Winding Options
- The standard supply is complete with manual winder with either parallel or conical output package. This choice is particularly suitable for making packages for dyeing.
- The S300 can also be supplied equipped to work with a modern automatic winding machines such as the Schlafhorst 338. In this case the winder is not included in the supply of the Macart Spinning Systems S300. This choice is particularly suitable when using producer dyed fibre.
