Abstract (en)
[origin: US2007261220A1] In a former known hydrodynamic needling device the material web which is meant to be consolidated or finished shall be drawn-in totally or just partly, thus automatically, by an auxiliary material-web drawing-in device. The auxiliary device can work with a frontrunner which is affixed at the beginning of the material web, and which is retracted into the whole machine, or only one part of the non-accessible, if applicable, rollers are driven round by an auxiliary device and the material web is therewith threaded in the provided material-web track.
