Comber-boards made in Strips and Adjusted afterwards in a Frame.

By these comber-boards which are used to a great advantage on narrow loom work up to 36 inch fabrics, we can change the texture for the fabric; for the strips composing the comber-board may be drawn apart, thus changing the higher texture to lower; whereas in a solid comber-board this could only be done by re-tying the harness or changing the number of needles used in the machine. To give a clear understanding Figs. [XVIII.], [XIX.], [XX.] are needed.

[Fig. XVIII.] represents an 8-row deep comber-board, a, b, c, d, composed of 10 strips which are set close together. By examining each strip 5 cross-rows of holes will be found, making the whole number of holes 400.

Suppose the comber-board as represented in [Fig. XVIII.] is intended for a texture of 100 ends per inch; this will give for the width of the fabric (i, k, to l, m,) 4 inches.

Fig. XIX.

Fig. XVIII.

In [Fig. XIX.] the comber-board is arranged for a texture of half as many ends, or 50 holes per inch, and the 10 strips are arranged accordingly; the empty places between the strips are of same size as the strips themselves, and the fabric design below the comber-board is arranged to correspond.

Fig. XX.

[Fig. XX.] illustrates the sectional cut of the comber-board used in drawings, Figs.[ XVIII.] and [XIX.], and the letters indicating the different parts of these figures which correspond.
