Abstract: 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.

Abstract: A method and apparatus for winding yarn to produce a wound yarn package having a variable density profile. The variable density profile in the wound yarn is produced by variably tensioning the yarn during the winding process by an electrical apparatus which is responsive to a programmed control signal to provide variable tension on the yarn. The density profile thus produced is preferably a progressively variable density profile. In a preferred embodiment, the method is carried out with a precision winding machine with an electromagnetic tensioner. A controlled sequence of control signals is applied to the tensioner to provide a correspondingly varying tension on the yarn. The application of controlled tensioning to dyeing beams by progressively increasing tensioning warping yarn along the length of the beam has also shown improved results in resisting dye liquor channeling and blowout and permitted a beam geometry with a greater capacity.

Abstract: This invention is directed towards improvements in collapsible dye tubes, commonly referred to as dye springs. The dye springs of the present invention are characterized in that they are resiliently compressible and are further able to withstand elongation. The dye spring has a surface area of cylindrical shape with elements disposed between rings at the end of the tube. The elements insure that the dye spring surface area remains open when the dye spring is in a compressed state so that dye will be able to flow radially outwardly through the tube and thereby dye the yarn wound around the tube. The elements further insure that the degree of elongation experienced by the spring during winding operations is substantially diminished or even eliminated.

Abstract: A spring dye tube for use in dyeing textile yarns has a generally open-ended, cylindrical configuration with a latticed side wall. It is resiliently compressible in a longitudinal direction, and includes longitudinal stabilizing elements to prevent growth or collapse during high-speed winding operations. In turn, these longitudinal stabilizing elements buckle and collapse when the spring dye tube as a whole is compressed in a longitudinal direction. The longitudinal stabilizing elements may be disposed in pairs separated by a gap, or singly. In the latter case, a longitudinal groove may be provided along the length of the element; the element will split along this groove when the tube is compressed. In either case, this provides a means for dye to pass through that portion of the tube during use in a dyeing operation. The longitudinal stabilizing elements can resemble thin membranes in appearance, the membranes being of greater width than thickness.

Abstract: A yarn roll carrier tube and method of employing same to effect uniform compression of a yarn roll mounted on said tube is disclosed. The tube includes a central compressible portion, a contoured portion at one end, and an annular opening having a recessed stop portion at the other end. The tubes are sized such that the contoured portion may be inserted into and frictionally retained within the annular opening of a similar tube by a predetermined mount dictated by the position of said stop shoulder by the exertion of a compressive force exerted by one said tube against the other. Yarn rolls mounted on adjacent said tubes are partially compressed by the insertion of one tube into the other into said nested position, said insertion resulting in a preferential compression of the central portions of the yarn rolls. Subsequent compressive forces of a greater magnitude when exerted against the tubes result in axial foreshortening of the tubes and greater compression of the yarn rolls.

The ribs have projections (16) which fit into recesses (17) of the sleeve sections for arresting the ribs in the sleeve sections in a plurality of different positions, whereby the length of the lap creel is changeable.

Abstract: Cap members are placed at the lower end of the perforated bottom spool sleeve and at the top end of the perforated top spool sleeve of a series of package-containing spools mounted at a perforated tube or sword. The cap members prevent, during treatment of the package-containing spools with a suitable treatment fluid or agent like, for example, a dyeing or bleaching fluid, the escape of such treatment fluid at each of the connecting locations between the perforated sleeve of the bottom spool and a base plate as well as between the perforated sleeve of the top spool and a chuck-type or clamping closure member. The end portions of the perforated sleeves are constructed such that no treatment fluid can escape at the connecting locations between the perforated sleeves of adjacent spools in the series of package-containing spools mounted at the associated perforated tube.
