the piece is beamed, it is automatically moved between two huge
rollers, and hydraulic pressure applied. Four narrow pieces are
shown in Fig. 45 on the pin, and between the two rollers. There are
other four narrow pieces, already beamed on another pin, in the
beaming position, and there is still another pin at the delivery
side with a similar number of cloths ready for being stripped. The
three pins are arranged thus o deg.o, and since all three are
moved simultaneously, when the mangling operation is finished, each
roller or pin is moved through 120 deg.. Thus, the stripped pin will be
placed in the beaming position, the beamed pin carried into the
mangling position, and the pin with the mangled cloth taken to the
stripping position.
While the operation of mangling is proceeding, the rollers move
first in one direction and then in the other direction, and this
change of direction is accomplished automatically by mechanism
situated between the accumulator and the helical-toothed gearing
seen at the far end of the mangle. And while this mangling is taking
place, the operatives are beaming a fresh set, while the previously
mangles pieces are being stripped by the plaiting-down apparatus
which deposits the cloth in folds. This operation is also known as
"cuttling" or "faking." It will be, understood that a wide mangle,
such as that illustrated in Fig. 45. is constructed specially for
treating wide fabrics, and narrow fabrics are mangled on it simply
because circumstances and change of trade from time to time demand it.

The high structure on the left is the accumulator, the manipulation
of this and the number of wide weights which are ingeniously brought
into action to act on the plunger determine the pressure which is
applied to the fabrics between the bowls or rollers.
Cloths both from the calender and the mangle now pass through a
measuring machine, the clock of which records the length passed
through. There are usually two hands and two circles of numbers on
the clock face; one hand registers the units up to 10 on one circle
of numbers, while the slower-moving hand registers 10, 20, 30, up to
100. The measuring roller in these machines is usually one yard in
circumference.
If the cloth in process of being finished is for use as the backing
or foundation of linoleum, it is invariably wound on
