The position of this twine in working is shown in [Fig. 38]. C, the crossing of the two twines preparatory to forming the loop, is illustrated. The mechanical construction is such that needle, a, is withdrawn from loop at the same time needle, b, commences to rise, placing the twines in position shown in [Fig. 41]. Needle, b, will in turn pull down as soon as needle, a, is ready for moving forward. By moving needle, b, down, its twine will form a loop, [see [Fig. 42]], held in its position by the “loop-guide,” [Fig. 37]. Through this loop, needle, a, is again inserted. Needle, b, will leave the card below as soon as needle, a, is in its loop. At this juncture the cards will be moved by means of the catch and chain of links one hole or one space between cards, whichever may be required. After this is done, needle, b, will rise in its new place, and at the same time needle, a, commences its backward journey through the loop shown and explained in Figs. [38] and [41] at the beginning; thus ready for a repetition of the two movements.

The foregoing explanations will give the principle of this card-lacing machine as follows: “One needle holds the other’s twine until the other needle has moved one point ahead.”
