Schlumberger Redesigns Machine Drive Systems

France-based NSC Schlumberger recently introduced ProDyn®, a comprehensive, self-regulation control
system in machine and cross directions applicable to all nonwoven lines that make fiber batts using
a Dynamic card and a Dynamic cross-lapper.By redesigning the drive systems of the card and
cross-lapper, the system facilitates different fiber types, deniers, bonding systems and varying
product specifications. NSC Schlumberger claims the new system will consistently produce a quality
product while providing cost-effective and user-friendly production.
