  • Method of dispensing a deformable and flowable filling material
    Patent number: 4617701
    Abstract: A method of dispensing pasty material, in particular sausage meat, is described in which the filled material is first introduced into a filling funnel, is preferably de-aerated, and is subsequently transferred into a filling cylinder, with the transfer being effected as a result of the pressure difference which prevails between the filling funnel and the filling cylinder. The dispensing of the filling material takes place in the customary manner by pressure applied to a filling piston provided in the filling cylinder.
