<p>Contour follower control device for use with cutting apparatus, of the type in which principal and complementary luminous flexes respectively provide information on the position of the copied contour and on future variations in its position, are swept by two eccentric modulating elements of a rotating modulator each acting on individual p.e recorders transforming the fluxes into elec. command signals for the servo-mechanisms of the p.e. copying devices. The eccentric modulating devices axes are situated in a plane passing through the axis of rotation of the modulator and on one side of it. The system allows information on variations in coordinates of the position of the copied contour to be assured.</p> |
