Leath′er-split′ting ma-chine′.
An apparatus for dividing leather into two or more layers.
Split leather is much used in making boots and shoes of cheap quality.
The advantage in using the splittingmachine is that the quantity of leather surface is doubled.
By splitting so as to preserve the
grain side, one sheet of very fair leather may be obtained, while the other (
skiving) is fit for trunk-covers, etc. The machine consists essentially of one or more rollers, which draw the leather against the edge of a horizontally arranged long knife, by which it is divided, one half passing above and the other below the knife.
In
Stearns's machine (
Fig. 2883), the leather is drawn forward by the tooth
e on the carrying cylinder
C, passes between the roller
O and presser-bar
E, and after being split by the adjustable knife
M is drawn between the carrying cylinder and the roller
S, in order to compress and smooth it; the amount of pressure being governed by the treadle and levers
T T T.
In
Marden's machine (
Fig. 2884), the leather is drawn to the knife
P between the rollers
G J, the latter gears loosely with both the rolls
G L, and its bearings are elongated vertically, that it may rise and fall to admit leather of varying thickness.

Fig. 2885, the knife
S reciprocates longitudinally, the cylinder is adjustable, and the leather is held down by a foot on the presser-bar

In another machine, the leather is split by an endless, knife-edged, steel band, sharpened by an emery-wheel while running.
