Patents show the way forward


The Company was granted a second patent for Spiral brush technology and a patent for a paper and fabric moistener. A branch was set up in Schillingfürst (Bavaria) with round about 20 workers where car wash brushes and dandy brushes for horses were the main production.


Manufacturing continued under difficult conditions. Production was almost exclusively brushes for the armed forces and industries dedicated to the war effort.


Resumption and slow build up of production despite shortages of raw materials and restrictions due to the allied forces section borders.


A patent was granted for the Kullen Spiral brush machine under No. 814 137.


On the first of January 1952 the Company was changed into a limited partnership. It was now named Kullenbürsten Kullen & Co. KG.
