Crosslapper

Profile crosslappers Profile for high productivity: The ANDRITZ Nonwoven crosslapping technology is based on 60 years of experience and continuous innovations.

Today ANDRITZ offers you the complete eXcelle crosslapper range.

Thanks to its short textile path, profiling capabilities, and infeed speed, the Profile crosslappers range perfectly matches the new production lines requiring higher productivity and web weight profiling improvements.

PROWI D The ProWid control system is a tool that regulates the card web weight before the web enters the crosslapper in order to lay a fiber mat with lighter edges. It thus anticipates later fabric deformation caused by the bonding process. The CV percentage is generally improved by a factor

ProWid can be delivered with an individual ANDRITZ crosslapper to enhance performance in existing carding lines or with new needlepunch aXcess lines.

Profile crosslappers ANDRITZ ProDyn: Dynamic motion from card delivery and Profile crosslapper contribute a remarkable reduction in production costs thanks to the improved fabric weight evenness. The ProDyn is designed to work with Dynamic eXcelle cards and a scanning gauge for fully automatic, closed loop control.

PRO DY N The ProDyn system combines actions from the card doffers and dynamic speed variation at the crosslapper. It allows you to generate a fiber mat with lighter edges and a heavier center area, anticipating subsequent fabric

deformation during the bonding process (no “Smiling effect”).

To minimize cloudiness and variations in fabric behavior, the fiber mat is formed with card web layers with the same consistency and low fiber tension.
