Abstract (en)

[origin: US4765272A] A device for the application of a thin layer of a coating material (7) onto a material web (2) passing across a backing roller (1) comprises a slot nozzle arrangement (3) having a nozzle slot (4). In order to ensure uniform and sufficient delivery of coating material (7) across the length of the nozzle slot (4), the coating material (7) is delivered from a supply container (8) through a delivery channel (10, 11) extending across the coating width to the nozzle slot (4) of the slot nozzle arrangement (3) and in the delivery channel (10, 11) of the slot nozzle arrangement (3) a gear pump arrangement (12) is provided which has a plurality of rectilinearly aligned pump sections (13), each having two intermeshed pump gears (14, 15), the arrangement extending over the coating width and arranged with the distance pieces mounting the pump gears (14, 15) between the pump sections (13) to be easily removable. The distance pieces (16) are formed as carbon bearings and the parts are channeled for heating and cooling.
