With regard to pillow plates, we work with a supplier who is one of the pioneers of this technology. On the cylinder or funnel plate of t = 3mm or t = 4mm, a sheet of t = 1mm is placed. The welding is done by an advanced laser welding technique. An advantage of this welding technique is that there are no deformations due to welding distortion. Thus, the inner wall of the cylinder remains absolutely straight, accordingly, an optimal stripping is guaranteed.
