Top roller

Back to Blog

The top roller machines are designed so that the final glass thickness is already set in the tin bath. The standard at CNUD EFCO GFT is that all five degrees of freedom of the top rollers are automated: rotation, parallel stroke, nip angle, slew angle and penetration. The process is controlled remotely from the tin bath control room – no manual intervention is required.
There is a lot of potential for greater efficiency in this process, and CNUD EFCO GFT is already working on it: the top roller machines are an important part of camera-supported process automation, namely the real-time monitoring of process parameters and, if necessary, readjustment by the top roller machines to stabilize the glass ribbon.
