An enclosure having a back wall which is made of a net-like material and unto which photo prints can be placed. A front part of the enclosure has at least one source of hot air which is directed to the back wall and switches which turn on and off the source of hot air and control the speed of the air.

A film dryer is provided primarily for use in the graphic arts in which relatively large sheets of film must be processed and dried. A part of input rollers is of sufficiently hard rubber as to squeegee off most of the surface moisture which drops into a drip pan where it may be emptied. Subsequent guide rollers are of short axial extent and spaced apart. Air jets are slightly warmed and blow generally toward one another and against the surface of the film, and back toward the entrance, whereby to carry moisture back into the area of the drip tray for collection. O-rings or other resilient guides are positioned over suitable supporting structure to prevent the film from wrapping up about the various rollers.

In a photocopying apparatus having a device for liquid developing a copy and of the type in which the copy is guided over a heating plate while being passed through a sealed chamber, one or more endless belts, preferably of velvet or fur, moved around two rollers are provided to transport the copy and also to urge the copy against the heating plate.
摘要:
A heating device is provided comprising a rotary transportation roller and pre-heated powder or granular bodies arranged and disposed around the periphery of said roller so that when a sheet-like, object to be processed is transported by said roller, said powder or granular bodies make direct contact with said object so as to heat the same.

A drier for drying copying paper in a liquid development type electrophotography apparatus includes a pair of squeegee rollers, and a pair of drier rollers provided next to the squeegee rollers. The peripheral surface of at least one of the drier rollers consists of a liquid-absorbing material. Air is evacuated from within a perforated endless belt to suck paper thereagainst for purposes of transportation. This air is moved past an exposure lamp where the air is heated and dried. The air is then blown against the liquid absorbing material and against copying paper passing therethrough.
摘要:
Method for developing and desensitizing lithographic plates having latent images in the form of a polymer coating of varying solubilities in differing areas by dispersing a solvent or desensitizer onto the plate, drying the plate, removing dissolved impurities from the solvent in situ, preferably by distilling the solvent, and returning the purified solvent to a reservoir for re-use.
摘要:
A flow of drying air in the direction of movement of and under successive individual sheets is provided as they leave development means after exposure in a copymaking machine and from which the exposed sheets are received and free liquid removed before the sheets are engaged by the air. The arrangement is such that the sheets are floated to a copy sheet receptacle.
摘要:
Hot air from the light source chamber is forced into a housing having an air inlet and an air outlet in close proximity to the exposed photosensitive paper. A heat radiation source is mounted in the outlet in the path of the air. Guide plates are mounted in the housing in the airstream from the inlet to change the air flow direction approximately 90*. Both the size of the guide plates and the extent to which they extend into the airstream are successively increased in accordance with the distance of the plates from the air inlet.
