ElEctronic conE winding machinEGrooved drum for continuous bulking and shrinkagE

ElEctronic conE winding machinE mod. Va

designed for continuous bulking and shrinkage of HB and acrylic yarns, also blended with elastomers and for the bulking of

woolen yarns

Winding speed from 250 to 1000 m/minute, shrinking rate from 0 to 30%

- the packages can be prepared with constant density for dyeing or waxed and be ready for knitting or any other application

- shrinking chamber with 4 spindles

- adjustable temperature and processing time of the yarn inside the shrinking chamber

- shrinking chamber with circulation of forced air heated by electric resistances

- shrinking and bulking with saturated steam coming from the external boiler (optional)

- count range from 3 to 50 Nm

- temperature of the shrinking chamber up to 130° C
