There is a tool called a rotary index. What does it doand used for?
Answers:
A rotary index table is a device used to convey parts for assembly, machining, packaging, finishing, or other manufacturing operations. This index device conveys the parts in a rotary or dial motion, stopping intermittently in station "to dwell" for a fixed period of time. The dwell time and index time between stations are programmed and variable.
The number of index stations of a rotary index table is predetermined and specified at the time of purchase. Stations range from a minimum of two up to thirty-six in a 360° work circle. Stations on a rotary index table are typically set at 20°, 40°, 60°, 120°, 180°, etc. Rotary index tables provide controlled acceleration and deceleration from station to station in a clockwise or counterclockwise mode. Index times can be as low as .20 seconds, and over 150 cycles per minute.
Rotary index table diameters range from 5" to 40". Electric motors are the most common drive source, however, rotary index tables can be driven by air and fluid motors. Most rotary index tables are dedicated and installed in automatic machines. Rotary index tables are specified based on inertia load capacity, work circle radius, and speed of index time.

It's a file full of index cards in order (usually alphabetically), usually filled with names, phone numbers and addresses. The "rotary," comes from "rotary phone."

Its a proctology tool
if you are referring to a rotary index that holds information, phone numbers, addresses, etc.
Then you basically have a bunch of index size cards that you can attach business cards, or manually write down the info on.
The "rotary" does not come from the old days of the rotary phone, it comes from the fact that the index is mounted on a spool, which allows the user to rotate it to the correct index location.
