Convonic Engineering was founded in 2014 in Wuppertal as a successor to the "Gebr. Nadzeyka Maschinenbau GmbH".

Convonic continues the engineering work of Nadzeyka after restructuring and continues to develop the established technologies.
Of course, Convonic also carries out after-sales service and support for all supplied Nadzeyka machinery.
This also applies to complete machine overhauls including renewal and modernization of control technology.

Convonic is thus a specialist for paper processing machines especially for the production and processing of paper tubes, based on almost 50 years of experience and know-how of the Nadzeyka company.
