3). While at D, the bale in the cell (called from its
construction a revolver) is partly lashed, the ties or ropes being put
into position. It is then rotated until it comes over the large rams,
where the bale is still more compressed and secured.
It must be admitted that this press provides for the greatest possible
economy of time, and for the largest output, for the capital employed,
which can be attained. The rams and the men are constantly in action,
and not a single moment is lost. For filling each box 78 seconds are
allowed, and there is ample time for the preliminary lashing.
[Illustration: COMPOUND HYDRAULIC PRESS. FIGS. 5 and 6.]
Figs. 5 and 6 show a modification of this press, designed to turn out
sixty bales per hour. It has only one set of long-stroke rams, with
three revolvers. The bale receives its preliminary lashing while in
the position, B (Fig. 6). Fifty-three seconds are available for
filling the box, and the same time for the preliminary lashing. It is
found, however, that three-quarters of a minute is sufficient for the
complete hooping of a bale.
[Illustration: COMPOUND HYDRAULIC PRESS. FIGS. 7 and 8.]
Figs. 7 and 8 show a similar press intended for jute pressing. This
has only one box, which is fixed, as the material has to be packed in
an orderly manner.
