back it passes over leading-off rollers, FF, and the scrimp or opening
rail, G, and thence downward to the winding-on center, which cannot be
seen. The winding-on center is driven by friction. As the batch fills
it and tends to wind faster than the machine delivers the cloth, the
driving slips. In addition to a capability of being set at an angle to
the shaft, the stretching pulleys, AA, may be slided upon, so as to
separate or bring them closer together, to allow for the treatment of
different widths of cloths. This adjustment is provided for by mounting
the stretching pulleys, AA, and the band pulleys, CC, etc., on frames,
BB, the ends of which rest, as shown, upon rails, at the back and front
of the machine. The adjustment either for width of piece or for the
angularity (extent of stretching) is easily made by the hand-wheel, L.
By the bevel wheels shown, two cross screws having nuts connected to the
ends of frames, BB, are actuated in such a way that as desired the space
between the back and front of the pulleys may be closed in or opened
out, or the two wheels, maintaining the same angularity, may be
separated or closed in, either adjustment being expeditiously made. The
wheels, HHH, are called center stretching wheels, the use of which is
sometimes advantageous. They act in conjunction with a set of stretching
pulleys, of which one, K, may be seen in illustration. By a proper
adjustment at the latter the piece is bent into a wavy form, where it
passes between the whole of them, the effect of the corrugation being
to loosen the center threads and to allow the piece to be more equally
stretched with those near the selvages and more easily. This part of the
machine may be used or not as required. The production, we observe, was
about 120 yards per minute. The machine is solidly built and well fitted
together, as was obvious to us from an inspection of some in course
of construction at the maker's works. It is also claimed to be of
considerable advantage to bleachers and finishers of white goods,
on account of the uniformity of the stretching causing but small
