Flammespærreanordning og fremgangsmåde til udformning af boringer i flammespærreanordningen

摘要

#CMT# #/CMT# A boring (6) insertion method requires total axial closure of the coiled flame trap arrangement (1), which consists of two coiled metal strips or bands with a circular outer periphery. Total closure on both sides is achieved with retention plates (5), and from the outer periphery the boring is inserted radially inwards with a spark erosion electrode (7) under the effect of a coolant liquid. #CMT# : #/CMT# An independent claim is included for a flame-trap consisting of two coiled metal plates formed, in common, into a disc with circular outer periphery. #CMT#USE : #/CMT# For inserting radially directed borings for fixture pins in flame trap. #CMT#ADVANTAGE : #/CMT# Facilitates tight fixture of the windings of a coiled flame trap arrangement. without risk to the shape of the entrance gaps. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# A schematic representation of a coiled flame trap is given. 1 : Fame trap 2 : Closure peripheral layer 5 : Retention plates 6 : Boring 7 : Spark erosion electrode.
