Device for the automatic rewinding of material delivered in sheets in heliographic and similar machines, particularly for heliographic machines for textile industries, comprising a winding member consisting of a hollow cylindrical casing with a C-shaped cross section, within which is rotatably mounted a shaft equipped with a plurality of radial tabs arranged at regular intervals along its entire length. The outer edge of the hollow casing and the tabs define a slot into which the leading edge of the sheet to be rewound around the hollow casing is initially inserted. The rotation of the shaft first causes the leading edge of the sheet to remain firmly gripped between the tabs and the edge of the hollow casing, and then pulls the hollow casing round, thus making the sheet of material wind around the latter.
