Embodiment Construction

[0093] In infrared emitters, a heating wire made of carbon or tungsten in the form of a coil or strip is enclosed in an emitter tube filled with an inert gas, usually made of quartz glass. The heating wire is linked to an electrical connection which is introduced via one or both ends of the emitter tube.

[0094] figure 1 A schematic view of a printing press in the form of a roll-feed inkjet printing press is shown, which is generally designated by the reference number 1 . From the unwinder 2 a material web 3 consisting of a printing substrate such as paper travels from the unwinder 2 to a printing unit 40 . The printing unit comprises a plurality of inkjet printing heads 4 arranged one behind the other along the material web 3 , by means of which solvent-based, in particular aqueous, printing inks are applied to the printing substrate.

[0095] The material web 3 then travels from the printing unit 40 via the deflection roller 6 to the infrared dryer system 70 when viewed i...

Abstract

Methods for drying a substrate having the following method steps are known: (a) emitting infrared radiation toward a substrate moved through a process space by means of an emitter unit, which comprises at least one infrared emitter, (b) producing at least two process gas flows of a process gas, which are directed at the substrate, (c) drying the substrate by the effect of infrared radiation and process gas on the substrate, and suctioning moisture-laden process gas from the process space via a suction channel, an exhaust air flow leading away from the substrate thus being formed. The aim of the invention is to specify, proceeding therefrom, a drying method that is reproducible and effective and that leads to an improved result in particular with respect to the homogeneity and quickness ofthe drying of the substrate. This aim is achieved, according to the invention, in that the at least two process gas flows are guided to the infrared emitter before the at least two process gas flows act on the substrate, and in that each process gas flow directed at the substrate is spatially associated with an exhaust air flow leading away from the substrate.

Description

technical field [0001] The invention relates to a method for at least partially drying a substrate, said method comprising the following method steps: [0002] (a) emitting infrared radiation to a substrate moving through the processing space along a transport path and in a transport direction by using an emitter unit comprising at least one infrared emitter, [0003] (b) generating at least two process gas streams of process gas directed at said substrate, [0004] (c) at least partially drying the substrate by the action of infrared radiation on the substrate and the process gas, and extracting the process gas containing moisture from the process space via an extraction duct, thereby forming a process gas from the substrate Exhaust flow drawn. [0005] Furthermore, the invention relates to an infrared dryer module for drying substrates which are moved through a process space in a substrate plane and in a conveying direction, said dryer module comprising: [0006] (a) an e...
