Optimisation means working on details
Spinning, splicing, winding – the optimal coordination of these processes results in high-quality end products. Saurer creates the basis for this with proven technology and constant innovation.
In terms of the structure and functionality of yarns, rapidly changing trends in fashion present spinning mills with more and more varied requirements. Here ring spinning scores points with its flexibility. Spinning and winding can be optimally coordinated with each other in the combination of the Z 72XL ring spinning machine and the Autoconer winding machine. Both are at the highest technological level – and are constantly being further developed.
In ring spinning, yarn, splice and package quality are the key factors influencing the characteristics of the final article in the areas outerwear, home textiles and sportswear, and are responsible for an efficient production process. More specifically: what the drafting system achieves during spinning and what the splicer and drum achieve during winding – these small components have a decisive effect.
Optimisations in ring spinning
The drafting systems of the Saurer short-staple ring-spinning machines ensure the greatest possible flexibility in every respect during spinning.
Depending on the customer requirement, the mechanical weighting arm of the PK 2600 series can be equipped with various cots and top apron cradles. It impresses with consistent yarn quality, highly flexible settings, easy handling, no loss of pressure due to leaks, and has long set the benchmark in this area.
Optimisations in the splicing process
During splicing, it is important that the yarn ends are connected reliably and in a visually unobtrusive manner. After intensive air-flow studies, Saurer developed a new splicing prism. The result: higher splicing strength with a lower variation range, a shorter, visually unobtrusive splice zone and coverage of a wider yarn spectrum. This increases process reliability in further processing and improves the quality of knitted and woven fabrics.
Optimisations in package build-up
For the package build, Saurer engineers have also discovered the optimisation potential in detail. Knowing well that nuances are critical for yarn displacement, they increased the traversing width of a drum from 150 mm to 154 mm. Result: more yarn length at the same diameter, 1–2 % more content per package. For customers this means: more weight per packing unit and therefore lower transport costs, longer operational run-time of the packages in further processing and less handling, because fewer packages need to be reloaded.
„Our spinning and winding components make the qualitative difference.“
Well-proven technology plus innovation, particularly for the key components: with this combination, Saurer creates noticeable advantages for the overall process – in the interest of its customers.
Key components in the ring spinning process and for winding
- Weighting arm of the PK 2600 series: constant yarn quality
- SmartSplicer with innovative prism: strong spliced joint with good appearance
- Drum with larger traversing width: more yarn length at the same package diameter
