FIG. 6. machine shown in Figure 7 is needed for winding and measur-ing fine and light fabrics. The tension arrangement is similarto that of the other machine, and the measuring is done sub-stantially in the sameway. A hand lever, re- .inforced by a weight,holds the jaws in placeand automatically ad-justs them to any slightvariations in the lengthof the boards. Jaws areobtainable fitted (orcardboards, paper tubesand all other devices inactual use. Machines ofthis type are built up toa width of 72 inches. The machines are soconstructed that a plat-form containing thecloth to be measuredand wound can be rolled underneath without preventing theoperation of the treadle by which work is started and unrolling frame, with a large apron is used in some caseswhere the fabric to be measured comes in large rolls. In thatway the tension arrangement, of the machine has entire con-trol of the feeding.
