 Total sales of machines for cutting cloth based on Gerber's patented inventions are in the multiple billions of dollars.Within two years, Gerber introduced the first numerically controlled machines for sewing (the GSM-70) and producing pattern layouts, known as "markers" (the MP-26).Ultimately, his company would develop computer-controlled systems for the designing, digitizing, grading, and prototyping of apparel patterns, and an integrated system that included fabric spreaders, parts-moving systems, concept design, and product data management.
