarn changing plate have respectively a notch at one edge opposing each other to form a confined area to limit movement of the pins when driven by a cam. The yarn cutting plate has a plurality of accumulating portions to facilitate clearing of accumulated cotton. Therefore, smooth operation can be maintained and life span of the machine and elements increases.
