A fluid filter is provided for separating entrained particulate matter from a moving fluid stream. The fluid filter includes a filter structure for mounting the filter on a supporting surface, a plurality of nested filter frames, and a filtration medium carried by each of the filter frames. The filter structure has a fluid inlet and a fluid outlet for conveying the fluid stream therethrough. The nested filter frames are located within the filter structure in spaced-apart relation to each other. The filtration media are interposed between the fluid inlet and the fluid outer of the filter structure, and define on one side thereof an upstream filter surface and on the other side thereof a downstream filter surface.

Fluid filter for separating entrained particulate matter from a moving

The invention is a fluid filter and method of separating entrained particulate matter from a moving fluid stream. The fluid filter includes a filter structure for mounting the filter on a supporting surface, a plurality of nested filter frames, and a filtration medium carried by each of the filter frames. The filter structure has a fluid inlet zone and a fluid outlet zone for conveying the fluid stream therethrough. The nested filter frames are located within the filter structure in spaced-apart relation to each other. The filtration media are interposed between the fluid inlet zone and the fluid outlet zone of the filter structure, and define on one side thereof an upstream filter surface and on the other side thereof a downstream filter surface.

Apparatus for use with a traveling cleaner for textile machines, particularly ring spinners, operable to strip yarn ends from the whirls of the spindles for the bobbins of the ring spinner apparatus. A whirl cleaner blade is pivoted to the frame of the ring spinner adjacent each spindle so that its free blade end may be displaced into engagement with the whirl of the spindle by a jet of compressed air impinged against the blade. The compressed air is supplied by a nozzle suspended from the carriage of the pneumatic cleaner to impinge against the blade. The compressed air is fed from a central junction box under the track for the carriage through the energy chain which houses the power supply cables for the carriage. From the carriage, the compressed air is piped to the nozzle positioned at the level of the spindle whirls. Control means is provided to activate the flow of compressed air for a selected time period which achieves stripping of the whirls of all of the spindles in the apparatus during the time when the ring rail is disposed a distance above the spindle whirls. In installations where the pneumatic cleaner additionally services sections of textile machinery which do not have spindles needing stripping, the flow of compressed air is also controlled by the travel of the cleaner between sections.
