The bobbins, as they pass likependulums between the warp threads, are made to oscillate, and throughthis oscillation the threads twist themselves or become twisted with thewarp threads, as required by the pattern that is being produced. Asthe twisting takes place, combs compress the twistings, making themmore compact. If the bobbin threads be made tight and the warpthreads slack, the latter will be twisted upon the former; but if thewarps are brought to a tension and the bobbin threads be slack, thenthe latter will be twisted on the warps.

The combs are so regulatedthat they come clear away from the threads as soon as they have pressedthem together, and fall into position ready to perform their pressingoperations again. The contrivances for giving each thread a particulartension and movement at a certain time are connected with an adapta-tion of the Jacquard system of pierced cards. The lace machine ishighly complicated, much of its complexity being due to the mechanism. L8 Lace: Its Origin and History. In which the oscillating or lateral movements arc produced. Expertworkmen prepare the working drawings for the lace machine, and alsoperform the more important duties in its operation, but a large part ofthe work is carried on by women and girls. One of the most interesting developments of the lace industry hasbeen the gradual evolution from the work of the hand toilers to theutilization ^\ complex machinery. In addition to the Leavers machine,which is referred to elsewhere in extenso, the embroidery machine playsa very important part in the making of laces. From 1870 to 1880, variousefforts had been made to produce lace on the embroidery machine, andit was during this decade that the first success was achieved in themaking of Oriental or net laces in Plauen. This was the first actualproduction of lace from the embroidering machine, and this sort of lace,which still exists to-day, is really an embroidery on a net, althoug
