SHW is one of the oldest companies in Germany. In 1365, SHW was founded by the Zisterzensien monks when they were given mining rights by the King. The plant later belonged to the Dukes of Wuerttemberg. Then, with the coronation of Friedrich I, the plant became known as Königsbronn or, the “King’s Fountain,” which is still the name of SHW’s foundry in Germany today. SHW is an abbreviation for Schwabische Huttenwerke, which roughly translated means “Swabian Iron Works.” Documentation in 1665 shows proof of the first casting in chills, which was used for a cannon. Chilled cast-iron rolls have been manufactured since 1832, and the first calender roll for a paper machine was finished three years later.
Since then, the Königsbronn Plant has specialized in calender rolls for the paper industry and has become the world leader in this field. In 1885, SHW won a gold medal at the Paris World’s Fair for Calender Rolls. At SHW, more than 75,000 chilled rolls have been manufactured in 170 years. Königsbronn has pioneered the application of heated calender rolls for improving the smoothness and the gloss of paper.
Now, about two out of every three heated calender rolls in state of the art paper machines around the world are marked with the "royal crown." This Königsbronn inspector's stamp is proof of having passed all rigid quality checks.
In 1985 SHW expanded to North America when they purchased the roll division from the Farrel Corp., located in Ansonia, CT. In 1991 a new, 50,000 square foot facility was specially designed and built in Torrington, CT. Hard surfacing capabilities were added in 1995 by the addition of 10,000 square feet. This facility offers complete calender roll manufacturing, as well as roll services and repairs.
