All the patterns hitherto mentioned have been single doups. A more highly-ornamental class of goods is made in double-douped cloth. Here two-doup healds are used, and, consequently, half of the crossing threads may be weaving plain at the same picks that the others are douping, and then a reversal is made--the first half commencing to doup while the other section is weaving plain. Thus, check patterns are made alternately gauze and plain. Double-douped netting and stripe patterns may also be made. With a single doup, only stripe patterns may be produced with the gauze running either transversely or longitudinally. For more complicated patterns three or even four doups are employed. [Illustration: FIG. 59.] Gauze patterns are not generally marked on paper as are other fabrics, but sketched thus:-- [Illustration: FIG. 60.--GAUZE SKETCH.] HANDKERCHIEFS. Handkerchiefs are made in cotton, either by the drop-box, the dobby, or by a handkerchief motion. We are referring now to those made without colour, with ribbed side and cross borders. A stripe border is made by warping the necessary coarse ends (to form the selvage) with the plain ends. To put in the cross border, either the drop-box loom is used with two or more shuttles having different counts of yarn, or, as is more general, the shed is kept open for the reception of several picks of weft in the same counts as the body of the handkerchief. This is easily done by the dobby, which also continues to hold the weft at each selvage by a few plain ends worked from a different jack, or by a catch cord. It is impossible to have a lattice with as many lags as there are picks from heading to heading, consequently lags are pegged to weave the heading only, the lattice being stopped during the time that the plain body of the handkerchief is being woven. In the double-lift dobby it is possible to stop it, so that the pegging of the lags where the motion of the lattice is arrested will suffice to weave plain until motion is again communicated to the lattice. Sometimes a special handkerchief motion is used. In this arrangement a chain of lags is arranged, each lag having holes for three pegs. By means of this motion, which is shown in Fig. 61, “a border can be obtained without drop-boxes or dobby, _and without reducing the speed of the loom_. The tappets, which are of the usual form for plain weaving, are not secured to the tappet shaft, but are driven from it through the medium of a clutch, which, when disengaged, allows the shaft to continue revolving whilst the tappets remain stationary; thereby enabling any required number of picks, even or odd, to be put into the same shed, according to the length of time they are kept in this condition. The clutch is under the control of a set of lattice, which cause the disengagement of the clutch, and a succession of pegs causes the tappets to remain out of action according to the desired number of picks required.”
