Abstract: 1335434 Holding flexible media in contact CUTLER-HAMMER Inc 19 April 1971 [13 April 1970 15 June 1970 11 Feb 1971] 27200/71 Heading G2A A method of holding adjacent surfaces of two superimposed flexible ribbon-like media e.g. a master film and an unexposed photographic emulsion, in contact comprises supporting the first medium and pressing the second medium against the first by fluid having a high static pressure and allowing the fluid to escape across the side edges of the media through constrictions so that the static pressure adjacent the side edges is lowered and enables fluid trapped between the adjacent faces of the media to escape. In Fig. 2 an embodiment of apparatus for carrying out the above method is shown in a contact printer and comprises a platen 23 for supporting the master film and a housing 25 having side walls 43,44 which together, with the platen 23, form the constrictions. The cavity between the housing and the unexposed film is injected with air to give a transverse static air pressure profile as shown in Fig.10, thus forcing the films into contact. The platen 23 may be microporous and may have air forced therethrough to support the master film on an air cushion or alternatively Fig. 5 (not shown) the platen may have the same construction as that shown for the housing in Fig.2. In the contact printer of Fig.1 (not shown) the films are maintained planar during exposure and the static air pressure is applied to them in the exposure zone. To further prevent the entrapment of air between the films the housing may be shaped to a point at one end so that the pressure is gradually applied to the films from the centre outwards as they move into the exposure zone. In an alternative embodiment, Fig. 3, the contact printer comprises a light transparent cylinder housing a light source 52. Immediately adjacent the cylinder is a housing 55 into which air is directed from a source 56. This produces the static air pressure and forces the master film 50 radially outwardly into contact with the unexposed film 51, the latter being supported by an air cushion formed adjacent a microporous platen 57.
