web transport belt 11 layered by roller 16 if the speed at which web transport belt 10 is driven by its drive roller 32 is as high as the movement speed of pivot frame 7 since the fiber web is discharged at this speed from discharge nip b the section of web transport belt 11 resting on the freshly layered web does not have a relative speed with respect to the web except for the movement of output conveyor 6 transverse to the layering direction of layering arm 3 during this movement transport belt 10 has a speed relative to speed at take up site a zone which consists of the sum of the running speed of pivot frame 7 and the supply speed of transport belt 10 the same applies to transport belts 10 and 11 for movement of pivot frame 7 in the reverse direction practice has shown that this relative speed between the layered fleece and transport belts 10 and 11 covering the layered fleece does not lead to problems as mentioned above pivot frame 7 is pivoted with respect to layering arm 3 around a horizontal axis so that the deflecting roller 16 or 17 which is in front in the moving direction is slightly lifted the section located between take up site.
