Autoconer packages for Twisting and Assembly Winding. 4 >1 >2 The Twisting, process places extremely high and quite specific demands on the unwinding properties of the cross-wound yarn packages. This is true of the twisting process itself and of assembly winding, a process which in certain cases precedes twisting. In both processes, 2 yarn packages are used for feeding the machines and have to be unwound with equal yarn tension. Thanks to the Autotense FX Yarn Tension Regulating System, the Autoconer 338 produces yarn packages with extremely uniform structure and density. Central setting of the winding parameters ensures reproducibility of the winding parameters for all packages. There are no variations in yarn tension when the packages are unwound in twisting or assembly winding. The plied yarns have an absolutely even structure. >1 The Length Measuring and Full Diameter Computation System of the Autoconer 338 ensures that the length of the yarn in the packages produced is exactly measured and the length is the same in all packages or the packages are all of the same diameter. This is a further precondition for the economical production of high-quality plied yarns. High-precision yarn length measuring is possible with the Ecopack FX system (optional extra). Not infrequently, plied yarns have to be produced of wool or elastic single yarns. Up to now, yarn packages of such yarns could not be fed directly to two-for-one twisting machines, as placing the packages on top of one another in the supply creel was impossible because of the bulge-out of the package flanks. This problem has been solved with the integrated Variopack FX system on the Schlafhorst Autoconer. Bulging-out of he package flanks is reduced to a minimum. Yarn packages produced with Variopack FX can without problem be directly fed to two-for-one twisting machines. The Autoconer 338 produces packages with all the formats used in twisting, with a yarn-guide traverse from 4" to 6". Regular and orderly laying of the yarn onto the package is ensured by the various types of yarn guide drums. For winding wool or wool blend yarns intended for twisting, the use of the Thermosplicer is recommended. >2 Whether for direct feeding to twisting machines or for feeding to assembly winders, the Autoconer yarn packages offer ideal conditions for cost efficient processing and top-quality results in the textile production chain.
Autoconer packages for Warping and Weaving. In sectional and beam warping as well as weaving, good unwinding performance of the packages for smooth unwinding of the yarn is decisive for the achievement of high quality and cost-efficiency. Packages must allow highest weft insertion speeds and cope with the enormous alternating stresses due to changing acceleration on the weaving machine. Processing a multitude of packages simultaneously in sectional and beam warping requires extreme uniformity of the yarn lengths in the packages from which the yarn is taken. Stoppages due to yarn breaks or entangled yarns or yarn layers, or other faults disturbing the warping or weaving process, cause enormous production losses. This is why the packages for use in the production phases downstream of winding are required to satisfy the following criteria: absolutely uniform structure and density with large package diameters, orderly laying of the yarn, safe yarn-like spliced joints and precisely measured equal length of the yarn on all packages used in a process. Thanks to the expertise in winding technology of Schlafhorst, the Autoconer 338 is optimally equipped for the production of packages satisfying all these requirements. The Autotense FX Yarn Tension Regulating System ensures a constant level of yarn tension, and hence, uniform package structure and density. The Propack FX Package Cradle Anti-patterning System improves the package structure still further by eliminating critical patterning zones. Even at the highest weft insertion speeds, as on air-jet weaving machines, there is no sloughing-off of yarn layers. Thanks to Propack FX, the package diameters are not limited by critical patterning zones on the package. The yarn is safely and orderly laid onto the package, even when yarns with critical, smooth structures are wound, due to the smooth start-up and acceleration of the package and precise guiding of the yarn through the yarn-guide drum grooves. The modular splicer system of the Autoconer 338 offers splicing options for efficiently splicing all types of materials and producing spliced joints that safely withstand the alternating stresses to which the yarn is subjected on the weaving machine. In the doffing process, the doffer places the yarn bottom reserve onto the package tube and lays the tip tail onto the package, so that the transfer of the yarn from one package to the next in weaving presents no problem. The operators can fasten the yarn ends of the packages together easily and safely. Highest-precision yarn length measuring with the Ecopack system guarantees that in warping all the packages on the warping creel run out at the same time, thus reducing the amount of waste yarn significantly. In warping and in weaving, these performance characteristics of the Autoconer 338 are a guarantee for highest levels of cost-efficiency and productivity. 5
