Abstract: A thread guide construction for use in the production of twisted threads. The thread guide is composed of a plate arranged essentially horizontally and having at least three guide eyes arranged symmetrically to one another for a separate guiding of the threads which are to be twisted. A separating member is secured to the underside of the plate between and symmetrical to the guide eyes. The separating member has a width which is less than the spacing between the guide eyes and has a surface thereon converging from the plate toward a terminal location spaced from the plate. The surface is opposed to each of the guide eyes so that when a pulling force is applied to the twisted threads during a twisting operation pulling same away from the plate, the threads are normally free of engagement with the separating member and are in engagement with the surface during a time when the pulling force has been substantially reduced.

Abstract: A tube for insertion into a coil of flexible material wound in a series of figure-8s with a radial opening extending into the axial opening through which the inner end of the material can be drawn out without twist has a flange spaced from its free end and a second flange adjacent the free end with the space between the two flanges being substantially equal to the wall thickness of a container in which the packaged coil is to be enclosed.The outer flange is interrupted at two points and has an outwardly bent portion. The tube is inserted from the outside into the radial opening of the coil, which is then placed inside the container with the outer end of the tube directed towards an opening in the container, which has notches therein. Upon turning the tube, the outwardly bent portions ride up on the wall of the container, so that the tube can be turned to a position in which the principal part of the outer flange engages against the outside of the wall.

Abstract: Package winding of textile strands uninterrupted by transfer from a full to an empty package is accomplished by delaying lateral transfer of the winding strand from a full to an empty package and by picking up a resulting transfer tail of the laterally transferring strand adjacent the end of the empty package. The transfer delay step utilizes a bistable inertial device located to intercept the laterally transferring strand and to be repositioned thereby and to release the strand after momentary inertia-induced delay during which the strand begins to wind onto the empty package. The pickup step utilizes rotary devices located at the spaced adjacent ends of spindles for the respective packages, such device on the spindle of the package to which the strand is transferring being adapted to engage and grip it. The strand is broken or otherwise severed between the pickup device and the full package, thereby enabling the strand to be traversed onto the empty package.

Abstract: A gathering shoe is disclosed for combining glass filaments which have been attenuated from a bushing into a consolidated strand. The gathering shoe is formed of a porous material, preferably porous graphite, and has a central chamber or cavity within which is located gaseous fluid jets connected to a gaseous fluid supply. As gaseous fluid is forced through a slot in the porous shoe over which the glass filaments are combined into a unitary strand, the glass fiber strand rides on a gaseous fluid cushion. This decreases wear of the shoe and breakouts of the filaments caused by such wear and aids in drying the glass filaments.

Abstract: It has been suggested that synthetic multifilamentary yarns can be produced by melt-spinning a polyamide or polyester polymer under conditions of substantially simultaneous spinning and drawing wherein prior to said drawing the filaments of the fiber are lubricated with a spin finish by surface contact with a lube roll surface of not less than about 90 RMS. However, in commercial operation of the process at high throughput rates of 50 pounds per hour or greater through the spinneret, serious problems have been encountered due to "flicking" or momentary slackness of one or more filaments from the main yarn bundle above the lube roll, which flicking results in production of yarn of relatively poor quality. It has now been found that the occurrence of said flicking of the filaments can be greatly reduced by applying the spin finish from a convergence guide having a yarn-lubricating surface of not less than about 10 RMS and means for distributing a film of lubricant over said surface.

Abstract: A pinch ring for the thread balloon of a spinning machine or twisting machine is substantially a single wire loop forming a spiral or helix. The ring may have overlapping end portions. The degree of overlap and the shape of the overlapping end portions as well as the pitch and the axial clearance between opposite points in the overlapping portions are all critical to the performance of the ring. The pinch ring defined by the invention permits substantially higher production rates without decreasing the rupture strength of the thread and provides a thread with substantially higher strength at standard production speeds.

Abstract: This invention relates to a balloon control ring.Said balloon control ring has, on its inner surface of the ring proper, a plurarity of ribs arranged in parallel at regular intervals. The ribs are also arranged in such a manner that a yarn contacts the ribs at an angle against the direction of the ribs. The ribs successively overlap each other so that a yarn contacts at the same time the point at which it leaves one rib and the point at which it comes into contact with the next rib. Said balloon control ring proper is fixed to a supporting means which is fixed to the frame of a machine.Thus the balloon control ring can control ballooning of yarns satisfactorily in the spinning doubling and twisting process and the like of an artificial or synthetic fiber or a mixture of fibers, while allowing a yarn to pass through at a high speed without causing melting, fluffing or breaking of the yarn.

Abstract: A winding machine in which incident to the production of a bobbin a thread reserve is built up axially adjacent to the bobbin. The machine has a traversing thread guide with a thread-guiding slot and with slanted side faces, and an auxiliary thread guide with an arm which extends into the thread traversal plane at an angle pointing in the direction of the thread reserve zone. The arm is moved, generally rectilinearly and parallel to the path of the traversing thread guide, so as to lift the thread out of the slot of the traversing thread guide when the latter moves, in the direction away from the thread reserve zone, against the auxiliary thread guide. Passing of the thread between the two guides is facilitated by making the two side faces of the traversing thread guide of different lengths. The disclosed design is of particular advantage where a waste winding is to be built up in the principal winding range prior to the formation of the reserve winding.
