nozzle design for a surface -mounted scaffolding and procedure for adjusting a width profile for a nozzle split,which is part of the jet construction

摘要

nozzle design (1) for a surface -mounted spray -suppression device for striking a paper /cardboard track,with the nozzle structure (1) at least two consecutive nozzle parts (2a, 2b,...(b) is in the running direction of the fibre line to be covered, with a nozzle split (3) between the nozzle parts extending in the transverse direction of the fibre line;that the nozzle split (3) by positioning an intermediate plate (8) between the adjacent nozzle parts (2a, 2b,...(8) is formed and the thickness of this intermediate plate determines the width of the nozzle gap, with the width profilethe nozzle splitter can be changed by using an intermediate plate (8) manufactured according to the desired profile, and the intermediate plate (8) is made by grinding.
