VORRICHTUNG ZUM ERWAERMEN EINES STRANGS AUS ELEKTRISCH LEITFAEHIGEM MATERIAL.

摘要

The pairs of electrodes (30,31) are coupled to a high frequency generator (23) to provide the heating effect. The elecrodes form capacitor plates, electrically insulated from the strip material. Smaller plates (32) are positioned on the sides of the strip where there are no main and are similarly linked to the generator. The overall heating effect from the different paris of electrodes an even heating pattern without forming any localised discontinuities, especially for heat setting materials.
