Closure unit for end of casing used for making skinless sausages

摘要

A closure device for closing the closure end (3) of reusable cartridges (1) for producing skinless sausage has at least two convergent guiding tracks (10) which can be moved toward each other transversely to their longitudinal direction and which delimit an opening that surrounds the closure end and whose free cross-section can be reduced all around its circumference, in the manner of a shutter, when the guiding tracks are moved towards each other.
