The machine building company is founded by Dipl.-Ing. Bernhard Tellen in Kalkriese near Osnabrück as a one-man company. Shortly afterwards the company moved to the town of Alfhausen-Thiene.
First employee is hired. More specialists are hired over the years that follow. The facilities in Thiene become too small.
Company of 9 employees moves into their own production buildings with a production hall and office area at Industriestraße in the town of Alfhausen.
The first apprentices as machine building technicians are brought on board.
Second production hall is built in order to keep up with the new market demand of the new states of former East Germany. At this time 14 employees are employed in the company.
The first production systems are exported to foreign countries.
Our production systems become more comprehensive as the wish by customers for complete systems increases. More personnel join the company.
A third production hall and larger office space are built. More and more orders from foreign countries drive business.
Company restructures from Bernhard Tellen company to Tellen Maschinenbau GmbH & Co. KG, and continues to be managed by Bernhard Tellen. Approximately 50% of sales are generated by export.
A fourth production hall is added, thus expanding the production area to 2,500 square meters.
Office space expands to 400 square meters. 50 employees are working in the company.
Daughter Dipl.-Ing. Lisa Kenning and son Dipl.-Ing. Johannes Tellen join the company.
Production and assembly areas grow to 4,700 square meters.
Lisa Kenning and Johannes Tellen granted power of procuration. Company is named as “apprenticeship-provider of the year” by the education region of northern Osnabrück.
Tellen Maschinenbau invests in a 7-axis travelling milling machine with a 7 x 1.5 meter travel range.
85 workers, among them 15 apprentices, work in the company.
