In this paper the beoding of a infinite plate cut by a finite number of cuts along one line is discussed. One of the cuts is infinite. Special attention is drawn to the fact that at given loads on cuts the bending in the end points of cuts is in general unbounded. In order to deal with these particularities, special forms of stress functions and conditions are found that have to be fulfilled by the load function on cuts to make the bending and its derivatives bounded everywhere on cuts.
