Abstract
A device for drying printed products in a printing machine having a transport device for conveying printed products along a given path includes a radiation device located outside the printing machine for generating radiant energy, and a device for transmitting the radiant energy generated by the radiation device to a surface of the printed product, the transmitting device being disposed at least partly in the printing machine so as to direct the radiant energy simultaneously over a defined width of the surface of the printed product.

Device for drying printed products in a printing machine having a transport device for conveying printed products along a given path, comprising a radiation device located outside the printing machine for generating radiant energy, and means for transmitting the radiant energy generated by the radiation device to a surface of the printed product, said transmitting means being disposed at least partly in the printing machine so as to direct the radiant energy simultaneously over a defined width of said surface of the printed product, said transmitting means comprising an elongated member having a substantially linear-shaped body with a fiber-optics cable having a multiplicity of optical fibers with ends thereof facing in a direction towards the printed product and being locatable above the surface of the printed product, and a transverse bar for arranging said ends of said optical fibers substantially along a line for directing the radiant energy linearly onto the surface of the printed product.
Device for drying printed products having an ink application thereon of varying structure in a printing machine having a transport device for conveying printed products along a given path, comprising a radiation device located outside the printing machine for generating radiant energy, and means for transmitting the radiant energy generated by the radiation device to a surface of the printed product, said transmitting means being disposed at least partly in the printing machine so as to direct the radiant energy simultaneously over a defined width of said surface of the printed product, said transmitting means comprising an elongated member having a substantially linear-shaped body with a fiber-optics cable having a multiplicity of optical fibers with ends thereof facing in a direction towards the printed product and being locatable above the surface of the printed product, sensor means for determining the structure of ink application on the printed product, and a control device for receiving signals from said sensor means corresponding to a determined structure of ink application on the printed product and varying the intensity of the radiant energy in accordance with the determined structure of ink application on the printed product.
Device for drying printed products in a printing machine having a transport device for conveying printed products along a given path, comprising a radiation device located outside the printing machine for generating radiant energy, and means for transmitting the radiant energy generated by the radiation device to a surface of the printed product, said transmitting means being disposed at least partly in the printing machine so as to direct the radiant energy simultaneously over a defined width of said surface of the printed product, said transmitting means comprising an elongated member having a substantially linear-shaped body with at least one gas-filled tube operatively connected to said radiation device for receiving therefrom the radiant energy generated thereby, said gas filled tube having an end, and fiber optics means connected to said end of said gas-filled tube facing in a direction towards the printed product and being locatable above the surface of the printed product for transmitted the radiant energy from said end of said gas-filled tube to the printed product.
