Abstract

A calender for treatment of a web of a nonwoven textile V made of thermoplastic fibers. The calendar includes a heated embossing roller made of steel and a counter-roller that runs at the same circumference velocity. The local plastification in the nonwoven textile V that is produced at the locations of the raised embossing areas results in a board-like feel of the nonwoven textile V. To reduce this hardness, the web of the nonwoven textile V is broken, after having cooled at least partially.
