Saw a type of dry-mount press I'd never seen before at my local recycled-goods place. It's definitely not a Seal, Inc. press, which is the only type I've seen until now. This one has a larger frame, and in addition to the heated platen and bed, there's an intermediate part with a plastic sheet held between two rods that goes between the platen and bed. The plastic is flexible but seem impervious. There's a large bolt in the middle of the frame to adjust the pressure, and two lights, one marked "HEAT", the other "AT TEMP", plus a temperature control. Does anyone know what type of press this is and how this works? This one seems to be in good working condition and not too much money.
