Coming down to the question of machine-made lace, it is necessary to observe at the outset that the same distinctions that exist between the genuine and the imitation do not obtain as applied to these fabrics. In other words, the knowledge that lace is a product of the frame rather than the fingers in no sense condemns it. For to such a high plane has the mechanical production of lace been lifted that one is almost tempted to say that the products vie in beauty of design and perfection of finish with the lace produced by hand. That there is warrant for this seeming exaggeration is borne out by the fact that not infrequently it is impossible for experts to tell the difference between two specimens of lace of the same design, one made by hand and the other by machine.
What inventors have accomplished in this respect is truly marvelous. In the beginning their efforts were not at all satisfactory, and the history of machine-made lace abounds with pathetic instances of men who sought in vain to duplicate with fidelity, by means of mechanical devices of hundreds of types and patterns, the dextrous touch of the human hand.
W. Felkin, in his history of lace manufacture, says that lace net was first made by machinery in 1768. Other authorities place the date as between 1758 and 1760. In 1809 bobbin net was invented, and in 1837 the Jacquard system was applied to the bobbinet machine.
Mrs. B. Palliser, in "The History of Lace," says of the invention of machinery for the production of lace that the credit is usually assigned to Hammond, a stocking framework knitter of Nottingham, who, examining one day the broad lace on his wife's cap, thought he could apply his machine to the production of a similar article. His attempt so far succeeded that, by means of the stocking frame invented in the previous century, he produced, in 1768, not lace, but a kind of knitting of running loops or stitches.
In 1777 Else and Harvey introduced at Nottingham the pin or point net machine, so named because made on sharp pins or points. Point net was followed by various other stitches of a lacelike character, but despite the progress made, all efforts at producing a solid net were futile. It was still nothing more than knitting, a single thread passing from one end of the frame to the other, and if a thread broke the work was unraveled. This was overcome in a measure by gumming the threads, giving the fabric a solidity and body not possible without resorting to some artificial method of this sort.
The great problem inspired the efforts of numberless inventors, and many attempts were made to combine the mechanism used respectively by the knitter and the weaver, and after many failures a machine was produced which made Mechlin net.
There are few histories bearing upon the invention of labor-saving devices that are so replete with the records of failure as is the history of the attempt to produce a practical lace machine. John Heathcoat, of Leicestershire, England, was the inventor of the machine for making bobbin net. His patents were taken out in 1809, and to him must be accorded the credit of solving for the first time the problem that had vexed the minds of so many inventors and had depleted the purses of so many capitalists.
The bobbin net machine, so named because the threads are wound upon bobbins, first produced a net about an inch in width, afterward, however, producing it a yard wide.
It was the application of the celebrated Jacquard attachment to the lace machine that has made possible the duplication of practically every pattern of lace made by hand. The machine of Heathcoat was vastly improved by John Leavers, also of Nottingham, and the types produced by him are still in use throughout England and France, though, of course, there are in these days a large number of different
types of machines bearing different names, but the principle of the Leavers machine, more or less modified, obtains in practically all of the devices. Therefore a description of the process of lacemaking by the Leavers frame will serve as a description for all.
The number of threads brought into operation in this machine is regulated by the pattern to be produced. The threads are of two sorts, warp and bobbin threads. Upward of 9,000 are sometimes used, sixty pieces of lace being made at once, each piece requiring 148 threads (100 warps and 48 bobbin threads). The supply of warp threads is held upon reels, the bobbins carrying their own supply. The warp threads are stretched perpendicularly and about wide enough apart to admit a silver quarter passing edgeways between them. The bobbins are flattened in shape so as to pass conveniently between the warps. Each bobbin can contain about 120 yards of thread. By most ingenious mechanism varying degrees of tension can be imparted to warp and bobbin threads as required. The bobbins, as they pass like pendulums between the warp threads, are made to oscillate, and through this oscillation the threads twist themselves or become twisted with the warp threads, as required by the pattern that is being produced. As the twisting takes place, combs compress the twistings, making them more compact. If the bobbin threads be made tight and the warp threads slack, the latter will be twisted upon the former; but if the warps are brought to a tension and the bobbin threads be slack, then the latter will be twisted on the warps. The combs are so regulated that they come clear away from the threads as soon as they have pressed them together, and fall into position ready to perform their pressing operations again. The contrivances for giving each thread a particular tension and movement at a certain time are connected with an adaptation of the Jacquard system of pierced cards. The lace machine is highly complicated, much of its complexity being due to the mechanism by which the oscillating or lateral movements are produced. Expert workmen prepare the working drawings for the lace machine, and also perform the more important duties in its operation, but a large part of the work is carried on by women and girls.
One of the most interesting developments of the lace industry has been the gradual evolution from the work of the hand toilers to the utilization of complex machinery. In addition to the Leavers machine, which is referred to elsewhere in extenso, the embroidery machine plays a very important part in the making of laces. From 1870 to 1880, various efforts had been made to produce lace on the embroidery machine, and it was during this decade that the first success was achieved in the making of Oriental or net laces in Plauen. This was the first actual production of lace from the embroidering machine, and this sort of lace, which still exists to-day, is really an embroidery on a net, although usually designated as lace. A few years later a discovery was made which effected a great change in the making of laces on the embroidery machine. This was the principle of embroidering on a material which was afterward removed by a
