On each side of every repp stripe two ends of the satin warp must be entered on the 2 binder shafts (2d section), to prevent the ends of the satin to slide over into the repp stripes.

This warp has to be beamed in stripes.  Make out a diagram for the warper the same as shown in Fig. 95.

[Illustration:  Fig. 95]

#Harness#—­Fig. 95 shows how to make a diagram of a harness for a Pekin.  The heddles are marked per one shaft.  As the repp stripes are only small ones, we use for the satin a full harness, that is, one without open spaces for the repp stripe.  All together we have in the satin warp 6888 single and double ends to draw in; of these 252 ends are used for binders, on both sides of the repp stripes.  Thus remain for

8 shafts, 6636 heddles per 201/2 inches

#Reduction of Filling#—­Per 1 inch, 144 picks, 1 end.

#Warp Calculation#—? lbs. = 6132 ends (1680 ends sky).
1 end = 106 yards.
1000 yards = 1,35 drams (sky 1,15 drams).
256 drams = 1 lb.
100 = 104 (4% waste).

6132x106x1,35x104
------------------- = 3,56 lbs. for black, or 3 lbs. 8,96 ozs.
1000x256x100
1680x106x1,15x104
------------------- = 0,83 lbs. for sky, or 0 lbs. 13,28 ozs.
1000x256x100

[Page 99]

? lbs. = 504 ends.
1 end = 110 yards.
840 yards = 1 skein. 
(No. 100/2) 50 skeins = 1 lb.
100 = 104 (4% waste).

504x110x104
------------- = 1,37 lbs. scarlet cotton, or 1 lb. 5,92 ozs.
840x50x100

#Filling Calculation#—? lbs. = 100 yards.
1 yard = 36 inches.
1 inch = 144 picks.
1 pick = 21 inches.
36 inches = 1 yard.
1000 yards = 2,8 drams.
256 drams = 1 lb.
100 = 108 (8% waste).

100x36x144x21x2,8x108
----------------------- = 3,57 lbs., or 3 lbs. 9,12 ozs.
