Abstract (en)
[origin: EP0347573A2] In a method for advancing the beginning of a web (1) of material, in particular a paper web, from below onto the roller (2) of a winding machine, the beginning of the web is moved upwards on a vertical guide plate (11) by means of compressed air. The compressed air is thereby blown upwards along the surface of the guide plate (11) and essentially parallel to the latter in an essentially laminar stream. Serving for carrying out the method is a device having a vertical guide plate (11), extending over part of the operating width, and having at least one flat jet nozzle (12) which has a plurality of upwardly directed blower openings arranged parallel to the guide plate (11), the distance of the blower openings from the guide plate (11) being less than 10 mm, preferably 0.5-1 mm. <IMAGE>
