PFAFF Technology for documented sewing operations

Documented sewing reliability for the fast-growing automotive industry in China and Southeast Asia

(PresseBox) (Kaiserslautern, )
Docu-Seam-systems for safety-relevant seams in the automotive industry (e. g. side airbag) are a resource that every textile resp. leather-processing manufacturer of automotive interiors in Europe, America and Japan utilizes. The systems increase the process reliability and ensure a consistent seam quality by identifying and eliminating unusable seams in time. This is important with regards to product liability to counter and refute possible liability claims.

Due to the global network of automotive suppliers on the one hand and the growing awareness for automotive safety in China and Southeast Asia on the other hand, documented sewing reliability increasingly becomes a topic for models destined for the domestic or Asian market. With regards to sewing this particularly applies to both the car seat and the high-quality dashboard. PFAFF INDUSTRIAL in Germany has been engaged with the docu-seam-technology for almost 20 years and has steadily increased the functionality and of the PFAFF-solutions in a dialog with the European manufacturers. Today PFAFF INDUSTRIAL and their docu-seam systems without a doubt claim the technological leadership in this segment. The solutions are studded with unique technical features to ensure maximum process reliability.
