Abstract
A lubricating method and apparatus for a circular knitting machine which involves inputting operating conditions for the circular knitting machine from an operating conditions input device 30, after which a pump squirt quantity per squirt is computed by a squirt quantity computing device 33 and set in a squirt quantity setting device 21, a pump squirt velocity is computed by a squirt velocity computing device 34 and set in a squirt velocity setting device 22, and an intermittent pump operating period is computed by an intermittent period computing device 35 and set in an intermittent period setting device 24. Subsequently, a start signal is sent from a start signal sending device 25 after each set intermittent period, and a pump drive device 23 drives the pump 12. As a result, an appropriate quantity of lubricating oil is squirted from a nozzle 13 towards a cam groove 4 of a cam 5 for a duration of at least one revolution of a row of needles 1 of the circular knitting machine. Wastage of lubricating oil can thus be reduced to an insignificant amount, and the lubricating oil can be spread uniformly to all required locations without lubricating oil contamination of the surroundings, thereby preventing nonuniform lubrication and ensuring machine durability.
