ABSTRACT:
During the axial shirring of tubular casings into shirred strands while the material is inflated with air under overpressure, oil is intermittently injected without propellant air against the inside of the casing, so as to lubricate the inner wall of the casing. This eliminates the need for the costly construction required to provide for the discharge of excess air and oil needed with the known continuous oil injection through two-component nozzle with propellant air, and at the same time it insures a more uniform distribution of oil with reduced oil consumption. The injection nozzle is a single compound nozzle which is connected via electromagnetic valves to a conventional injection pump.
