A pump has a bearing stand (3) in which a pump shaft (1) is mounted to be driven by an electric motor. The shaft (1) mounts an impeller (9) having blades (10) which cause fluid entering through an axial inlet nozzle (11) to flow, by rotation of the impeller in one direction, through a centrifugal exit nozzle (12) formed by a suitably located quarter toroid (13a), and a half toroid (14), formed as sheet metal pressings. When the impeller (9) is rotated in the opposite direction, the centrifugal nozzle (12) acts as an entry nozzle and the axial nozzle (11) acts as a discharge nozzle. The pump is particularly suitable for treating textile yarns since said one direction of rotation can be used for out-to-in treatment dye liquor flow where relatively high resistance is encountered and said opposite direction of rotation can be used for in-to-out treatment dye liquor flow where resistance is relatively lower.

Apparatus particularly adapted for applying foamed treating liquor to a flat width of a traveling non-woven textile substrate includes a longitudinal tubular foam distribution nozzle one side of which has a plurality of closely-spaced staggered apertures for engaging and applying pressurized foam widthwise across the substrate and a driven drum opposed to the nozzle engaging widthwise the opposite side of the substrate for imparting traveling movement to the substrate. The drum and nozzle cooperate to compress the substrate therebetween in covering relation over the apertures to prevent lateral escape of the foam therefrom and to confine the emission of foam therethrough, thereby to uniformly control foam application across the substrate width as it travels by the nozzle. Limited contact of the apparatus with the substrate prevents frictional pulling and structural damage thereto. The drum is perforated for escape of the air component of the foam and to enhance foam penetration of the substrate. If desired, one apparatus may be employed to achieve full substrate penetration or two serial apparatus may be arranged to treat respectively opposite substrate sides for full penetration.

Cylindrical textile filters of the radially outward filtration flow type such as utilized in textile wet processing systems are cleaned of filtered accumulation in an inclined filter housing wherein the filter is continuously rotated while a spray nozzle travels axially along the length of the filter applying a high velocity spray of cleaning water radially inwardly with respect to the filter. Simultaneously, a shower-like water spray is applied axially through the filter interior to flush the filtered accumulation as it is dislodged by the high-pressure spray nozzle.

Apparatus and method for cleaning filtered accumulation from an annular

A self-cleaning filtering apparatus for use in a material treating system of the type in which treating fluid is recirculated through a treating vessel. The apparatus includes a filtering chamber through which treating fluid flows from a pump to a heat exchanger. A cylindrical perforated filter element in the chamber filters particulate contaminant, such as lint in a textile processing system, onto the element, and a reciprocating cleaning member cleans the contaminant from the surface of the filter element by drawing fluid through an annular slot in a head of the cleaning member, with the fluid being drawn across and through the filter element to remove contaminant therefrom. The contaminant containing fluid is conveyed from the cleaning member back into the treating vessel where it is discharged into a large fabric bag that allows the fluid to filter through into the vessel and obstructs the contaminant for collection in the bag.

Apparatus and method for compressing raw fiber stock into a perforated basket for dyeing in a radial-flow dyeing machine. A hollow container is provided by a perforated cylinder section stacked separably on an imperforate section for loading fiber stock into the common interior. A piston movable under force of water pressure is located in the imperforate section to compress the loaded fiber stack into the perforated section. A closure plate is movable with the piston and is attachable to the perforated section following fiber compression to close the perforate section with compressed fiber therewithin, such that the perforated housing may be removed and used as a dyeing basket. A central core element is secured to the closure plate and is movable therewith to maintain an open center in the dyeing basket for use of the basket in a radial dyeing machine.

Means for applying foamed treating liquor to a flat width traveling textile substrate using a cylindrical supporting member extending axially transversely across the width of the substrate and supporting a projecting applicator nozzle. A circumferentially extending distribution chamber is formed on the cylindrical supporting member by a cover plate mounted in spaced relation on the cylindrical supporting member by resilient side strips to which the cover plate is tightened circumferentially in sealing disposition. The distribution chamber diverges from an inlet port adjacent the nozzle circumferentially around a major extent of the cylindrical supporting member to the full width of the nozzle. End closures are slidably manipulated in the ends of the nozzle to limit the transverse extent of the nozzle opening in following relation to variations in the transverse positions of the edges of the traveling substrate in response to a sensing device. A plate-like projection may be provided across the distribution chamber adjacent the nozzle to restrict flow of the foamed treating liquor and thereby assure proper uniform distribution of the liquor across the distribution chamber to the nozzle. The projection preferably tapers from a maximum circumferential extent at the center to minimum extents at the outer ends for further assurance of proper transverse distribution of the foamed treating liquor across the distribution chamber to the nozzle.

Means for applying foamed treating liquor

Treating liquor is applied to open-width textile substrate by pressure feeding the liquor in foamed condition to a distribution chamber having gently changing cross sectional areas and contours and arranged to deliver the foamed treating liquor evenly widthwise of the substrate through an application head past which the substrate is caused to travel under conditions that result in liquefying the foamed treating liquor in the course of application to the substrate.

Means for applying treating liquor to textile substrate

A method, and means for use in performing the same, are disclosed by which a core tube on which a yarn package has been wound may be readily removed while concurrently replacing the removed winding tube with a core suitable for dyeing. An expandable and reciprocable chuck is operated cyclically for this purpose in relation to a plate member on which the yarn package is manually placed for the core removal and dye core replacement. In certain circumstances the method and means disclosed are also adapted for removing the dye core after dying and replacing it with a tube of the sort initially used for winding.
