    • The present invention relates to a method of designing and cutting-out the leather for shoes. The paper pattern is firstly folded along its back central line and placed vertically, a perpendicular dotted line is drawn downwards from the upper endpoint of the back central line, the point where the dotted line is departed from the back central line is used as the starting point, and the lower endpoint of the back central line is used as the finishing point, the arc between the starting point and the finishing point is divided equally into sections, and a perpendicular positioning line which is perpendicular to the dotted line is drawn from the dividing point on the dotted line, those parts below the positioning line are rotated around the dividing point, until the next dividing point falls upon the dotted line, the overlapped parts produced during the process are cut away, all the arc sections are so processed until the finishing point falls upon the dotted line, the required design can thus be obtained by unfolding the paper pattern, finally the shoe leather can be cut out according to the obtained paper.
    • 本发明涉及一种设计和切割鞋用皮革的方法。 纸张图案首先沿其后中心线折叠并垂直放置,垂直虚线从后中心线的上端向下拉,虚线离开中心线的点作为起始点 将后中心线的下端作为终点,将起点与终点之间的圆弧均匀地划分成几段,垂直于虚线的垂直定位线从 在点划线上的分割点,定位线下方的那些部分围绕分割点旋转,直到下一个分割点落在虚线上,在该过程中产生的重叠部分被切除,所有弧形部分被如此处理直到 完成点落在虚线上,因此可以通过展开纸图案获得所需的设计,最后可以将皮革切割成accor 对所获得的纸张。
