ABSTRACT:
A machine or apparatus for producing ice cubes comprising flexible membranes which are flexed into and out of thermal contact with a refrigerated evaporator core upon which conductive areas define discrete freezing sites which determine the location on the flexible membrane where the ice cubes are formed. The ice cubes are removed by flexing the flexible membrane. The flexing of the flexible membranes into and out of contact with the evaporator core may be accomplished with a fluid source which applies fluid to and removes fluid from collapsible spaces between the evaporator core and the membranes.
