Hook groups formed by hooks in a number identical to a maximum number of loops of sausage to be suspended from a stick are provided on a wrapping connector moving body of a conveyor with a respective hook absent zone interposed between adjacent ones of the hook groups. When the sausage is suspended from all the hooks of one hook group, the supply of the sausage to the conveyor is interrupted, and the sausage whose supply to the conveyor has been restarted after the hook absent zone moved a predetermined distance is suspended from a first hook of an ensuing hook group to form one loop by a last hook of the one hook group and a first hook of the ensuing hook group.
