FIG. 66.
In the Norwich arrangement, the machine is placed so that the cards come over the head of the weaver or over the beam, and the short rows of 8 in the hooks correspond with the short rows of 8 in the cumber board, and thus the harness is kept straight.
The cumber board is a frame containing "slips"—pieces of wood with holes bored in rows; in a 400 machine, rows of 8; in a 600, rows of 12. Through these the leashes are passed, and the warp ends almost always drawn in straight draft through the mail eyes. Jacquard patterns are generally varied by the lifting only, and the sole variation corresponding to the draft in stave work is the tie-up. There are three ties—
1. Straight.—In this each hook has one end only attached to it, and the tie is as under. The rectangle represents the needle board; the dots, the needles; and the numbers, the end to which the hook on the needle is attached.
FIG. 67.
Nos. 1 to 8 will be in the first row of the cumber board to the left-hand side of the cloth.
