The cropped cloth is now taken to the clamping machine, and placed
on the floor on the left of the machine illustrated in Fig. 43,
which represents the type made by Messrs. Charles Parker, Sons &, Co.,
Dundee. The cloth is passed below a roller near to the floor, then
upwards and over the middle roller, backwards to be passed under and
over the roller on the left, and then forwards to the nip of the
pulling rollers, the bottom one of which is driven positively by
means of a belt on the pulleys shown. While the cloth is pulled
rapidly through this machine, two lines of fine jets spray water on
to the two sides of the fabric to prepare it for subsequent processes
in which heat is generated by the nature of the finishing process.
At other times, or rather in other machines, the water is
distributed on the two sides of the cloth by means of two rapidly
rotating brushes which flick the water from two rollers rotating in
a tank of water at a fixed level. In both cases, both sides of the
fabric are "damped," as it is termed, simultaneously. The damped
fabric is then allowed to lie for several hours to condition, that is,
to enable the moisture to spread, and then it is taken to the
calender.

The calenders for jute almost invariably contain five different
rollers, or "bowls," as they are usually termed; one of these bowls,
the smallest diameter one, is often heated with steam. A five-bowl
calender is shown on the extreme right in Fig. 41, and in the
background, while a complete illustration of a modern 5-bowl calender,
with full equipment, and made by Messrs. Urquhart, Lindsay & Co., Ltd.,
Dundee, appears in Fig. 44.

The cloth is placed on the floor between the two distinct parts of
the calender, threaded amongst the tension rails near the bottom
roller or bowl, and then passed over two or more of the bowls
according to the type of finish desired. For calender finish, the
bowls flatten the cloth by pressing out the threads and picks, so
that all the interstices which appear in most cloths as they leave
the loom, and which are exa
