Pattern design, grading and marking optimizing system for garment industries

Claim 1

Pattern design, grading and marker op­timizing system in garment industries, of the type com­prising a first module including a computer processing central unit, a digitizer, a direct access memory unit, a sequential access memory unit, complete or shared, a com­puter console, controllers and interfaces for peripherals, and eventually a data output peripheral member, the first module electronically codifying the information relating to a two-dimension outline and applies to it a grading or scaling, the informations about treatments and operations performed on the patterns being permanently stored; a second module including a computer processing central unit, a digitizer, a direct access memory unit, a sequen­tial access memory unit and a computer console, this second module locating the outlines which are stored in the direct access memory unit onto a band of material, such that the outlines cover the greatest possible surface of the material; and a third module including a computer processing central unit, a first controller for drives and a second controller for the console, interfaces for the said controllers and a drawing device provided with a table upon which the material to be scored is placed, and the corresponding drawing head and means for operating it, characterized by the fact that the first module digitizer comprises a table including a two-dimension grating con­nected to a codifying network for the several magnetic field intensities corresponding to every one junction of the grating, and a locating device consisting of a pencil-­like body including s metallic core, an induction coil surrounding the core to generate a magnetic field the in­tensity of which is picked-up at the grating junction in contact with the outer end of the metallic core, and a contact switch which closes merely under contact to ac­tivate the network, the table being provided with a digitization menu comprising a plurality of icons adapted to be selected by means of the locating pencil, each said icons corresponding to program options permitting to progressively define an outline on the computer console of the first module.
