Take up solutions With the further development of downstream processes, the requirements for the DTY package constantly increasing. The best-possible package formation and the related unwinding performance are decisive criteria for effi cient manufacturing with up-to-date technology. As standard, the eAFK is equipped with ATT (Advanced Take-up Technology), the latest technology for advanced density controlled package formation, in conjunction with an automatic doffi ng unit. ATT – Advanced Take up Technology The quantum leap in package building technology comes with a single-position drive solution, fewer mechanical components and computer-control of every single stroke throughout the package formation, providing signifi cant benefi ts for the manufacturer and for the product itself. Furthermore, ATT allows for special solutions, such as unique fl exibility in package geometry or quality indicating marking of packages, which have – until now – been impossible using mechanical take-up units. The individual position drives in process and maintenance increase the fl exibility during production and prevent unnecessary machine downtimes. A signifi cant lower noise level and a reduced number of mechanical parts, easy maintenance and improved accessibility round off the mechanical improvements achieved by ATT. Another highlight is the control of yarn tension during winding. In detail, this means the yarn tension profi le during winding cycle can be preselected in order to • actively control the decrease in winding tension • gradually lower the decrease in winding tension even down to a constant winding tension • higher package weight • even package density • prevention of yarn damage by reduced initial winding tension • unique features for winding dye packages A further feature is the choice of various take-up programs with an individual calculation of each stroke for even yarn distribution over the entire width of the package as well as uniform pressure distribution on the tube. 16 eAFK – Oerlikon Barmag
IAD – Individual Automatic Doffer The further-improved individual automatic doffer of the eAFK is the culmination of Oerlikon Barmag’s experience in automatic doffi ng. Reliable doffi ng performance to ensure the highestpossible machine effi ciency is the result of a sturdy take-up section in low-vibration design combined with Oerlikon Barmag’s CPC (contact pressure control) bobbin lever system. Adjustable for different package densities, it allows in conjunction with the Oerlikon Barmag TUP (Take-up Processor) - the best-possible package formation with excellent take-off performance. During the doffi ng procedure, waste injector systems transport waste yarn into easily accessible bins located on the creel side of the machine. Apart from the considerably reduced noise level due to use of the ATT system in the take-up section, the basic functionality of the IAD is the production of packages of uniformly-metered length. Two parking positions, in conjunction with one further full package in production, allow unattended operation for longer periods of time, depending on yarn titer. The eAFK take-up solution with ATT and IAD provides • Positions: up to 288 pos • CPC bobbin lever system • Winding of taper-ended packages with nominal taper angles of 65°- 90° • Max. package diameter - 250 mm • Basic (max.) traverse stroke length - 250 mm (273 mm) • Max. double strokes per minute ≤800 • Package formation • Traverse drive with ribbon breaking unit as well as with scattering system variable for highest process speeds • Automatic doffi ng • Two parking positions Take up Package formation Package shape Taper angle Density control Double strokes ATT +++ +++ ++ +++ ≤800 ++ Maintenance eAFK – Oerlikon Barmag 17
