COMEZ takes over service for Müller warp knitting machines

Our subsidiary COMEZ International s.r.l., took over the After Sales Service for the RD3, RD3.8, RD3MT3, MDC and MDK machines as of February 1, 2019.

This strategic decision was taken to support our customers from the location with the highest knitting expertise in the Müller Group.

Please note: All orders placed with Jakob Müller AG Switzerland until 23rd January 2019, as well as all pending offers, will still be processed by our Swiss headquarters. However, we ask all customers to contact COMEZ International s.r.I. from 24th January 2019 onwards for parts orders or offers for the mentioned knitting machines.

If you have handled parts orders and technical queries through our local representative office in the past, you can of course continue do so.

If you were previously in direct contact with us as the manufacturer of these machines, you would need to contact in future our competence center for warp knitting machines, COMEZ International s.r.I. :


Tel.: +39 0381 698662

All contact information for COMEZ International s.r.I. can also be found on the COMEZ homepage:

Please note that customer service for RC, MDR and GWM remains with Jakob Müller AG in Switzerland.

MÜSONIC2 – Service Transfer
In future, Jakob Müller Germany will look after MÜSONIC2 machines

The new, ultrasonic MÜSONIC3 label slitting machine is manufactured by our subsidiary Jakob Müller Deutschland GmbH. This machine is closely related to its predecessor, the MÜSONIC2, and therefore it is only logical that in future the German company will also provide the after sales service for the older model. This change will take effect as from 1 January 2018.   

Any order received by Jakob Müller AG in Frick prior to this date, as well as all current quotations, will be dealt with by our Swiss headquarters. However, after January 1, we would request that customers working with the MÜSONIC2 contact Jakob Müller Deutschland GmbH with regard to spare part orders and technical questions.  

The complete Jakob Müller Deutschland GmbH address can be found on our website.
