Latest Patents

One of Hans Jöhr's latest patents is a method for producing a rolled edge. This invention relates to the production of a rolled edge from an edge section of a tube. The process involves driving a flanging die onto the edge section to create a roll. A key feature of this method is that an initial area of the edge section is rolled in a positive fit manner using a forcibly controlled tool. This technique prevents buckling of the initial area, ensuring 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 by Jöhr is a method for producing lamella packets for adjustable steering columns. This invention involves at least one lamella being provided with a collar and joined to another lamella. The collar of the first lamella is supported against the other lamella, defining the width of the space between them. The lamellae are welded at the collar, preferably using resistance welding. This method allows for the use of the same material quality for all lamellae, which is advantageous in manufacturing.
