Abstract: A process and apparatus for laying highly ordered webs wherein a fibrous strand forwarded towards a collecting surface is caused to oscillate up to an amplitude equal to the desired web width and by passing between two closely spaced plates is laid in successive courses with a very high degree of parallelism and precision. A plurality of the laying devices may be used to produce thicker or wider webs or webs having layers of differing orientation directions. Various bonding methods may be applied to the ordered webs.

Abstract: Filament cables of denier above 10,000 dtex are produced by operating several continuous melt spinning-stretching processes at production speeds above 3,000 m/min, to form several continuously spun and stretched filament bundles, which bundles are then continuously plied and deposited in the form of a cable.The process among others is useful for high speed production of filament cables of nylon-6 with improved breaking strength and/or breaking extension.

Abstract: An improved apparatus for taking up textured yarn plugs into a cartridge is provided. The apparatus comprises a spiral-walled cartridge and means for rotating the cartridge about a vertical axis while moving it laterally. In operation, the cartridge is rotated beneath a yarn texturizer as textured yarn in plug form is deposited therein in orderly layers. Even with high-speed texturizers, cartridge speed is low. After the plugs have been deposited, the cartridge may be removed, and the yarn plugs may be pulled out for knitting or weaving.

Abstract: A simplified mechanism is provided for imparting motion to a frame member connected to the lower ends of a number of yarn conducting tubes so that the lower end of each tube moves in a circular path to dispense yarn in the form of a coil. A single horizontal motor driven shaft drives a worm gear which, through a gear reduction, drives crank arms connected to the frame member. A supporting box is provided mounted independently of the horizontal shaft for mounting the worm gear and gear reducers, allowing free access to those structures. The sole accessory components connected to the frame member are the yarn tubes and the crank arms.

Abstract: An apparatus is disclosed by which ropes and similar elongated objects can be accumulated in storage cans. The object is advanced through an upright stationary upstream guide tube and through a rotating downstream guide tube and its discharging end distant from the axis of rotation. A braking drum coaxially surrounds the orbiting trajectory of the discharging end of the downstream guide tube so that the portions of the objects which are being discharged through the discharging end impinge against the inner surface of the braking drum. The inner surface of the braking drum is arched, such as partly circular or partly parabolical in axial section and the objects rebound therefrom at an angle corresponding to the angle of incidence of the object on the inner surface. The downstream guide tube has a cross section exceeding that of the upstream guide tube. A ceramic annular element is arranged at the lower end of the upstream guide tube.

Abstract: An annularly segmented generally cylindrical pick-up container is disclosed for use in combination with bounce crimping apparatus which texturizes a multi-filament yarn of synthetic resinous material. The container includes a plurality of annular baffles which divide the container into a corresponding plurality of substantially annular chambers. The container is rotated while a texturized multi-filament yarn of synthetic resinous material is deposited into the annular chambers. As one chamber becomes full, the rotational axis of the container is moved to a new position so that the texturized material will begin filling the next radially outwardly adjacent annular chamber.

Abstract: A yarn severing and holding apparatus for use in a system for changing spinning cans in which synthetic filamentary yarns are deposited. In this apparatus an arm supported, independently of the can transporting means, for rotation at a level between the yarn feeding device and the cans, has a slide mounted thereon for traversing movement lengthwise of the arm. This slide carries a cutting device and also a device for clamping the severed end of the yarn deposited in the full can. This insures that the cut off end of the yarn cannot drop back into the full can and that on the other hand the free end can drop into the still empty can immediately after the cutting operation. Moreover, the severing and holding apparatus is physically divorced from the can-transporting means so that the latter may be designed for either rotational or translational movement.

Abstract: Disclosed is an apparatus for producing a compact package of a textile yarn, comprising an accumulation container disposed to a machine frame in a rotatable condition about a longitudinal axis thereof, an inlet of a textile yarn formed at a position above said accumulation container in an eccentric condition to said longitudinal axis of said accumulation container, a compression means provided with a pressing head capable of being inserted into said accumulation container. Said pressing head is capable of reciprocally displacing up and down along said longitudinal axis of said accumulation container in such a condition that the working position of said pressing head is eccentric from said longitudinal axis of said accumulation container.

Abstract: An apparatus for depositing a continuous strand of material into a container includes a rotatable elbow-shaped tubular member having a substantially vertical portion and an angled portion. One end of a tubular sleeve is rotatably mounted on the angled portion of the elbow member, and the other end of the sleeve being free. The sleeve has an assymetric, substantially V-shaped slot which divergingly extends from an intermediate portion of the sleeve to the free end thereof. Means for rotating the elbow member and sleeve member about the vertical axis of the elbow member and simultaneously rotating the sleeve member about its own longitudinal axis are provided such that the material is deposited in concentric circles of varying radii as the material is selectively delivered from a different portion of the sleeve's V-shaped slot.

Abstract: Method for the take-up of continuous filament bundles of synthetic fibers at a high speed, which comprises introducing the continuous filament bundles discharged from an air jetting device and carried on the air stream into a bent tube provided downstream from the air jetting device, which is rotating in substantially reverse direction to that of the continuous filament bundles discharged from the outlet of the bent tube at a peripheral speed of the outlet thereof being 0.5 to 2.0 times the take-up speed of the continuous filament bundles (e.g. 2,000 to 6,000 m/min.), and receiving the continuous filament bundles into a receiving device provided downstream of the bent tube, and an apparatus useful for the take-up of the continuous filament bundles.
