raises at low speed to the top of 41 passes through filter into blower 42 and back to the cover 22 water valve 40 and blower 42 are shut off automatically when the loom stops in fig9 the solids removal sub system is represented schematically contaminated air is returned from the shed vacuuming device 22 the yarn break detector area 21 and the filling yarn area 45 through tubes 54 31 a and 32 individual flow rates will be controlled by valves 37 the adequate amount of air will be bled by valve 36 in order to adjust the correct under pressure between cover 23 and vacuuming device 22 in high speed looms the main friction points and bearings are lubricated either by a central oil pump or more frequently by independent oil sinks and dispersing devices as already stated power consumed by the loom is totally converted into heat and most of it transmitted to the oil observations and measurements made on gripper looms showed that between 40 65 of the total heat is absorbed by the oil and then dissipated into the room air fig1 shows three independent oil sinks 55 and their usual oil level their number may vary between 2 and 8 depending on model and manufacturer overflowing oil is conducted through an adequate piping system 56 to an auxiliary sink 57 the pump 58 impulses the oil from said sink through the heat exchanger 59 and the piping system 63 back to the sinks 55 the heat exchanger will be of the plate type temperature is controlled by devices 62 for oil and 60 for water adjusting the water flow rate in such a way as to maintain.
