Abstract: The tray body comprises a support surface and a spring for spring biasing the tray door relative to the tray body to urge the tray door to open. When the tray door is fully opened, it rests against the support surface under the influence of a spring biasing force, provided by the spring, that exceeds a first non-zero threshold. The tray body comprises a tray frame and a door shaft that defines an axis of rotation of the tray door and the spring comprises a torsion spring arranged around the door shaft. The tray door comprises a shaft channel in which the door shaft is rotatably accommodated. The torsion spring has one end fixed coupled to the door shaft and another end to an inside wall of the shaft channel and/or the damper is arranged in the shaft channel and fixed in position relative to the door shaft.

Abstract: The present invention relates to a bomb bay sorter and to a tray to be used in such a system. According to the present invention, the tray body comprises a support surface and a spring for spring biasing the tray door relative to the tray body to urge the tray door to open. According to the invention, when the tray door is fully opened, it rests against the support surface under the influence of a spring biasing force, provided by the spring, that exceeds a first non-zero threshold.

Abstract: The invention relates to a method of protecting a camera (2) for inspecting printed work during printing from soiling. A transparent protective element (7) is placed here between the camera (2) and the printed work for inspection, and the protective element (7) is replaced when the transparency thereof decreases. The transparent protective element (7) can form part of a strip of transparent film (7) which is unwound from a supply reel (9) and wound onto a take-up reel (10). The decrease in transparency can be determined on the basis of a recording made by the camera (2). The invention also relates to a device (1) for protecting such a camera (2) from soiling, comprising a transparent protective element (7) to be placed between the camera (2) and the printed work for inspection; and means ( ) for replacing the protective element (7) when the transparency thereof decreases.

Abstract: The present invention relates to a camera system (1). The invention also relates to a color measuring system and a printing press provided with such a color measuring system and/or camera system. The focal distance can be determined by making use of a plurality of sensors (2, 2?, 2?, 2??, 15) to record an image of the printed image (8, 16, 17) printed by the press and determining the overlap (9, 9?, Ov) between these images (16, 17).
