Asphalt emulsion finds a more general use as a tackifier to hold rovings and straw in place. |

At the other end of the process of manufacture, there were merchants who organized the ginning and bowing of the raw cotton and sold the rovings to the spinners. |
|
The women would then spin these rough rovings into yarn wound on a spindle. |
|
Carding completed the disentangling process, creating rolls of wool called rovings. |
|
The throstle and the later water frame pulled the rovings through a set of attenuating rollers. |
|
On the outward motion, the rovings are paid out through attenuating rollers and twisted. |
|
Connection is then established between the attenuated rovings and the spindles. |
|
Creeling involved replacing the rovings bobbins in a section of the mule without stopping the mule. |
|
Its success was limited in that it required the rovings to be prepared on a wheel, and this was limited by the need to card by hand. |
|
The rovings when extended passed through two horizontal bars of wood that could be clasped together. |
|
The rovings are collected in a drum and proceed to the slubbing frame which adds twist, and winds onto bobbins. |

|
Since combining several slivers produces a very thick rope of cotton fibres, directly after being combined the slivers are separated into rovings. |
|
A wheel was rapidly turned as the frame was pushed back, and the spindles rotated, twisting the rovings into yarn and collecting it on the spindles. |
|
A set of eight rovings was attached to a beam on that frame. |
