                    - For all elastic yarns on flat knitting machines
 - Yarn tension adjusting, electronic feed wheel with yarn sensor
 - The yarn sensor provides for constant tension over the entire yarn speed range
 - Finer appearance to fabric: The Elastane pulls the stitches together, making the fabric gauge look finer
 - Even knit structure, uniform appearance to fabric
 - Softer handle to fabric, even with high-twist and hard yarns
 - Collars and cuffs keep their shape

                    - Integrated yarn take-up system for elastic and non-elastic yarns
 - With both directions exactly the same yarn tension
 - Higher machine speeds
 - Increased stability of the yarn tension by adjusting in the millisecond range.
 - The large yarn tensioning path up to 600 mm covers the entire range of applications
 - The individual devices can be variably grouped.
