Ringer, английский
- Lower deck slang denoting an officer’s rank (e.g., a captain is a four-ringer). see also “striper.”
- The mechanical part that makes the phone ring to indicate an incoming call.
- 1. on a section beam, ringer is a term used for one or more filaments that have left the parent end; as the beam revolves, the filaments continue to unwind, wrapping around the beam (hence the word “ringer”). the severity of a ringer is dependent upon the number of filaments contained therein at the time the filaments break. 2. in slashing, the term ringer is often used when an end breaks on the slasher can, adheres to the can, and continues to wrap around it. this condition should not be confused with ringers on the section beam. ring-spinning: a system of spinning using a ring-and-traveler takeup wherein the drafting of the roving and twisting and winding of the yarn onto the bobbin proceed simultaneously and continuously. ring frames are suitable for spinning all counts up to 150’s, and they usually give a stronger yarn and are more productive than mule spinning frames. the latest innovation in ring spinning involves the use of a revolving ring (also see revolving spinning ring) to increase productivity. ring spinning equipment is also widely used to take-up manufactured filament yarns and insert producer-twist at extrusion.
