Abstract: This display panel for a plurality of posters to be displayed sequentially comprises a pair of spools, namely a feed spool and a take-up spool, and drive means for causing each spool to become by turns the feed spool and the take-up spool, and means for automatically correcting the lateral shift of the poster band by reducing the tension exerted on the paper on the side opposite the buckling side, or, in other words, for creating on the side opposite said observed buckling another compensating effect buckling so as to change the orientation of said shift, which in any case is detected by means known per se; the correction means are such that they modify the inclination of one spool in relation to the other in the poster plane in order to reduce the distance between the axes of the two spools on the side opposite the buckling of said poster band which is due to a reduction in the paper tension.
