It must have been a day in 1951, when Rolf Heim said to himself “I will dedicate my life to making tubes”.

Maybe this is not exactly what happened, since the origin of the Siegfried HEIM GmbH Kroneckwerkstätten, lies in the production of contact tubing for textile coils. Yet there were the conical tubes for the chairs and sofas typical of the 60’s and someone had to take care of those.

That’s how Rolf Heim ended up making tubes. Another invention the company came up with were cable fittings for electrical installations, which were registered under the name of “Kroneck”.

Later there wasn’t much left of the old workbench, which had started everything. The business got bigger, the machines became more modern and the product spectrum became more extensive.
