used to counter-balance that shrinkage.
5. DRAWING-IN THE WARP IN HARNESS AND REED Here we must specify the number of dents that contain the same number of ends, and whether the latter are single or double, also the number of shafts and the method of drawing-in. [Page 71] 6. WARPING TICKET To make out the warping ticket, we need to ascertain the total number of ends, whether leased single or double, and the arrangement of the colors. 7. HARNESS ARRANGEMENT This is governed by the number of ends to be drawn in and the necessary shafts. If we have, for instance, 100 threads per inch to be drawn on 4 shafts, we must give each shaft 25 heddles per inch. There are generally between 25 and 45 heddles per inch on one shaft. 8. REDUCTION OF THE FILLING Here we state the number of picks per inch, give directions as to doubling, if such is necessary, and if more than one color or shuttle is used, the rotation thereof. 9. CALCULATION OF WARP AND FILLING The system adopted in this country for specifying the size of silk is based |
