XRF330 Dual foil rewind for heat transfer materials

The XRF330 is a special dual rewind machine for heat transfer materials. It will only touch one side of the material. This is important when doing heat transfer as the print side must be protected from scratches. The machine interfaces to the Xeikon 300, 330, 3000 & 3300 press.
