    SUMMARY The present invention comprises an arrangement (110) for producing from an elongate metal starting material ("A") an elongate product ("B") processed into a dimension reduction, such as a wire. This takes place during the utilization of a number of, in series-oriented, starting material coating and / or processing stations (11, 12). A first, an elongate, station (11) is adapted to have the starting material ("A") coated with a lubricant adapted for dimension reduction ("c") and a second, station downstream of said first station oriented station ( 12) is adapted to have the dimension of said starting material coated with the lubricant reduced to said product. Said first station (11) is adapted to allow the starting material to pass through the first station (11) centrally, or at least substantially centrally, and that this first station is in addition adapted to be coordinated with a charging electrode (31, 32). adapted for an electrostatic charge of the particles of the lubricant in relation to said starting material ("A"). The invention provides that said charging electrode or electrodes (31, 32) are to be distributed along one (upper) half (11a) of the first station and that said lubricating means ("c") is to be adapted to be supplied to one half (11a) of said elongate first station. via a longitudinal gap (35) oriented there, to form a particle curtain (35a) along and around the starting material ("A"). It is proposed that Figure 2 be attached to the summary at the time of publication.

The recycling to the cyclone unit 23 'functions both as a cyclone separator andstorage containers, without any moving parts. (Figure 6).Only unused lubricants ("c") may be reused, wherefor the need for sieves, mills, etc. is deleted.9. Discharge electrode (s) can be used in a suitable place within a return line38, 38a, in order to avoid the accumulation and "hanging" of lubricatingpart.
    Figure 6 illustrates a cyclone unit in the form of a combined cyclone separator 23 'and a storage container 23 where the channel or conduit 38a, via an ejector (not shown)(40), transports the excess material ("c") into the upper part of the cyclone separator 23 'forto accumulate within the lower part 23 "of the cyclone separator and where a pipe 61 is fittedto regulate the upper level of the lubricant ("c") and at low level to create an automaticfilling from the storage container 23 via the tube 61. The tube 61 is enclosed by a101520pad cone 61a where air is to pass a slot 61b located over the narrower part of the cone61a '.
    The length of the slot 35 should connect to 30-50%, such as about 40%, of the station11 total length or the distance between the pull rings 51, 52.
    The invention is of course not limited to the embodiment given above as an example.but can undergo modifications within the framework of the idea ofillustrated in the appended claims.
    Special consideration should be given to the fact that each unit and / or circuit shown can be combined with eachother displayed unit and / or circuit within the framework of being able to achieve the desired technicalfeature.
