Patent number: 5053239Abstract: The invention relates to a process and apparatus for producing a sausage package containing up to about 30 sausages wherein each sausage is individually packaged in packaging films. The sausages are produced directly into the packaging films to be cooked while being retained within said films. Suitable sized packages including one or more sausages may be cut from the length of packaging film including the individual sausages. The unique possibility of producing several parallel sausages is obtained by sealing off the individual sausages from continuous parallel packaging film tube by sealing and shaping molds forming the rear end of one stuffed row of sausages and the fore end of the next row of sausages to be stuffed.Type: GrantFiled: July 27, 1990Date of Patent: October 1, 1991Assignee: Food Systems Industries Oy, Ltd.Inventors: Pentti J. Vanhatalo, Visa A. P. Krappe
