I find the section in the book Gendai-Kyudo-Kouza that was similar to the page –With/without glove-.
1. Clip the arrow by the thumb and index finger
2. Clip the arrow, and hook the string by the ring finger
3. Hook the string by three or four fingers
4. Hook the string by the thumb and hook the thumb by index finger and middle finger
Each style has each culture.
