Abstract: An automatic cop replacing apparatus for a shuttle-type loom with which a cop contained in the shuttle is automatically replaced, including tying the threads together of the old and new cops, and requiring no operator intervention. The apparatus includes a hand for gripping the cop, a rotary arm plate on which the hand is mounted, a drive device for rotating the rotary arm plate and for linearly moving the rotary arm plate in the axial direction with respect, thereto and a drive shaft for moving the rotary arm plate to an exchange position for the cop. A thread tying device holds and ties together the threads of the old and new cops.
