A recently granted patent (Publication Number: US11851359B2) discloses a device for reshaping a rotating glass intermediate, featuring at least one shaping roller that can be translationally displaced into shape-rolling contact with the glass intermediate for shaping. The device includes a linear motor for positioning the shaping roller, with a measuring system comprising an optical measuring unit and a measuring strip to measure the translational movement of the translator. The measuring unit or strip is fixedly connected to the translator to directly follow its movement, allowing for precise shaping of the glass intermediate. Additionally, the device may include a roller motor for rotating the shaping roller, radial bearings, and linear guides for guiding the translator and shaping roller along an axial feed axis.

Furthermore, the patent also covers a system for producing rotationally symmetrical glass products, incorporating the reshaping device described above. The system includes a receptacle for holding the glass intermediate, the reshaping device with the shaping roller and linear motor, and a carousel for moving the receptacle to different manufacturing stations or moving the shaping roller to different receptacles for glass intermediates. This innovative system allows for efficient and precise reshaping of glass intermediates to create rotationally symmetrical glass products, with the ability to move the shaping roller to different receptacles for increased flexibility in the manufacturing process.
