emco IAS Cockling Tester

The emco IAS Cockling tester determines the cockling potential which is generated in the drying section of a paper machine.

With climate changes under absence of tension, paper shows cockling which is expressed locally by bubble content and globally by waviness.

Cockling is shown extremely with climate changes from 70 % rH and 23 °C. It works by releasing of the dried tensions between the fibers.

Released bubble content remains, the waviness is reduced with the drying process due to the shrinkage.


  • Measuring surface: 180 mm x 180 mm
  • Optional: climate chamber for determination of cockling potential

Cockling quantities

  • Cockling index
  • Waviness as index
  • Bubble content as index

The cockling index and additional parameters for the waviness and the bubble content are calculated.


  • Quality control for paper manufacturer
  • Control for further processing
