Machine for producing and treating a sheet of material
摘要:
A machine for producing and treating a web of material including a material web forming device, a dewatering and drying section, at least one application apparatus, a drying device and a processing device. The material web forming device forms a material web continuously from a supplied fibrous suspension. The dewatering and drying section is arranged along a material web path after the material web forming device. The section extracts water from the web by way of at least one of thermal and mechanical action. The at least one application apparatus is arranged along the material web path after the dewatering and drying section. The apparatus applies liquid or pasty application medium to at least one side of the web. The drying device is arranged along the material web path after the application apparatus. The drying device dries the moving material web to a final drying state. The processing device is arranged along the material web path after the drying device. The processing device at least one of processing, picking up and discharging the web. The at least one application apparatus includes at least one contactless application unit discharging application medium in a free application medium jet, an application medium curtain, an application medium veil or an application medium droplet spray. The at least one contactless application unit applying the application medium to the web on the basis of forces to the application medium, movement impulses imparted to the application medium and on movement of the application medium induced by the force of gravity.
