Patent No. EP4149286 (titled "A Device And A Method For Forming Tips Of Rod-Like Article For Tobacco Industry") was filed by Tobacco Machinery Poland SP Z OO on Apr 30, 2021. The application was issued on Oct 29, 2025.
A device for forming tips of rod-like articles, such as tobacco industry cardboard tubes, comprises a drum conveyor with at least one flute for transferring articles transversally to their axis along a first circular path. Coaxial to this path are a first and second pressing element moving along second and third circular paths, respectively, positioned opposite each other. At least one pressing element features a concave forming surface. These elements move linearly along the flute's axis, transverse to the first circular path, toward and away from each other. The device is configured to form a crimped tip at an article end, creating an opening with an inner diameter smaller than the article's central section inner diameter to prevent filling material loss or segment intrusion.
