These eight ends, forming the first complete row of the comber-board, will use the first row of both machines; the second row of the comber-board will use the second row of both machines; and so on, until every row of the comber-board, with corresponding row of the Jacquard machine, is taken up. In the drawing we have indicated, as usual, besides the first row, the last row of the machine and the comber-board; or, in other words, we show the threading of

This method of using two Jacquard machines, on the principle explained, is employed on Jacquard looms for dressgoods figured with an extra warp, on upholstery goods, and similar textile fabrics.
[Fig. LVII.] shows a fabric design for a curtain, to be executed on the straight-through tie-up in two sections.
C.—Using one machine and one comber-board: the machine unequally divided and the comber-board equally divided.
To explain, take the regular upholstery fabric tie-up known as “petty point,” on a 600 machine 12 rows in depth. 600 ÷ 12 = 50 + 2 rows reserve = 52 rows in width. We find used—
