This fabric can also be executed on the tie-up explained through [Fig. XLI.], as follows:
Border = a to i on point tie-up, e for centre or point.
Centre = 1st division i to k, straight-through.
Straight-Through and Point Tie-ups Combined.
E.—Mixed Tie-up.
Containing in one repeat of the design the straight-through tie-up and the point tie-up, one full division, for the centre; the point tie-up, in half divisions, repeating once through on each side of the fabric, to make the border. These arrangements of tie-ups are used to a great extent in the manufacture of damask fabrics of every denomination.
The principle of using mixed tie-ups, [Fig. LII.], is found in the necessity of producing large designs, containing varied effects, with a proportionally smaller Jacquard machine. Under whatever management the straight-through and the point tie-ups are combined, their principle remains undisturbed. Every time we arrange a Jacquard loom on a mixed tie-up, we must consider that any subsequent design must be arranged with reference to the same principle as the one in use, otherwise the work must all be rearranged, which would have to be done even for the smallest change in the number of ends for each effect.
