ROVING ROOM

1. A drawing frame showing the sliver of cotton passing through the machine.
2. A slubber showing the sliver passing through and wound on bobbins.
3. Roving machine showing the cotton passing from one bobbin through the roller to another.

The objects of the spinning process are:

1. Completion of the drawing out of the cotton roving to the required size.

2. Insertion of the proper amount of twist to give the thread produced strength.

Excessive speed causes defects in the yarn and undue wear and tear on the machine.

There are two methods of spinning: ring spinning and mule spinning. The mule spinning is the older form. There are but few mule frames in operation in this country.

Mule Spinning. The function of mule spinning is to spin on the bare spindle, or upon the short paper tubes, when such are required to form a base for the cop bottom. The mule will spin any counts of yarn required, and is especially adapted for yarn in which elasticity and “cover” are essentials. Hosiery yarns are produced on the ordinary cotton mule and are very soft spun.
