Abstract: Systems and methods for forming a tubular braid are disclosed here-in. A braiding system configured in accordance with embodiments of the present technology can include, for example, an upper drive unit, a lower drive unit, a mandrel coaxial with the upper and lower drive units, and a plurality of tubes extending between the upper drive unit and the lower drive unit. Each tube can be configured to receive individual filaments for forming the tubular braid, and the upper and lower drive units can act in synchronization to move the tubes (and the filaments contained within those tubes) in three distinct motions: (i) radially inward toward a central axis, (ii) radially outward away from the central axis, and (iii) rotationally about the central axis, to cross the filaments over and under one another to form the tubular braid on the mandrel.

Abstract: A braiding apparatus includes a platform, a base plate, a core unit, a transmission unit, a track assembly, and strand carriers. The track assembly is divided into two braiding track groups each provided with transmission discs. The transmission discs of both braiding track groups are sequentially connected to define two braiding routes. The strand carriers shuttle on both braiding routes respectively and incessantly. Two intersection points are defined when the two braiding routes intersect. Accordingly, carrier strands fed by the strand carriers are wound around a core strand fed by the core unit while shuttling incessantly and are interwoven with each other while passing through the two intersection points during the incessant shuttling motion, thereby wrapping a multi-convolutional braided layer around the core strand to complete a rope. Each convolution of the braided layer has two crossing points, which increases the practicability of the rope.

Abstract: A string, rope, or strap with repetitively spaced openings/flexible eyelets from bifurcated braiding or weaving, or from cutting and sealing. The bifurcated openings are preferably created from a single rope or strap that is subsequently braided or weaved into two strings, ropes, or straps and then back into one. The frequent and periodic placement of these eyelets on the string, rope, or strap, allows the user to easily tie down items. The rope or strap is flexible enough to pull it in on its self, through its eyelets. The ends of the string, rope, or strap are finished into a hard tip.

So, the various braids with constant interval of perforations are possibly produced by differ the number of core yarns and carriers.

Abstract: A machine, for the construction of a braid (11), that includes a set of identical multiindented wheels (2), which are mounted on a fixed support (1) and driven in rotation to cause the circulation of spindles (6) carrying spools (7) of braiding threads (8). The multiindented wheels are disposed in parallel and equidistant lines (L—L). In the set of multiindented wheels: the multindented wheels (2) belonging to a line are spaced from one another, so that two consecutive multiindented wheels belonging to one and the same line cannot cooperate directly with one another; and a multiindented wheel (2) belonging to one line is disposed between two multiindented wheels belonging to an adjacent line and cooperates with the two multiindented wheels, In the spaces between the consecutive multiindented wheels of a line, there are provided passages (3) for the longitudinal elongate elements (9) of the braided tubular structure.

Abstract: A fabric forming device including a stationary yarn supply and a rotating yarn supply, each delivering yarn to a common point along a vertical axis where they are interlaced. The stationary yarn supply includes a plurality of yarn carrying cones which are arranged along a common horizontal plane about the vertical axis. The rotating yarn supply includes a plurality of yarn spools mounted with a rotating plate about the vertical axis. A plurality of vertically moveable guide members which are adapted to engage with the yarns of the rotating yarn supply act to selectively alter the horizontal path along which the yarns travel. The guide members act to control the yarns of the rotating yarn supply to be selectively positioned to pass above or below the cones carrying the stationary yarns so that the yarns interlace in a desired manner.

Abstract: A machine for three-dimensional braiding of fibers is provided in which carrier members travel on a curved, segmented and movable braiding surface. The carrier members are capable of independent, self-propelled motion along the braiding surface. Carrier member position on the braiding surface is controlled and monitored by computer. Also disclosed is a yarn take-up device capable of maintaining tension in the braiding fiber.

Abstract: A braided reinforcement for tubular conduits such as hose, and a method and apparatus for producing such reinforcement are disclosed. The reinforcement is characterized by a three over, three under braid pattern. The apparatus comprises as Maypole type braider wherein each driver of the braider includes six pockets to accommodate carrier spindles, and the number of carriers is three times the number of drivers. The invention provides an improved braided product which can be produced at lower cost with increased output.

Abstract: A mechanism for timing strand movement relative to rotation of holders or carriers for strand supply spools or bobbins, being rotated in opposite directions by the drive mechanism of a braiding machine. The drive mechanism is mounted around a stationary shaft extending from a frame member. The mechanism includes an adjustable actuator means carried by the frame member radially of the stationary shaft and housng a selectively rotatable control shaft carrying a first sprocket. A second sprocket connected to the first sprocket by a chain means is connected to a journal sleeve around the stationary shaft. The journal sleeve carries a circular control element. The control element carries either a series of passive deflector cam plates for yarn strands or a cam track for a series of positive wire strand guiding mechanisms. There is also an improved drive mechanism for a braiding machine having a rotating table for carrying a set of outer spool holders.

Abstract: A method for the formation of a three-dimensional woven fabric comprises causing arms of carriers disposed around one component yarns out of three mutually perpendicular component yarns and having the other two component yarns separately held thereon to be rotated, opposing carrier arms of adjacent carriers to each other thereby effecting transfer of yarns, and successively effecting said transfer of yarns to carrier arms of the subsequent carriers thereby enabling the two component yarns to be displaced and zigzagged relative to the remaining one component yarn. An apparatus for effecting the aforementioned method essentially comprises a multiplicity of carriers arrayed longitudinally and laterally on a carrier holding plate and means for imparting necessary movements to the carriers. The three-dimensional woven fabric can be formed in a desired shape or yarn arrangement by suitably varying the pattern of arrangement of the two component yarns.
