Abstract

A pressure roller for applying pressure to a sheet-like material passing between the pressure roller and an application roller for applying a layer of liquid to the material, as in the development of diazotype copies, comprises a plurality of relatively short constituent rollers connected to one another by connecting means which permit radial displacement of the adjacent constituent rollers relative to each other and wherein each constituent roller is urged toward the application roller by at least one resilient spring-like element. The pressure roller thus enables contact between it and the application roller with an even pressure, without significant sagging along its length, while allowing uneven areas of the sheet-like material to pass therebetween without affecting the force exerted over the entire nip between the rollers. Improved development of diazotype copies can thus be obtained.
