Explain the principle of any cross border dobby, including the method of changing over from one pattern to the other. 4. A positive, indirect taking-up motion for a rayon loom, la arranged, as follows: The ratchet wheel, which la the change wheel, is compounded with a single worm (equivalent to a wheel of 1 tooth) , which drives a worm wheel of 60 teeth on the take-up roller. If the number of teeth in the ratchet wheel is to be equal to the number of picks per half inch in the cloth, calculate the necessary circumference of the take-up roller allowing 1 1/2 per cent for contraction. Explain how damage to cloth by friction is minimised in a motion of this kind. 5. Automatic let-off motions are classified as "negative ''controlled negative", and "controlled positive".
