Abstract
Sheet material is moved along its length from a supply to a take-up spool and the material is inspected as it is moved. A garment pattern image is projected on and is moved with the material. The operator determines where the material is to be cut either from the length accumulated on the take-up spool or from the image projected on the material, and if a flaw in the material is detected, the operator determines if the flaw should be removed by identifying the pattern part in the garment from the image projected on the material where the flaw will appear. If the flaw is to be removed, the operator cuts the flaw out and splices the cut ends of material together at splice marks in the image projected on the material. The spools loaded with sheet material with this procedure are loaded in a creel, and the ends of the sheets of material from the spools in the creel are aligned in a vertically stacked arrangement and moved to a cutting apparatus where the garment pattern is cut in the stacked sheets of material.
