Sole-cut′ting ma-chine′.
One in which soleshaped pieces are cut from the side or from strips of leather.
The ordinary hand-cutters have dies the shape of the sole, driven by a mallet.
Or a sheet-metal pattern is laid on the leather, and its edge followed by a knife.
In machines, several plans are adopted.
One has a vertically moving sole-shaped die, which is brought down upon the leather fed upon a table beneath.
Or a roller has projecting blades shaped alternately like the respective sides of the sole.
The strip is passed along the bed, beneath the roller, and issues as soles and waste scraps.

Another sole-cutting machine is one in which the leather and the metallic pattern are clamped to a circular revolving table.
The knife is supported on swivelled arms and follows the edge of the pattern, being actuated by a cam and a toothed foot-lever, which also raises a weight to perform the return motion.
See also sole-rounding machine.
