In this manner design, [Fig. XXXVII.], is constructed. A, B, C, C´, D, correspond with the same letters used in [Fig. XXXVI.]; hence, it will readily explain itself, as well as the method to be observed in designing for this kind of tie-up. The design runs straight through from A to C, and repeats itself backwards from C to B, finishing at B the first full division.
B-C´ equal A-C,}
C´-D equal C-B,} forming the second division.
Any changes as to different sizes of machines, rows deep of comber-board, or number of divisions, must be executed upon the principle explained in this article.
V. “Straight-Through” and “Point” Tie-ups Combined.
A.—For fabrics requiring for their centres a straight-through tie-up and for their borders a point tie-up, one-half division of it for each border.
Fig. XXXVIII.
These tie-ups are used to a great extent for napkins, handkerchiefs, scarfs, and similar damask fabrics, in which the centre part of the fabric is worked on the straight-through method; the borders on each side on the point tie-up, repeating equally from centre towards the selvedge. In the other two borders to be woven at the beginning and the end of the fabric, the same principle is observed, thus producing four corner squares, only two of which need be designed, as the other two repeat through the arrangement of the tie-up, which must repeat equally towards both sides of the border at the connecting places.
