    Tin bath top roller machine used in float glass manufacturing process to control the thickness and width of glass ribbon

    Automatic top rollers move the glass ribbon forward as it floats on the molten tin. By adjusting how fast the rollers turn and the angle at which they run, operators can control the thickness and keep the sheet width steady.

    The automatic top rollers can produce float glass as thin as 0.12 mm. Their main features include:

    • Compact design: the narrow width makes it suitable for installations where space is limited.
    • Stable operation: radial runout of the rollers is kept within ≤0.1 mm, ensuring smooth performance.
    • High precision: linear motion errors are controlled within ±0.1 mm, with the same level of repeatability.
    • Reduced heat loss: roller rods are fitted with insulated water jackets to maintain stable forming conditions.

    To keep raw materials flowing evenly, the system uses two drive stations and three clutches that can be combined in different ways. This makes the feeding shovels move together in sync, so the material is delivered continuously without interruptions.

    The box is built with precise welding, so it doesn’t bend or lose shape, and then it’s heat-treated to make it even stronger. Inside, stronger stainless-steel plates are used, which can handle high temperatures without losing stability. This makes the box more reliable in daily use and lowers the risks that usually come with long-term operation.

    The lift-out roller table is built with a steel frame that has a circulating water system inside. This cooling setup prevents the frame from bending or losing shape when exposed to high heat. The bearings are also water-cooled, which reduces wear and extends their service life. Thanks to this design, the machine can keep running reliably even during long periods of continuous production at high temperatures.

    The stirring depth can be adjusted depending on production needs. As the blades move, they generate vortexes in the molten glass that collide and mix together. This motion helps mix the molten glass thoroughly, making sure it stays even in both composition and quality before it goes into the forming stage.
