A clipping device is provided for closing stuffed food casing with a clip and an apparatus is provided for causing a taped, holding string loops, to be directed toward the clipping device for closing an end of the food casing so that a string loop is transferred directly from the tape into an entry into a channel in the clipping device. The clip draws the loop to the casing and holds the loop to the food casing. The stuffing apparatus preferably also includes a novel readily cleanable food flow cut-off valve. A punch and clip anvil is provided to apply clips bent around the casing in essentially mirror image helixes. An extending and retracting conveyor is provided to remove stuffed food product from the vicinity of the clipping device after stuffed food casing is closed.
