  • Patent number: 8853973
    Abstract: Each screen (1) of a group of screens is configured by a method in which a function is approximated, the function giving the instantaneous axial position (H(t)) of the load bar (2) thereof along an axis (Z) of translation in the form of a function having, as a variable, the instantaneous angular position (y(t)) of a winding device (4). The load bars of the screens are sequentially moved into a plurality of positions in which the load bars are aligned, and then the angular position (y(t)) of the winding device is determined. Next, the coefficients defining the approximation function of each screen are determined. The movement of the load bar of each screen is controlled by an instantaneous angular-position set value (?(t)), which is in turn predetermined from a representative profile using the one-to-one approximation function.
