WAXING CONDITIONS IN THE OPEN-END ROTORSPINN PROCESS:
1) The waxing device applies the wax in minuscule particles on
the yarn, obtaining an optimal friction coefficient with the lowest wax
take-up.
2) The wax should not separate into layers nor should it spread
onto the waxing device.
3) The wax must have a smooth surface without trapping any air.
4) The wax roll should be replaced when the thickness is about
5 mm.
