Title:
METHOD FOR CUTTING EDGE LEATHER MATERIAL
Document Type and Number:
WIPO Patent Application WO/2021/077804
Kind Code:
A1
Abstract:
A method for cutting an edge leather material. The edge leather material (1) is an edge leather material (1) produced by cutting using a single crystal silicon rod, and the edge leather material (1) comprises: a rectangular bottom surface (11), an arc-shaped surface (12) opposite to the bottom surface (11), and a pair of end surfaces that are provided at two ends of the bottom surface (11) in the longitudinal direction, respectively. The junctions of the bottom surface (11) and the arc-shaped surface (12) are sharp corners (2), and a part of the arc-shaped surface (12) located between the sharp corners (2) at two sides of the edge leather material (1) is an arc-shaped protrusion (3). The cutting method comprises: cutting off the sharp corners (2) at the two sides and cutting off the arc-shaped protrusion (3). The sharp corners (2) at two sides are cut off along the thickness direction of the edge leather material (1), and the arc-shaped protrusion (3) is cut off along the width direction of the bottom surface (11) of the edge leather material (1). The cutting method may reduce the cutting time of the sharp corners (2) and the arc-shaped protrusion (3), and improve the cutting efficiency of the sharp corners (2) and the arc-shaped protrusion (3). Moreover, the method may reduce the slicing time and improve the slicing efficiency.
