Groz-Beckert develops innovative new products together with Mayer & Cie.

Albstadt, Germany: Together with the German circular knitting machine builder Mayer & Cie., Groz-Beckert has developed the optimized Relanit sinker SNK F over the past years. Independently of this, the development of the new LCmax™ energy-saving needles took place. The focus of both developments is on efficiency, energy savings and increased process reliability.

Groz-Beckert offers interested machine builders different cooperation options to jointly develop new products or optimize existing ones. The Groz-Beckert Technology and Development Center (TEZ) provides the appropriate framework for so-called co-development projects. At the ITMA in Milan in June 2023, Groz-Beckert presented some of the successful cooperations under the motto "Innovation through cooperation". Among them were two new developments realized with Mayer & Cie. Groz-Beckert presented the two new products for the first time in Asia at ITMA Asia in November 2023.

Optimized Relanit sinker SNK F

At the end of 2018, circular knitting machine manufacturer Mayer & Cie. approached Groz-Beckert with a request to jointly develop an improved and more efficient sinker for selected machines of their Relanit family that would run more smoothly and reliably in the needle tricks. The innovative sinker has an integral spring with a spring force that is adapted to the sinker thickness. Field tests were consistently successful and confirmed the functionality and advantages of the new sinker.

Thanks to their unique, adapted spring, the newly developed SNK F Relanit sinkers are securely guided while they are running through the cam track, resulting in a quieter operation. This increases process reliability and ensures an improved loop structure. In addition, wear on the swivel butts of the sinkers is reduced. This increases service life and makes the process more sustainable and cost-efficient.

Higher energy efficiency thanks to LCmax™

The second recent cooperation with Mayer & Cie. was initiated by Groz-Beckert. With its products, Groz-Beckert strives to provide textile producers with the best possible support in meeting the constantly growing demands for sustainable production. Accordingly, the topic of sustainability has always been a focus of new and further developments at Groz-Beckert.

The objective was to develop a cost-effective energy-saving needle. After considering various variants, the common choice of Mayer & Cie. and Groz-Beckert was the LCmax™ knitting machine needle with innovative, wave-shaped shank geometry. The first prototypes were extensively tested on laboratory machines at Groz-Beckert's TEZ. The trials confirmed the advantages of the new technology.

The innovative, wave-shaped shank of the LCmax™ needle ensures a smaller contact area of the needle in the needle trick. This results in less friction, which reduces machine temperature and enables energy savings of up to 20 percent compared to a standard needle. This saves costs and at the same time allows operation of the machine at the maximum possible speed.

In both projects, the cooperation between Mayer & Cie. and Groz-Beckert went far beyond mere product development. In addition to Applications Engineering and Construction, the companies' Sales and Purchasing departments were also involved in a close exchange. The cooperation at all levels was characterized by openness, constructiveness, partnership and goal orientation, and led to successful results from which the customers of both companies can now benefit.
