Abstract

Appts. for producing a water curtain for cooling workpieces comprises several water boxes each having their own feed supply with a syphon-like overflow inlet into the slit nozzle outlet. The joining area between adjacent water boxes is built as a tapered bulkhead with inclined sides in which the width of the slot outlet in this joining area is locally restricted.
