Method for scanning sheet-type work material and cutting pattern pieces therefrom

Abstract

In a method for scanning and cutting sheet-type work material carried on a support surface, the work material is automatically scanned to determine a periphery thereof and to allow for the detection of any flaws within the periphery of the work material. The layout of a marker is then established on the work material and a nesting process for pattern pieces is begun. A first pattern piece is nested onto the work material and a subsequent pattern piece is also nested onto the work material while the first pattern piece is simultaneously cut therefrom. These steps are repeated until all of the pattern pieces are cut from the work material.

Description

technical field [0001] The present invention relates generally to cutting pattern blocks from process material, and more particularly to methods for simultaneously nesting and cutting said pattern blocks from process material. Background technique [0002] Patterns for making clothes or interior decoration are often used by those skilled in the related art, and the patterns will be referred to as marks in the present invention. When a pattern is to be cut out of leather or other animal hide, it is necessary to know the shape of the periphery of the leather and the location of the defective areas that the leather itself has. Thus, the layout or nesting of the pattern blocks on the leather, wherein the pattern blocks include the indicia, will change position and orientation from leather to leather depending on the shape of the leather and where the defects are located. Typically, this defect detection and nesting is done by hand, and once the markings are placed, the pattern ...

AI Technical Summary

Problems solved by technology

Scanning and nesting operations are time consuming, as are subsequent cutting operations

Also, there is a time lag between operations, or the scanning, nesting and cutting operations can be done on different machines
