COTTON SPINNING.

The device for winding the lap is exactly the same in detail as that used on the sliver lap machine.

The laps, put in at the back of the ribbon lapper, are usually made about one inch less in width than those required for the comb, as they spread some when passing through the draft rolls.

The ribbon lapper is provided with two stop-motions, one which stops the machine immediately if a lap runs out at the back and one, called a full lap stop-motion, which regulates the length of the laps, so that they will all be wound to the same diameter.

Fig. Ill shows a diagram of the gearing of the ribbon lapper. The driving pulleys are 16 inches in diameter by 3 inches
