Curved Gates in Optical Printers

In certain types of optical motion picture printers, it is desirable for the film, in its printing position, to be curved along its length. With certain pull-downs, for example, it is almost essential that a curved gate be used; and in some cases it is possible, by using curved gates, to dispense with pressure pads and thus avoid the difficulties attendant upon accumulated dirt, grease, and emulsion.
