  • Carrier for flexible printing plates
    Patent number: 3941055
    Abstract: A flexible printing plate carrier comprises a curved carrier plate at least one end of which has mounted thereon a rotatable tubular shaft having an axially extending projection about which a bent over end of the printing plate can be hooked. A pre-loaded torsion spring extends through the tubular shaft to urge the projection towards an edge of the carrier plate and to clamp the printing plate against said edge. Rotation of the shaft to the non-clamping position of the projection is effected by a hand tool insertable into a bearing for one end of the shaft.
