Abstract
An apparatus for the manufacture of a contoured insole construction includes a driving mechanism for moving a sheet of continuous material along a cutting path by a pair of closely spaced apart form factor rollers and then using them to simultaneously deform the sheet of continuous material and to guide a flexible continuous knife belt disposed within the cutting path into cutting engagement with the sheet along a desired contour formed by the pair of rollers to separate a contoured single piece footwear construction from the sheet of continuous material.
