    Abstract: A method and apparatus for forming bulky yarn is disclosed wherein fibrous filaments, attenuated at a high velocity, are wrapped and tangled about a continuous fibrous strand by means of introducing the filaments into an inverted open cone rotating at high velocity, countercurrent to the flow of a fibrous strand introduced simultaneously into the open cone.

    Abstract: A method and apparatus for reducing the tension of continuous glass fiber strand is disclosed. The apparatus is composed of a traveling surface rotating about an axis. The surface has a plurality of tracks of variable lengths running oblique to the axis of rotation of the surface. The termination point of the track on the traveling surface is also the point of origin of a subsequent track, thus a continuous irregular path is defined by the tracks. The tracks are determined by a plurality of contact points on which the glass fiber strand engages. The surface travels at a slightly greater linear speed than the take-up winder thus reducing the tension of the strand on the glass fiber strand package. Additionally, the surface may be reciprocally traversed the length of the take-up package or alternatively the take-up package can be traversed to obtain a random wind of glass fiber strand.

    Abstract: Textile material to be dried is passed through a heated tubular element in a generally longitudinal direction. Means are provided to impart lateral movement to the textile during its passage through the tubular element to prevent sticking to the walls of the tube. Means to heat the tubular element, retrieve the textile material and to introduce air countercurrent to the longitudinal direction of the textile path are shown. The use of apparatus employing a plurality of tubular elements and a common air manifold to feed each element is also disclosed.

    Abstract: Forming packages of glass fiber strand containing a substantially uniform thickness of wound strand are provided by oscillating the strand and winding the oscillated strand in a plurality of superimposed layers on a rotating cylindrical surface bounded by axially-spaced surfaces that extend outward from the strand-collecting surface in gradually-diverging relationship. The ends of the package are formed by winding the strand against the diverging surfaces each time a layer of strand is completed. After winding, the gradually-diverging surfaces are removed to provide a forming package having substantially cylindrical inner and outer surfaces and end surfaces which extend outward in gradually-diverging relationship from the inner surface of the package. The forming package, when dried, is selfsupporting. A plurality of these forming packages are horizontally disposed in rows supported one above the other with the lower rows supporting the upper rows to provide a supply of a plurality of individual strands which are withdrawn from the interiors of the packages and further processed.

    Abstract: Crimped fibers in novel form are described in which mats of fiber are provided which are characterized by having the fibers interlocked in both horizontal and vertical directions. A method of preparing such fiber glass mats is described and involves attenuating a plurality of fibers in spaced parallel relationship at extremely high speeds and projecting them onto a collecting surface while they are traveling at high rates of speed to interrupt the flow of fibers and produce by this interruption a plurality of bends in the fibers as they are being collected. The high inertial force inherent in the fibers traveling at high speeds as they strike the collection surface imparts to the fibers a novel crimping action. By collecting a multiplicity of layers of fibers produced in this manner fiber glass mats are produced which have a needled appearance with the glass fibers constituting the mat being interlocked in a multiplicity of directions as well as in the horizontal and vertical plane. Methods of producing these fiber glass mats on collect type winders as well as on continuous belt mat surfaces are described.

    Abstract: Textile material such as strand, yarn, or cord is simultaneously false twisted and impregnated while in a slack (low-tension) condition by feeding the textile material in slack condition into one end of a rotating cylinder containing the coating and withdrawing it from the other end. The textile material in untwisted form and the coating are held against the interior of the rotating cylinder by centrifugal force and the coating impregnates the textile material while subjected to such force. The impregnated textile material passes through a heated tube to dry the coating on the textile material. A uniformly coated twisted textile material wrapped in low tension on a takeup package is produced.
