For the purpose of giving a correct comprehension of the foregoing explanation of tying-up, but under a different arrangement, [Fig. XXXIX.] was designed for a 600 machine, having the same arrangement of the borders, viz.: point tie-up, using one-half division for each side; the centre a straight tie-up, but employing only one repeat. The following particulars will explain the entire procedure:

200 needles and hooks are used for borders, point tie-up, once through, equals 1/2 division for each border. [See letters B and on comber-board.]

Fig. XL.

400 needles and hooks are used for centre, straight tie-up, one repeat. [See letter C on comber-board.]

200 ends for each border,= 400 warp-threads.
200 ends for centre,= 400 warp-threads.
----
800 warp-threads.

In the ground plan of the fabric A is the centre; B, , B´´, B´´´, borders; C, , C´´, C´´´, corners.
