Abstract
A method for automatically producing different sizes of a particular garment from a basic pattern, wherein the basic pattern is sampled and digitized and this information is entered into the memory of a computer. A reference measurement value is determined utilizing characteristic points of the basic pattern. This reference measurement value along with data provided in the computer relating to evolutions in width and in length of the different sizes are used to calculate reference measurement values for each size. This value along with the characteristic points of the basic pattern are used to produce a pattern of differing size from the basic pattern.
Claims8
A method for the automatic grading of articles, such as garment pieces of different size, said method comprising the steps of:
- (a) entering and storing first data in a first memory of a computer representing the evolutions in width and in length of selected sizes of a predetermined scale;
- (b) physically sampling and digitizing second data from a basic pattern and entering and storing said second data in a second memory of such computer, said second data used to form an image of the basic pattern provided with a plurality of characteristic points defining the outline of the basic pattern;
- (c) determining a reference measurement value located on an axis defined by two of said characteristic points of the basic pattern provided by the data in said second memory;
- (d) storing said reference measurement value in a third memory of said computer;
- (e) calculating the reference measurement value of each of the different sizes of the garment pieces from the information provided in said first and third memories, said calculating step conducted in said computer;
- and
- (f) calculating in said computer the characteristic points of each of the various sizes of the garment utilizing the reference measurement values of each size of the garment determined in step e) as well as the characteristic points of the basic pattern stored in said second memory thereby providing information from which an image outline of the various sizes of the basic pattern which can be produced, said characteristic points of each of the various sizes stored in a fourth memory.

- and
- (g) automatically cutting the various sizes according to the image outline determined by the calculation of the characteristic points for each size of the garment.
