Abstract
A device for forming rolled sheet articles, such as cookies, which are rolled after heating, comprises an endless conveyor which has a surface on which the article is placed and which is continuously advanced at a predetermined speed. The article is moved substantially tangent to a periphery of a roll-up roller which is rotatably mounted alongside a portion of the conveyor and is spaced less than the width of the sheet article thickness from the conveyor. The roll-up roller is rotated at a slower speed than the movement advance of the surface and it engages the sheet article or cookie and causes the bending thereof around its surface. A roller board is arranged adjacent the roll-up roller and it includes a stopper which prevents complete rolling of the article around the roll-up roller and instead deflects it forwardly in the feed advance direction of the conveyor. A friction surface is arranged above the conveyor and it is either stationary so that it provides a drag on the periphery of the partially rolled up article so as to complete its rolling during the advancing movement of the conveyor or it is moved in a direction and in an amount to cause a frictional drag on the peripher…
