A cutting-edge VERTEX multifilament spinning line will be available for demonstration runs and customer trials at SML’s Technology Centre from the third quarter of 2025. This new spinning line is specially designed to efficiently manufacture partially oriented yarn (POY) or fully drawn (FDY) yarn at low titres in higher volumes.  
 

Key characteristics of the VERTEX concept are the optimisation for PET, the ability to manufacture a wide range of different yarn types, qualities and colours, as well as the line’s expandability. Beside PET, VERTEX lines process PP and PA at the same high-quality levels. “The VERTEX series is the perfect addition to our top-selling Austrofil MT/HT multifilament spinning lines,” Thomas Pucher, Product Manager at SML, states. Typical end products are fine yarns for textile applications, outdoor clothing, home textiles, carpet piles, and upholstery.  
 

Focused on yarns from 50 – 1,200 den 
A clear strength of the VERTEX series lies in the titre range between 50 to 1,200 den at an maximum output capacity of up to 270 kg/h. “Even at high speeds the VERTEX concept guarantees premium quality at low titres. Generally, this is enabled by the precise interaction of key components, with the sophisticated yarn path making a particular contribution,” Thomas Pucher explains. The simple start-up process with ramp-up function contributes to the efficiency of the VERTEX lines as well.   

Configuration options and extendability 
The VERTEX concept stands for exceptional customisability and a high degree of flexibility in production: Two separate spinning heads enable the simultaneous manufacturing of two different products. Spinning positions can be adjusted flexibly. The VERTEX line can be equipped with one or two extruders of different types and performance parameters, exactly tailored to the requirements of each individual customer. Thanks to its modular design, the line can be easily extended to increase capacity, scaling from 24 ends up to 32, 48, or even 64 ends as needed. 

In terms of winding, three different types of winders are available: Depending on whether the manufacturer's focus is on high-speed winding, high flexibility or on a simple winder design.
