   Alternatively, a sheave can be integrated and installed within the housing frame. In this case, the system can be set up anywhere around the drum. Oceanographic installations that spool rope up to 46 layers have demonstrated that level winders give synchronized and controlled spooling in the harshest, most testing conditions.

3. Anti-twister mechanism - Wikipedia

   en.wikipedia.org/wiki/Anti-twister_mechanism

   The slip rings are attached to one part of the machine, and a set of fine metal brushes are attached to the other part. The brushes are kept in sliding contact with the slip rings, providing an electrical path between the two parts while allowing the parts to rotate about each other. However, this presents problems with smaller devices.

4. Reel - Wikipedia

   en.wikipedia.org/wiki/Reel

   A reel is a tool used to store elongated and flexible objects (e.g. yarns/cords, ribbons, cables, hoses, etc.) by wrapping the material around a cylindrical core known as a spool. Many reels also have flanges (known as the rims ) around the ends of the spool to help retain the wrapped material and prevent unwanted slippage off the ends.

   Some reels or skein winders are made without the gear mechanism (see swift (textiles)). They perform the same function, but without the "clock" or pop to aid the spinner in keeping track of the length of thread or yarn produced. A niddy noddy is an even simpler version.

   The twist drill bit is the type produced in largest quantity today. It comprises a cutting point at the tip of a cylindrical shaft with helical flutes; the flutes act as an Archimedean screw and lift swarf out of the hole.

   Drawworks (#7) is the mechanical section that contains the spool, whose main function is to reel in/out the drill line to raise/lower the traveling block. Drill bit (#26) is a device attached to the end of the drill string that breaks apart the rock being drilled. It contains jets through which the drilling fluid exits.

9. Tripping (pipe) - Wikipedia

   en.wikipedia.org/wiki/Tripping_(pipe)

   Vertical Drill Bit. Drill bits wear and tear like most any other piece of equipment. Once a bit becomes too worn to drill at an adequate rate or make a full-gauge hole, or if the bearings are thought to be near failure, a trip is undertaken to replace the bit. A trip is not considered a bit trip when the purpose of replacing the bit is to ...
