Abstract: A method and apparatus for producing a graft for a patient consisting of foreign skin provided with openings and segments of a piece of the patient's original skin inserted into the openings are disclosed. A piece of the patient's original skin is cut into segments arranged at specific locations in a system of coordinates. A backing, carrying foreign skin, is also placed within the system of co-ordinates and openings are cut into the foreign skin at similarly defined locations. The segments of the patient's original skin are then placed by mechanical means into the openings of the foreign skin.
