摘要： Methods of braiding using a braiding mechanism are described. The braiding mechanism includes an array of filament engagement elements, a mandrel extending from the center of the circular array, a plurality of actuators disposed operably about the array, and a rotating mechanism adapted to rotate one or more filaments. The plurality of filaments are loaded onto the mandrel by looping a middle portion of each filament of the plurality of filaments over an end of the mandrel and extend radially toward and contact the circumferential edge of the circular array of filament engagement elements. The plurality of actuators are operated to engage a first subset of the plurality of filaments and move the engaged filaments in a generally radial direction to a position beyond the circumferential edge of the array. The rotating mechanism is operated to move the engaged filaments about the mandrel axis.

摘要： Methods for forming a tubular braid are described. The method for braiding includes providing a braiding mechanism including a disc, a mandrel, and a plurality of actuators. The disc defines a plane and a circumferential edge and the mandrel extends from a center of the disc. A plurality of filaments are loaded on the mandrel, each extending radially toward the circumferential edge and contacting the disc at a point of engagement. The plurality of actuators are operated to engage and move a first subset of filaments in a generally radial direction to a position beyond the circumferential edge. The disc or the engaged first subset are rotated relative to one another, thereby crossing the first subset over a second subset of filaments. The actuators are then operated to move the first subset to a radial position on the circumferential edge different from its previous point of engagement.

摘要： Methods of braiding using a braiding mechanism are described. The braiding mechanism includes a disc defining a plane and a circumferential edge, a mandrel extending from a center of the disc that is adapted to hold a plurality of filaments extending radially from the mandrel toward the circumferential edge of the disc, a plurality of catch mechanisms positioned circumferentially around the edge of the disc, a plurality of actuators adapted to move the plurality of catch mechanisms in a substantially radial direction relative to the circumferential edge of the disc, and a plurality of filaments extending radially from the mandrel towards circumferential edge of the disc. A middle portion of each filament of the plurality of filaments contacts an end of the mandrel.

摘要： Mechanisms and methods for forming a tubular braid are described. The mechanism for braiding includes a disc, a mandrel, a plurality of catch mechanisms, a plurality of actuators, and a computer program. The disc defines a plane and a circumferential edge. The mandrel extends from a center of the disc and is adapted to hold a plurality of filaments extending radially from the mandrel toward the circumferential edge of the disc. The plurality of catch mechanisms are positioned circumferentially around the edge of the disc and are adapted to engage a filament. The plurality of actuators are configured to move relative to one another and are adapted to move the plurality of catch mechanisms in a substantially radial direction relative to the circumferential edge of the disc.

摘要： Methods of braiding using a braiding mechanism are described. The braiding machine includes first and second annular members, the second annular member being concentric with the first annular member. A mandrel extends perpendicularly to and intersects a horizontal plane defined by a substantially circular region of the second annular member substantially at the center of the circular region. Each of the annular members has a plurality of tubular guide wires slideably mounted thereon and a plurality of wires extend from the mandrel through each of the tubular wire guides. The first annular member rotates circumferentially relative to the second annular member. The first plurality of tubular wire guides slides radially inward to align with the second annular member, and the second plurality of tubular wire guides slides radially outward so as to align with the first annular member.
