Abstract: A cylindrical or conical bobbin (1) resiliently compressible both in axial and in radial direction and supporting textile strands to be subjected to a heat and/or wet treatment has an outer grating (3), the outer side of which forms the curved surface of the bobbin (1), the curved surface serving as a supporting surface for the strands. The bobbin (1) includes means (2, 2', 2", 3, 4, 5) which retain the grating (3) when the bobbin (1) is not compressed more than a predetermined length in the axial direction in such a manner that the outer surface is positioned in a radial outer position, and which release the grating (3) when the bobbin (1) is axially compressed more than a predetermined length in such a manner that the outer surface is inwardly displaceable into a radial inner position, and which prevent an additional inward displacement of the outer surface.

Abstract: A rigid core for a textile yarn package particularly for dyeing is cylindrical in shape, corrugated over the whole outer peripheral surface corresponding to the package, and has a part situated at one end which is provided with a groove, incorporating perforations of a maximum diameter of 2 millimeters, which is intended for forming a yarn reserve, a central part perforated with tapered orifices, wider at the outer surface than the inner, with an angle of taper, relative to the axis of the respective orifice, being between 2.degree. and 80.degree., preferably between 20.degree. and 70.degree., and two interengably shaped ends to permit the fluid-tight nesting of the cores on each other during the dyeing.The method of using such a yarn package in which a textured continuous polyester yarn is reeled at a speed of between 400 and 1,000 m/min.

Abstract: The disclosure concerns a non-thermal expanding spool for use in oxidation of green spun carbon fibers, subsequent to fiber spinning and prior to carbonization. The spool is a hollow tube formed on a mandrel from a multi-ply, multi-directional woven graphite cloth impregnated with a thermosetting resin, e.g. polyimide. Then a plurality of hoop fiber filaments are wrapped around it which also become impregnated with the thermosetting resin. The resulting tube or spool is then baked or cured at elevated temperatures. The baked spool is then provided with a large number of geometrically or randomly disposed holes or openings.

Abstract: Take-up bobbin arrangement in which a compressible plastic yarn dye tube is secured onto a yarn take-up bobbin by an end cap which is secured to the bobbin by detents. The end cap has a reciprocating locking member which prevents the yarn being wound onto the dye tube from pushing the end cap out of the bobbin but at the same time allows ready removal of same without yarn damage. The yarn wound on the compressible yarn tube can be readily slid off the bobbin and used directly in the dye cycle for the yarn.

Abstract: A process for the level exhaust dyeing of polyester fiber textile material is accomplished by dissolving unfinished disperse dyestuff synthesis material in as high a concentration as possible in an organic solvent miscible with water. This solution is forced into an aqueous liquor already at a dyeing temperature of 90.degree. to 140.degree. C. and already circulating through the polyester fiber textile material. Dyeing of the material then occurs in the usual manner.

The coil carrier comprises a supporting member and a sliding member axially displaceable relatively thereto, the external diameters of the supporting and sliding members being substantially equal.

Abstract: A tube for yarn bobbins of a moulded plastic material which may be axially compressed, said tube being composed of a number of connected concentric rings (2), where the two end rings (1 and 3) are differently shaped with inner and outer cylindrical surfaces (4 and 6) or conical surfaces adapted to each other, said surfaces providing a seal, and where the cylindrical or conical surface is formed by arms (9) extending from the rings along generatrixes, and the rings are connected with strings (11) shaped as springs which when stretched extend substantially parallel to the generatrixes but which are located under the cylindrical or conical surface formed by the arms.

Abstract: A coil carrier for packages of thread or yarn comprises interconnected carrier elements extending parallel to its axis. The individual carrier elements (1; 25; 40) are circumferentially compressible and shape-retaining coupling members (4, 7; 10; 15; 29, 30 to 33) are provided between adjacent carrier elements. The gap between two adjacent carrier elements is larger than the dimension of a carrier element in the circumferential direction.

Abstract: A method and apparatus for dyeing of yarn in package yarn form wherein a yarn package of a given initial density is compressed axially to a second density and thereafter a metered quantity of a yarn treating agent is introduced into selected portions of the package followed by a diffusing fluid introduced into the said selected portions to diffuse the yarn treating agent into selected portions of the package.

Abstract: The invention relates to a lap creel made of rod shaped carrying members (1) which form, together with ring shaped fixing elements (2-6) a circular cage. The carrying members (1) project radially outwardly across a portion of the fixing elements (2-6). A fixing element (2) arranged at one end of the lap creel, has inwardly opening grooves (10), the number of which corresponds to the number of carrying members (1). Through these means the appropriate end of the lap creel receives a free-space inner cross-section which corresponds to the outer cross-section of the opposite end of the lap creel. The outer surfaces (7) of the carrying members (1) form parts of a shell which is shaped so that an imaginary enveloping of the lap creel in the central region has a contraction (8). The lap creel thus receives a bi-conical shape; that is, a shape which occurs if two truncated cones at the smaller of the end face diameters are arranged end to end.

Abstract: A resiliently compressible bobbin comprising two end rings disposed opposite to one another in a spaced relationship, a plurality of transverse ring frames distributed equidistantly between and in parallel with the end rings and a plurality of straight longitudinal frames interconnecting the end rings and distributed equidistantly around the periphery of the bobbin. The longitudinal frames each have a thickness gradient decreasing radially outwardly, are flush with the end ring's inner and outer peripheral surfaces and are constructed so that portions on opposite sides of a transverse ring frame are gradually increased in thickness toward the transverse ring frame in the same direction, but in opposite directions relative to the portions on opposite sides of the adjacently disposed transverse ring frame, the midportion between transverse ring frames being narrowed.

Abstract: To liquid-treat filamentary materials, such as threads, yarns and textiles, a hollow package of the filamentary material is confined within a vessel so that the package subdivides the interior of the vessel in an inner and a separate outer chamber which communicate with one another only through the thickness of the filamentary material. A foamable treating liquid in unfoamed state is admitted into one of the chambers and is pressed into the filamentary material in order to wet the filamentary material with the liquid. The still unfoamed liquid is then discharged from said one chamber and a pressurized gaseous fluid is forced through the package in order to evenly distribute the wetting liquid throughout the package and to foam it at the same time.
