    • A cutting blade system for cutting sheet material into pieces of generally the same contour but of different sizes, especially useful in the manufacture of apparel for cutting cloth into pieces to be sewn together into garments. The system involves a set of primary cutting blade segments common to all sizes of a piece of given contour or pattern to be cut out of the sheet material and a set of auxiliary cutting blade segments additive to (or subtractive from) the primary segments to constitute cutting blade assemblies of different sizes in the stated contour or pattern. The segments are made of steel rule die stock, are releasably held together in assembly, and assemblies of segments in various patterns are utilized in a hydraulic press for diecutting through one or more layers of material in the press. The press may have an electromagnetic head for magnetically gripping the assemblies for the cutting operation, and for quickly releasing them after the cutting operation, whereupon the assemblies may be disassembled and the primary segments reassembled with auxiliary segments in a different size.
    • 一种切割刀片系统,用于将片材切割成大致相同轮廓但具有不同尺寸的片,特别适用于制造用于将衣服切成衣服的衣物的衣服的制造。 该系统涉及一组主要的切割刀片段,所述主要切割刀片段对于要从片材切割出的给定轮廓或图案的所有尺寸是共同的,以及一组辅助切割刀片段被添加到(或减去)主要部分以构成 在规定的轮廓或图案中切割不同尺寸的刀片组件。 这些段由钢制模具坯料制成,在组装中可释放地保持在一起,并且用于各种图案的段的组件用于液压机中,用于通过压机中的一层或多层材料进行模切。 压力机可以具有用于磁力地夹持用于切割操作的组件的电磁头,并且用于在切割操作之后快速释放它们,从而可以拆卸组件,并且主段重新组装成具有不同尺寸的辅助段。
