An apparatus and method to net food products in shirred tubular casing, in
order to create a highly-dimpled foot product. A filling horn, shir
housing, and netting tube allow for the extrusion of food products into
an edible tubular collagen film, which itself expands into a netting of a
smaller diameter than that of the film. As the food product under
pressure expands against the tubular film, it presses through the spaces
in the netting to created a dimpled appearance. After the food product
has been further processed, the netting is removed, leaving the food
product with a highly-dimpled appearance.
