Apparatus and method to net food products in shirred tubular casing

In combination, an apparatus to net a food product, a casing and netting, comprising:

• a casing having a filled dimension when filled with a food product;
• a netting having an outside dimension less than said filled dimension;
• and
• an apparatus including:
• a filling horn defining a bore for receiving extruded food products and having a cross-sectional dimension, said filling horn receiving said casing, said filled dimension of said casing being greater than said cross-sectional dimension of said filling horn,
• a shir housing mounted coaxially to said filling horn and having an outside dimension greater than said cross-sectional dimension of said filling horn, and
• a netting housing attached to said shir housing coaxially to said filling horn, said netting housing comprising a netting tube and a tube holder, said tube holder comprising an attachment disc defining an annular aperture, a downstream ring, and a plurality of rods connecting said attachment disc to said downstrean, ring, said attachment disc being mountable to said shir housing so that said filling horn protrudes through said annular aperture and through said downstream ring, said netting tube comprising a tubular section and a base plate, said tubular section having an inside diameter and an outside diameter, said outside diameter of said tubular section of said netting tube being less than said outside dimension of said netting, said netting tube being mountable over said tube holder and said base plate being mountable to said attachment disc, and said tubular section being configured for receiving said netting,
• whereby food products extruded from said filling horn into said casing expand said casing against said netting to create a dimpled appearance in the food product.
