Latest Patents

One of his latest patents is a method for producing a rolled edge. This invention relates to a method for the production of a rolled edge from an edge section of a tube. In this process, a flanging die is driven onto the edge section, flanging it into a roll. The innovation involves rolling an initial area of the edge section in a positive fit manner using a forcibly controlled tool. This technique prevents buckling of the initial area, which maintains a controlled geometry as a result of rolling. This novel method is particularly useful in the production of valve seats in aerosol domes for spray cans.

Another significant patent is a device for the ejection of moulded pieces from a moulding tool. This invention features a spring cushion designed for the ejection of moulded pieces from a moulding tool. It includes a plunger that moves within a guide tube and is loaded in the ejection direction by a spring. The innovation here is that the spring is designed as a draw spring, specifically a spiral draw spring. This design allows for a considerably longer service life, as draw springs do not experience radial deflections when loaded.
