Abstract (en)
[origin: EP0431275A2] The invention concerns a device for spreading of component webs (W1,W2...Wn-1,Wn), comprising a first, bowed, revolving roll (10) fitted at one side of the web (W) and a second, bowed, revolving roll (11) fitted at the opposite side of the web (W), as well as a swing mechanism (15,16,17), which is fitted to act upon said rolls (10,11) so as to alter the deflection angles (b1,b2) of the component webs (W1,W2...Wn-1,Wn) and thereby to produce the desired spreading (C) of the component webs (W1,W2...Wn-1,Wn). The device is provided with a regulation mechanism (12,13), which is fitted to correct the directional angles (g1,g2) between said rolls (10,11) and the web (W) to the desired values with all values of the deflection angle (b1,b2).
