The paper valve bag finally replaced the open cotton sacks. Recognizing the opportunity for Haver & Boecker, the Managing Directors of the second generation accepted the tender to build the packing machines for paper valve bags under license and sell them on the European market.
The first packing machine delivered from the USA could not be used unchanged in Germany due to the strict calibration regulations. Haver & Boecker extensively refined the packing machine – thereby acquiring a good reputation in the packing machine business. As a result, the American licensors ordered machines in Oelde.
Nevertheless, major technical difficulties were encountered when attempts were then made on site to modify the machines for American conditions. Alfred Bruder, an ingenious designer and technician, embarked on a voyage to America. He managed to make the technical changes and build more machines on site using the knowledge he had gained. Satisfied, he was able to make his way home to Germany on May 12, 1939. A short time later, the Second World War broke out and all connections to America were interrupted during the course of hostilities.
