Karli began his apprenticeship as a technical draughtsman in 1970. Back then, he had been personally hired by Georg Utz himself. A smile wreathes his face. And a little pride. The offices were equipped with drawing boards. There were as yet no computers with modern CAD software, nor were there pocket calculators. Everything had to calculated manually and preconceived. Rather "old school".
Karli likes to remember the patron: Georg Utz was a doer and a designer. A born inventor. He invented everything from basement shelters to rabbit hutches, letterboxes, chicken baskets and pallets. Almost everything made of plastic and intended for the storage and transport of objects and animals. Some of these items are still being produced today. The plastic container RAKO, for example, manufactured in 1965, hit like a bomb. A box-office hit to this day, it is available in almost every Swiss household. And who’s surprised? In a way, the frame construction embodies the Utz company and its founders: stable and straightforward.
His most famous and one of the most revolutionary inventions was the zigzag stitch for sewing machines. Thanks to his zigzag plate, even conventional sewing machines could perform a zigzag stitch without a laterally movable needle.
