Patent No. EP4303141 (titled "Separating Device For Separating Portions From Elongated Casings Filled With Food Mass, Corresponding Crimping Element And Method") was filed by Vemag Maschinenbau on Jun 30, 2023. The application was issued on Jan 29, 2025.
A separating device for portioning food-filled elongate casings, such as alginate sausages, comprises two spaced, circulating transport elements driven by at least one drive. These elements feature transport and return regions, oriented to reduce the distance between them along the transport direction. Each transport element carries at least one laterally protruding crimping element. Each crimping element includes a fastening section, a crimping section with two arms opening from a main section, and a counter holder. The counter holder presses the opposite crimping element's crimping section with a contact force during convergence. Crucially, the counter holder is flexible, applying a preloading force to the opposite crimping element to enhance the separating effect and ensure complete sealing of the casing ends.

Patent oppositions filed by competitors challenge the validity of a granted patent. These oppositions are typically based on claims of prior art, lack of novelty, or non-obviousness. They are a key part of the process for determining a patent's strength and enforceability.
