Abstract
The method involves controlling the spray jet of the sprayer of the spray cones of the sprayed coating material by limiting adjustable gas flow that is encircled circularly. Two independently adjustable gas flows are generated that emerge in different radial distances from the spraying cone axis and are set as a function of the workpiece areas that are to be coated. An independent claim is also included for sprayer for serial coating.

DESCRIPTION
The fhventfôb regies to a method of coating a workpiece and to an atomissr for senai coating of ^rkpieoos Ä oPtet onflces for afasstfeam bounding ifeespray cone according to the ptecharaoièdé^ claims. in particular, ;S relates to control of the shaping air of electrostatic rotary atomisers, as are convenifonsl: lor the sariiícoattog of workpieces such as lortexample vehicle bodies, it may however also reiste to other types of atomiser. The invention is stiitsbie for any desired boating materiéi invading weipaintapd coating powder. tin ^^^dëi'iei^i'Âëars (DE 480688(¾ which atomise tlfo coating material: by ih® action of a feel! ponyeripnaliy rotating at ewer to direct shaping air out of tee atomiser onto fe ænicaÎ outer beii an impetus in the direction of the workpiece to the coating particles released radiaiiy per se at the beii cup spray retease edge in addition to the efeetrsstatieforces, but also servos to shape the spray jeisrid partly also provides assistance during atomisation. The shaping air emerges iom a nrtg öf PMs Iihdhe end face of a shaping air ring arranged ät öté front end of the atomiser housing, The number, diamoter, shape: and dlfectkto of the bares may differ to optimise air speed, airquanëty and; spray jei width. The shaping air quantity desired in each case: following the spray jet width, is set as a parameter of the coating process and Is closed-loop controlled. instead of hams, annular gap-shaped outiét orifice arrangements may be provided for the shaping aif. In the case of a rotary atomiser knowmftem EE #92043, there is ptoyided, in addition tesam^yinner'-pan^yp^l^te actual shaping air, an outer annular gap which is supplied py; toe same compressed ër soufoe as foe inner annular pp. The gap width of one or both anrsfiiar gape is adlusfoPte.

Coafing application efficiency, which is defined as foe ratio between the material: released and foe mafonai deposited; is: greater with relatively smaii or narrow spray patterns than with wider spray patterns, resulting in signieantxxfepng and cost sayings, iri 114877 discloses atomisers with iritarchanpafeie Palis, which differ with regard to diameter, spray direction and shaping sir quantity and ere designed to fee selected depending on ifeo shape of foe object tefoe coated and foe pafof to fee PSsd etc,, fes exempte a large diameter Is small diameter for intemafsarfacss of vehicle bodies, in practice, dfo internai surfaces of vehicle bodies, such as for example door entry areas, door rebates, boot, engimt compartment and boot lid or banne! interiors etc. have not hitherto been coated using rotary atomisers, however, but instaac con van honily with spray grins, which dtemise foe coating material net fey romion but instead with ogmpresseiaSr, Those spt|y guns produce # lang, narrow:, relatively: highly concentrated spray pattern, which is better for coating tee relatively harrow surfaces of tee interior than: tee hitherto ©nveniionaliargeforeâ Sprey ; patterns ef round rot^mtomisers, However, in psrtteufai when performing interior costing using powder,, sal spray pus cause esatihg detects as foe result of powder sintering (so· dälfei §pit8ftp|<:.#sidb regula slsfoöratß ftőte cöfefes quality, application efeefeneyns also poorer with φ^
