    • A two-dimensional foil having slits that allow the foil to convert into a three-dimensional lathe by stretching out the lathe so that the slits form pockets or openings. The lathe is made of a foil that can have a plurality of individual slits formed in parallel spaced rows extending transversely from one end to the opposing end. The foil is expandable by extending the opposing ends of the foil in a lengthwise or widthwise direction, whereby the slits form an array of openings. The length, width, spacing, number of the cuts and the extent of staggering between the rows can be varied. The two-dimensional foil can be easily stored in the non-expandable position in a roll form, allowing inexpensive and easier handling and transportation.
    • 具有狭缝的二维箔片,其允许通过拉出车床将箔片转换成三维车床,使得狭缝形成袋或开口。 该车床由箔片制成,该箔片可以具有多个形成为平行间隔的行的单个狭缝,其横向从一端延伸到相对端。 通过在长度方向或宽度方向上延伸箔的相对端部来扩张箔,由此狭缝形成开口阵列。 切割的长度,宽度,间距,数量和行之间的交错程度可以变化。 二维箔可以容易地以卷状存储在不可扩张位置,从而便于操作和运输。
