Nonwoven machines are one of the most innovative areas of the textile sector. During recent years new fields of application, for example, geotextiles or filter media, have led to significant growth, but also require the constant further development of production and processing processes. Siemens’ automation portfolio provides machine manufacturers the necessary components to deal with these challenges.
With a precisely scaled modular kit, machine builders can combine exactly tailored system solutions for basic units such as mixers through to machines using complex movement profiles such as cross lappers. Automation solutions for the complete nonwoven line include integrated safety functionality, state-of-the-art communication via PROFINET, and arbitrary complex motion control.
Siemens is committed to helping you achieve superior performance and flexibility, easy and integrated engineering and worldwide product and application support.
Nonwoven formation is one of the most important process steps in making a finished nonwoven product. Therefore, the carding machine sets the foundation for the quality of the finished product. With the development of the high-speed carding machine and the design of an extra-wide carding machine (web widths greater than 5.5 yards), the worldwide trend is toward larger and more productive plants.
Siemens carding solutions offer a higher level of usability and flexibility through the consistent use of industrial standards. State-of-the-art machine communication provides excellent data management, data transfer and data and process image visualization.

Here the fibrous web is guided between the feeding and cover bands from the traversing upper carriage to the layering carriage, and is finally placed in a zigzag pattern on a take-off table that is positioned at 90 degrees to the machine axis. Larger laying widths, faster material throughput and precise nonwoven laydown are the most important requirements for the automation of a cross lapper, The speed ratio of the feed and take-off tables determines the number of layers, and thus also the material thickness.
