Lotustex Textile invests in KARL MAYER's first LINK-MATIC® system for automatic batch change on PRODYE®-S slasher indigo dye range

KARL MAYER has placed its first LINK-MATIC® system on the market. The sophisticated automation solution considerably simplifies the batch change on indigo and sizing machines, thus increasing productivity. An increase of up to 30 % is possible, depending on the number of batch changes per day.

Sales success of a solution for more efficiency in warp preparation

In addition, less yarn waste is produced. Up to 600 m, on indigo dyeing range, of unusable yarn material can be saved with each batch – while at the same time requiring less manpower. During batch changes, only one operator is required to prepare the warper beams for entry into the machine. A fully automatic knotting unit couples the warp yarns of the new batch to the yarns of the batch just finished.

Lotustex Textile has recognized all these advantages for itself. The Egypt-based denim manufacturer, which was only founded in 2019, was the first company to invest in the innovative LINK-MATIC® system in recent months in order to optimize the performance of its PRODYE®-S sizing machine. Especially for its activities in the fashion sector, Lotustex Textile expects a significantly higher flexibility and cost reduction. The delivery date for the new acquisition is November 2022.

Continuous processes with LINK-MATIC®

LINK-MATIC® makes it possible to automate the batch change on the PRODYE®-S and PROSIZE® with two subsystems. The first subsystem focuses on feeding the yarn sheets of the new batch from the warper beams to the infeed of the machine. The yarn material is guided to its destination in the lower section of the warper beam frame. Previously, it had to be threaded by hand, usually by two skilled workers, under the bottom cover. The lengthy, complicated process resulted in a batch of waste and numerous sources of error.

With the new solution, only one operator fixes the warp yarns of a warper beam in homogeneous distribution by a clamp in beam length. He then guides the clamp downward and hooks it into a transport chain on each side. The circulating chains take care of the transport to the machine. The time savings are immense. What's more, the quality is right. The yarns are guided to the machine with uniform, constant tension. Here, the second dividing system cuts the warp yarns of the finished batch at the infeed and knots on the warp yarns of the new batch - each with high precision and fully automatically. The actual batch change can thus be reduced to 90 seconds. What appears to be so simple is the result of the precise interaction of well thought-out components such as the clamping device for string formation before knotting and the pneumatic solution for sucking in the yarn ends.

The new LINK-MATIC® system can develop its full potential in conjunction with an moveable creel.

The newcomers HKS 3-M EL ECO and HKS 4-M EL ECO set new standards in the tricot market

Short development cycles, frequent pattern changes, and maximum efficiency – even with small batch sizes: Today's global fashion and apparel market demands more flexibility than ever before. High-performance warp knitting machines with compound needles (HKS) and EL pattern drive are KARL MAYER's answer to this challenge.

KARL MAYER celebrates 35 years of EL pattern drive

KARL MAYER is celebrating an anniversary this year: on 30 November 1990, the first warp knitting machine with electronic guide bar control, the KS 4 EL, was delivered – another milestone for patterning. As early as 1980, the SU gearbox with the MRS42SU had initiated the transition from mechanical chains to digital data.

India becomes growth engine for the warp knitting industry

ITMA ASIA 2025 exceeded all expectations for KARL MAYER – above all thanks to the strong interest from India: around 30% of the qualified discussions were held with partners from this traditional textile country. The response underlines the growing importance of the Indian market, which could become the second largest sales region for KARL MAYER after China. The warp knitting industry in particular is developing dynamically.

Solution for lower energy consumption proves itself in practice

Getzner Textil is one of KARL MAYER’s first customers to use PROSIZE with CASCADE. The innovative weaving specialist has tested the steam and condensation system by KARL MAYER and determined the energy savings it achieves. Karl-Heinz Vaaßen, Head of Textile Drying at KARL MAYER, assisted Getzner Textil’s production specialists both with the tests and with all questions relating to CASCADE. In a conversation with Werner Egger, Head of Weaving, and Thomas Rossi, Head of Warp Preparation at Getzner Textil, he learnt more about the system’s benefits for his customer.
