Abstract (en)
[origin: WO2012107486A1] The invention relates to a method and device for strengthening, in particular needling, a continuously fed material web (21), wherein the material web is strengthened in a strengthening zone and is drawn out of the strengthening zone by a drawing apparatus (24). At least one parameter, in particular the material speed, of the strengthened material web (21) is detected in a guiding zone arranged downstream of the fastening zone and before the drawing apparatus (24) by means of a measuring apparatus (22), preferably without contact, and is optionally used to control the strengthening apparatus.
