Rambold worked for the German company Teekanne since 1924. In 1929, he invented the tea bag packing machine called Pompadour. In 1949, being a co-owner of Teepack he invented a modern form of tea bag - bag with 2 chambers which remains the most popular type of the tea bag till now. In the same year he proposed a new tea bag packing machine Constanta which produced 160 bags per minute.[1][2]
