[Fig. LV.], a fabric design for cloaking for straight-through tie-up in two sections. A, face warp, black silk; B, back warp, black cotton.
B. Using two machines and a comber-board having equal sections.
Fig. LVI.
Sometimes two or more machines are employed in producing fabrics having two systems of warps; each machine working on its own system. In this manner [Fig. LVI.] is executed, representing a straight-through tie-up arranged for two Jacquard machines, S and H, in which the warp is drawn in the Jacquard harness as follows: one end from machine S, one end from machine H. For explanation two 100 Jacquard machines are used for the purpose of simplifying the arrangements of laying out and threading the comber-board. A larger Jacquard machine for the illustrations would require more leashes, and the explanation would be more difficult.
The comber-board, a, b, c, d, is divided into two equal parts, S and H. Each part containing the harness-cord for one machine only. The drawing of the tie-up is arranged for two divisions, and also readily explains any tie-up for more divisions.
The leasing of the Jacquard harness, K, is arranged (as illustrated in the drawing by leash-rods p and r) to commence as follows:
1st end: harness-cord fastened to No. 1 needle of machine, S; 2d end to No. 1º needle of machine, H; 3d end to No. 2 needle of machine, S; 4th end to No. 2º needle of machine, H; 5th end to No. 3 needle of machine, S; 6th end to No. 3º needle of machine, H; 7th end to No. 4 needle of machine, S; 8th end to No. 4º needle of machine, H.
