Abstract

In the rapier or gripper weaving machine a rapier or gripper rod is moved to-and-fro by a drive gear or wheel. An oil lubricating device is provided whose spray nozzle opens in the vicinity of the drive gear or wheel. This spray nozzle is connected to a pressure conduit located at the exit or outlet side of a mixing chamber. In the mixing chamber, a predeterminable quantity of oil taken from an oil reservoir can be admixed with a continuously transmitted flow of compressed air. A timer serves for the periodic activation of an oil dosing and injecting device located upstream or forwardly of the mixing chamber. The dosing action controlled by the timer periodically mixes a predetermined volume of oil into the continuous flow of compressed air being supplied to the spray nozzle. The spray nozzle is a molecular atomizing nozzle. These measures enable an absolutely accurate, constant and adjustable quantity of oil to be admixed with the flow of compressed air and further provide a practically droplet-free mist of oil at the drive gear or wheel of the rapier or gripper rod.

a pressurized conduit with which there is operatively connected said spray nozzle;
said oil lubrication device comprising a mixing chamber having an outlet;
said pressurized conduit being connected to said outlet of said mixing chamber;
said oil lubrication device further comprising;
means for continuously transmitting a flow of pressurized air through said mixing chamber;
an oil reservoir for supplying predetermined quantities of oil to said mixing chamber for admixture with said continuously transmitted flow of pressurized air through the mixing chamber;
an oil dosing and injecting device arranged upstream of the mixing chamber and operatively connected with said mixing chamber;
a timer provided for the periodical operation of said oil dosing and injecting device to periodically admix a predetermined volume of oil with the continuous flow of pressurized air supplied to the spray nozzle;
and
said spray nozzle being a molecular atomizing nozzle.
