2. Sectional Warping.

This system comprises the following operations, namely—

1. Reeling yarn into hanks.

2. Hank-dyeing and sizing.

3. Winding on to warpers’ bobbins by a drum-winding machine.

4. Sectional warping, by which a warp is wound in sections upon wooden or compressed paper blocks, with warp-ends in the same relative position that they are required to occupy in cloth. Each section forms a complete unit of the full warp, and when the required number of units are prepared, they are placed together side by side, and compressed upon a mandril; then the yarn is unwound from all sections simultaneously, and wound on to a weaver’s beam.

5. Twisting-in or drawing-in.

Preparation of Weft Yarn.

If weft yarn is to be woven in a grey state, it is rarely that it requires to undergo any operation after it leaves the spinner. Grey cops and ring bobbins of weft are usually placed in a shuttle and woven direct; but if they are too large for a shuttle, their yarn is transferred on to wooden or paper bobbins by means of pirn winding.
