Abstract (en)

[origin: FR2770855A1] The invention concerns a card or any other apparatus for producing a web (1) feeding a distributor layer (2) two elementary webs (15a, 15b) constituting a lap web (16) deposited in reciprocating motion on a transverse output conveyor (26). In the apparatus (1) means for adjusting the speed of card doffers (13a, 13b), condensers (17, 18), web doffers (19a, 19b),cylinder (4) and/or feeder (7), and/or means for adjusting the cylinder-card doffer spacing affect the surface weight of the elementary web depending on the surface weight required at each point in the lap (67) width to be constituted on the output conveyor (26). The method consists in determining the delay incurred by each elementary web section for which the weight is being adjusted relative to the lap web being deposited; deducting therefrom the position where each web section will be deposited when the adjustment for its weight is carried out, thereby determining the weight adjustment to be applied thereto. The invention is useful for producing with high industrial flexibility laps with great variety of profiles.
