Spandex yarn feeder model KSE 22 series, which is designed for Rewinder machines. In this model, for each position of Rewinder machines, a separate motor and a sensor are provided for feeding and controlling Spandex yarn (Lycra), which are connected to the Rewinder cutter by means of a control circuit. It is noteworthy that by installing the spandex yarn feeder on Rewinder machines, it is possible to combine the stretched yarn with the spandex yarn with the help of Jet Intermingel, just like air covering machines.
