Abstract (en)

A woven or spiral link papermaking fabric (1) is passed through an oven (11) wherein at least one side is subjected to microwave radiation from a microwave radiation emitting device (13) which is powered by a magnetron (14) which is adapted to operate at a frequency of from 100MHz to 300GHz with impedance mismatch and frequency offset between the magnetron (14) and emitting device (13) being controlled to prevent a thermal runaway. The fabric may be of microwave absorbent fibres or yarns or of fibres or yarns including a microwave absorbent additive such as titania. <IMAGE>
