Abstract
The invention provides a device for removing individual covers from a continuous flow of covers, each consisting of a middle portion and a peripheral edge extending around it asymmetrically in relation to the main plane, the main planes of which covers extend perpendicularly to the conveying direction, while the nominal orientations of the covers in the conveying direction are all the same and the said individual covers are oppositely oriented in relation to the nominal orientation, the device includes a conveyor for transporting the covers in a continuous flow, a detector placed adjacent to the conveyor for distinguishing an oppositely oriented cover and an ejector for removing from the flow a detected oppositely oriented cover.
