Inspection lines for automotive strip

Inspection lines from ANDRITZ Sundwig, placed at the end of the processing line, are sections to check the quality and results of each treated coil. The wide range of our finishing portfolio provides solutions for every requirement.

Product description

Inspection lines come at the end of a long process chain. The wide strip is inspected and conditioned here. Visual surface inspection or inspection assisted by automatic equipment makes product quality controllable and the results recordable for every single finished coil. This provides reliable quality data.

Large coils can be cut into smaller or medium-sized coils, and defective strip parts can be eliminated and used for lower-grade requirements. Trimming, center-cut, strip signature, thickness measurement, greasing – nearly anything is feasible: double uncoiling groups, automatic coil opener and transport system for both coiling directions, or separate coil sleeves for A and B grades with reverse transport to the welding machine.

ANDRITZ offers mature automation equipment with integrable level 2, thus providing an attractive solution for each and every requirement. Patented units ensure maximum flexibility.
