METHOD FOR THE MANUFACTURE OF FLUTING OR TEST LINER

摘要

The invention relates to a method for the manufacture of fluting or test liner. The method comprises treating a fibrous web in at least one process step with a metal belt calender, comprising a metal belt (2) adapted to circle around at least one guide element (3), outside said belt being provided at least one counter-element (5) establishing a contact surface with the belt, such that the belt (2) and the counter- element (5) establish therebetween a web treatment zone of adjustable length, the web to be treated being passed therethrough. The method comprises setting a web dwell time in the treatment zone at about 5-200 ms, setting the metal belt and/or the counter-element at a temperature of about 20-400°C, and regulating a contact pressure applied to the web within the treatment zone over the range of about 0.01 MPa to about 200 MPa.
