Abstract
The invention relates to an apparatus for the treatment of continuously transported lengths of textile material comprising a housing within which is a rotatable drum filter, an extraction and cleaning nozzle extending approximately axially over the outer peripheral surface of said drum filter, and a blower and duct for establishing a circulating air stream through the textile material and the filter. Fibres extracted from the filter by the nozzle are conducted to and deposited on an air filter that also is located in the housing in a position to be readily accessible for maintenance.
Claims13
Apparatus for the air treatment of textile material comprising a housing;
- means for moving a length of material continuously through said housing;
- an air blower in said housing for moving air through the textile material and thereby entraining fibers from said textile material;
- a rotary drum in said housing downstream of the textile material;
- duct means communicating between said blower and said drum for establishing in said housing a circulating air stream therebetween;
- a fibre filter carried by said drum for rotation therewith;
- means rotatably mounting said drum in such position that said air stream passes through said fibre filter, thereby enabling fibres to collect on a surface of said fibre filter;
- a cleaning nozzle in close proximity to said surface of said fibre filter and extending axially over the length thereof;
- an air filter in said housing;
- a conduit coupling said nozzle to said air filter;
- ejector means accommodated in said conduit between said nozzle and said air filter for establishing a flow of air from said nozzle toward said air filter;
- and means coupling said ejector means to a source of pressure fluid, whereby said nozzle is operable to remove fibres from said fibre filter surface and deposit them on said air filter.
