Abstract
An improved product filler collar is provided including an upper funnel portion for receiving charges of product from separate sources, guide ribs on the funnel portion for directing and controlling product flow and a neck portion for forming a single stream of product for filling a package or the like. The guide ribs may take the form of raised flanges forming a wall to confine relatively large product pieces. The flanges terminate in reduced extensions in the neck portion angled slightly back toward the product flow. The filler collar eliminates the bridging and swirling of product to prevent jams and decrease the residence time of the changes within the collar, thus improving the overall efficiency of the packaging operation.
