The EFS 800 is an advancement based on the experience with the EFS 600 series.
The EFS 800 has been developed for single and double cylinder sock and hosiery machines as well as for body and large-diameter circular knitting machines. It serves the tension-controlled infeed of elastic and non-elastic yarns.
The yarn is driven off the bobbin and fed to the machine via a sensor which measures the yarn speed, on the basis of which it controls the feed speed. The yarn tension can be adjusted via keys at the device and read on the display as a setpoint or actual value. Furthermore, the yarn speed is shown.
