Unwinders and changers – the heart of uninterrupted production

Modern SINTIA solutions for the paper and printing industry
The unwinder, changer - and in international terminology known as Splicer - is one of the key devices in the technological lines of the paper and printing industry. Its role is invaluable wherever continuous feeding of material from the roll is necessary with simultaneous, precise tension control and the possibility of automatic change of the ending roll to a new one, without the need to stop the production process.

In the era of growing requirements for uninterrupted operation, reliability and precision, modernization of older devices of this type is becoming essential. SINTIA, responding to market needs, has already implemented dozens of comprehensive modifications of changers and unwinders, replacing outdated drive systems and control systems with modern technologies from renowned manufacturers such as Mitsubishi Electric or B&R Industrial Automation.

Experience and quality

Devices from companies such as Winkler + Dünnebier and STORK Contiweb enjoy a reputation for being extremely durable and solid. Their mechanical design often does not require major changes even after many years of operation. Unfortunately, the same cannot be said about outdated electrical, control and drive systems, which lose their reliability over the years, become difficult or impossible to service, and their spare parts are unavailable. Thanks to the modernization solutions we have developed, SINTIA has breathed new life into many of these types of devices, significantly improving their reliability, functionality and compliance with current safety and efficiency standards.

Innovative technical solutions
The example of the WD191 model shows how much the functionality and reliability of the changer changes after modernization. Modern servo drives, advanced PLC and HMI systems, and proprietary software developed by SINTIA engineers eliminate many typical problems that users of these machines had to face in the past – such as uneven material tension, imprecise positioning, or failures related to component wear.

We are trusted by industry leaders.

Companies that have decided to modernize unwinders and changers with SINTIA unanimously emphasize high reliability, greater efficiency and a noticeable increase in operator comfort. Our satisfied customers include:
