IX. The Point Tie-up in Three Sections.

This method of tying-up Jacquard looms shows the point tie-up applied

to the three-section arrangement, on the same principle as the

straight-through in paragraph VIII.

[Illustration: Fig. LXII.]

Fig. LXII. shows the comber-board divided into three distinct sections,

marked _I._, _II._ and _III._ For explanation, take a 300 machine;

allow 100 needles and hooks for each section, distributed as follows:

Section I., 1 to 100; Section II., 101 to 200; Section III., 201 to

300. Each section contains 200 warp-threads; and the complete division

of three sections, 600 threads. The threading of three sections,

illustrated in Fig. LX., is applied to the present tie-up, as follows:

1st end, from section I., attached to No. 1 harness-cord.
