Abstract

A.L'INVENTION CONCERNE UN ROULEAU TENDEUR DES FEUILLES SUR LES MACHINES A IMPRIMER ROTATIVES OU AUTRES AGISSANT PAR MODIFICATION DE SA CIRCONFERENCE ET PAR SUITE DE SA VITESSE CIRCONFERENTIELLE. B.ON MONTE SUR LE ROULEAU UNE ENVELOPPE ELASTIQUE SEPAREE PAR UNE FENTE ANNULAIRE ET QUI PEUT SE DILATER SOUS L'EFFET D'UNE PRESSION INTERIEURE TOUT EN CONSERVANT SA FORME CIRCULAIRE. C.CE ROULEAU TENDEUR PERMET DE MODIFIER LA VITESSE CIRCONFERENTIELLE SANS AVOIR A FAIRE APPEL A DES DISPOSITIFS COMPLIQUES ET ENCOMBRANTS ET TOUT EN EVITANT LES VIBRATIONS DE LA BANDE.A. THE INVENTION RELATES TO A SHEET TENSIONING ROLLER ON ROTARY OR OTHER PRINTING MACHINES ACTING BY MODIFICATION OF ITS CIRCUMFERENCE AND THEREFORE OF ITS CIRCUMFERENTIAL SPEED. B. AN ELASTIC ENCLOSURE IS MOUNTED ON THE ROLLER SEPARATED BY AN ANNULAR SLIT AND WHICH CAN EXPAND UNDER THE EFFECT OF INTERNAL PRESSURE WHILE RETAINING ITS CIRCULAR SHAPE. C. THIS TENSIONING ROLLER ALLOWS THE CIRCUMFERENTIAL SPEED TO BE MODIFIED WITHOUT USING COMPLICATED AND BULKY DEVICES AND WHILE AVOIDING BAND VIBRATIONS.
