To provide a method for producing a non-woven fabric web from fibers, which enables a simple, fast and functionally reliable replacement of calender rollers during operation without bringing a device into a resting state.SOLUTION: There is provided at least one pre-fixation device 10 for pre-fixation of a non-woven fabric web 1, and there exists at least one first calender roller 13 for pre-fixation of a non-woven fabric web, the first calender roller being located downstream of the pre-fixation device. The first calender roller is replaced with a second calender roller 15 during operation of a process. In this case, the first calender roller is separated from the non-woven fabric web, and then during replacement of calender rollers, the pre-fixation of the non-woven fabric web is strengthened. After introducing the second calender roller, the pre-fixation of the non-woven fabric web is weakened again.SELECTED DRAWING: Figure 1 【課題】繊維から不織布ウェブを製造する方法であって、カレンダーローラの、簡単で、迅速でかつ機能的に信頼性のある交換を、装置を休止状態にすることなく稼働中に行うことができる方法を提供する。【解決手段】不織布ウェブ１の予固定化のための少なくとも一つの予固定化デバイス１０が設けられ、及び前記予固定化デバイスの下流の、不織布ウェブの固定化のための少なくとも一つの第一のカレンダーローラ１３が存在している。前記第一のカレンダーローラは、プロセス稼働中に、第二のカレンダーローラ１５と交換される。この際、前記第一のカレンダーローラは、不織布ウェブから離され、そしてカレンダーローラ交換の間に、不織布ウェブの予固定化が強化される。第二のカレンダーローラの導入後、不織布ウェブの予固定化は再び弱められる。【選択図】図１
