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.
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. 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.
