    摘要: A dusting device comprises a housing (12) and at least one powder gas delivery device (14, 15), which discharges a powder gas jet (16) onto a surface of products transported in one conveyor direction (18) and a suction device (34) for unused powder gas. At least one housing wall (21) is permeable for an airstream (28a), whereby at least one permeable housing wall (21) has an air-permeable filter mat arrangement (22).

    摘要: For powdering printed products it is proposed that they be moved through a nip formed by a powder application roller (38) and a support roller (32). Those two rollers have axial circumferential recesses (52, 54) which are each able to receive at least part of a gripper rod (24) moving a printed product and which are synchronized with the movement of a gripper rods. At a location upstream of the nip in the direction of rotation, powder is applied to the circumferential surface of the application roller (38) by a nozzle strip (62), which powder is then transferred in the passage nip from the application roller to the printed products.

    摘要: A device for measuring the surface of a print product, has a measuring head including a measuring light source and measuring light detector. The measuring light source and the measuring light detector each have a directional characteristic, the axes of which are set at different angles relative to the surface of the print product so that if the surface of the print product is ideally level and smooth, no measuring light reaches the measuring light detector. The axes of the measuring light source directional characteristic and the measuring light detector directional characteristic coincide adjacent to the print product, and both form an angle of less than 90 degrees with the surface of the print product.

    摘要: A powder-dusting apparatus (4) which inside a printing machine dusts the pre-dried printed products coming from the printing unit with a powder, for example of corn-starch, comprises in a manner known per se a plurality of nozzles (6), which are charged with a mixture of powder and carrying air from a mixing device (8). The nozzles (6) are arranged in the vicinity of the plane of transport defined by the transport system (1) of the printing machine and are able to assume two different spacings with respect to that plane: ordinarily the nozzles (6) are located comparatively close to this plane of transport; during these times the mixture of powder and carrying air emerges from the nozzles (6) towards the printed products moving past. If, however, a gripping device (2), which is part of the transport system (1) and which holds the printed product, enters the vicinity of the nozzles (6), a suitable control means (9 to 12) causes the nozzles to move into a second position. In this position there is between the underside of the nozzles (6) and the plane of transport of the transport system (1) sufficient space for the gripping device (2) to be able to pass.
