It will be seen on referring to the illustration that there are
three crushing rollers, one large central roller on the top and
situated between two lower but smaller rollers. Each roller has a
series of knobs projecting from a number of parallel rings. The
knobs are so arranged that they force themselves into the hard
layers of jute, and, in addition to this action, the heads of jute
have to bend partially round the larger roller as they are passing
between the rollers. This double action naturally aids in opening up
the material, and the machine, which is both novel and effective,
gives excellent results in practice. The degree of pressure provided
for the top roller may be varied to suit different conditions of heads
of jute by the number of weights which are shown clearly in the
highest part of the machine in the form of two sets of heavy discs.

The driving side, the feed cloth, and the delivery cloth in this
machine are placed similarly to the corresponding parts of the
machine illustrated in Fig. 8, a machine which also gives good
results in practice.

In both cases the large heads are delivered in such a condition that
the operatives can split them up into pieces of a suitable size
quite freely.

The men who bring in the bales from the store take up a position
near the end of the delivery cloth; they remove the heads of jute as
the latter approach the end of the table, and then pass them to the
batchers, who split them. The most suitable size of pieces are 2-1/2
