Welding robot for watermark production

During paper manufacture, parts of the watermark on security paper are created using so-called "e-types". For this, these sheet-formed characters have to be welded onto the filter holder of the paper machine – until now individually by hand, using tweezers. With up to 3,200 elements per filter, this takes a great deal of time! The welding robot developed by tech-solute reduces the effort involved by around 70%. The e-types are welded onto the filter completely automatically. The entire project was realized by tech-solute from a single source – from project planning via mechanics and electronics development, construction of the machine and documentation, all the way through to the patent registration for the customer.
