Patent No. EP3868898 (titled "Machine For Finishing Hides") was filed by Gemata on Feb 5, 2021. The application was issued on Jun 1, 2022.
A hide finishing machine conveys hides via a rubber belt (1) pressed against an engraved roller (2) that deposits a liquid film (L) applied by blades (9). The belt is towed by a first roller (4) and returned by a second roller (5), where hides are transferred to a subsequent conveyor (6). One of rollers (4, 5) is a drive roller and the other is idle. To facilitate hide detachment without using a contaminating detaching roller, the second roller (5) utilizes a small diameter to induce longitudinal belt expansion. To counteract the resulting mechanical weakness and longitudinal flexibility of the small-diameter roller, the second roller (5) includes at least one supporting element (13) integral with a fixed machine frame, positioned between its two 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.
The dossier documents provide a comprehensive record of the patent's prosecution history - including filings, correspondence, and decisions made by patent offices - and are crucial for understanding the patent's legal journey and any challenges it may have faced during examination.
