An old machine, made several years
ago for destroying railway tickets, has
been introduced on large scale to meet
the requirements of the West African
rubber merchants in the cutting up oil
raw rubber into shreds. BY this pro-
cess the moisture is exuded and the rub
Der can be PACKED into less space for
shipment. The machine consists OF
two sets of disks with very sharp eiges,
carried on wooden franc. These disks
are placed at suitable distances and
slightly intersect each other. Ao've
them is a wide -mouthed hopper. Each
set of disks, which are driven by hand,
with ordinary gear, revolves toward the
centre of the machine, and as the "a"
rubber is fed into the machine it is im-
mediatey grasped aud cut into shreds,
which are combed out underneath aud
discharged.
