摘要：
Drying rollers for use in the dryer section of an automatic X-ray or other film developing machine which incorporates a pair of tangentially contacting, thermoplastic, micro-porous rollers which form a nip therebetween to receive the developed film from the wash tank. The rollers serve to dry the film surface by absorbing the moisture into the roller pores by capillary action. The usual dryer section heater continuously dries the rollers as they are rotated in the dryer section when the film travels through the developing apparatus.
