  • Patent number: 5205377
    Abstract: The lubricant mist is supplied in timed fashion to at least one nozzle (31, 36, 40, 45) associated with a lubrication station in the zone of movement of a moving part (32, 37, 41 and 34 respectively). The timed supply of the mist is effected in dependence upon the position of a drive shaft from which the moving part derives its movement. The lubricant mist can therefore be supplied to the lubrication station in an accurately dosed quantity only when it is needed there. A possible use of the lubricating method is for looms where it is particularly important that the web of cloth produced on the loom should not be soiled by lubricant.
