An apparatus for manipulating a material is provided. The apparatus may comprise a magnetic device arranged in a three-dimensional configuration. The apparatus may comprise a surface on which at least one carrier is configured to move. The magnetic device may be configured to provide a magnetic field for driving the carrier on the surface to manipulate a material. The apparatus may comprise a controller configured to control the magnetic device to modulate the magnetic field. The controller may be further configured to detect a position and/or motion of the carrier.

An apparatus for manipulating a material is provided. The apparatus may comprise one or more stator coils arranged in a three-dimensional configuration, and a surface on which at least one carrier is configured to move. The stator coils of the apparatus may be configured to generate an electromagnetic field for driving the carrier on the surface to manipulate a material.

A braiding system having a plurality of mobile carrier devices movable under its own power, each mobile carrier including a plurality of wheels, a motor driving the wheels, a power source, a controller, and a pick-up unit having a receiver. Each of the plurality of mobile carriers has a tow carrier positioned in the receiver, and each mobile carrier is simultaneously movable along a virtual track-less path predetermined for each individual carrier, such that the simultaneous movement of the mobile carrier devices along their predetermined paths form a braid.

A braider comprises a plurality of horngears. The horngears can be arranged for forming at least two closed paths for braiding. Each horngear has a driving gear and a hornplate. Each horngear can be selectably operated in a first mode, to rotate with the driving gear, and in a second mode, in which the driving gear rotates, but the hornplate does not. Bobbin carriers are positioned on some of the horngears. A track is configurable in: a first flat braiding mode with the carriers arranged on the horngears, so that there is one or more separate closed path for forming a first flat braid configuration; and a second flat braiding mode for forming a second flat braid configuration different from the first flat braid configuration. A switch is provided for changing a configuration of the track between the first and second flat braiding modes.

A braider has a track for guiding 4N bobbin carriers and 4N horngears, where N is an integer greater than one. The horngears each have four horns for forming at least two paths. The bobbin carriers are positioned on the horngears in a tubular braiding mode with the track and horngears configured to provide two paths intersecting each other, to form a tubular braid section. The bobbin carriers are positioned on the horngears in a flat braiding mode, with the track and horngears configured so that there are N separate closed paths that do not intersect each other, to form a flat braid section. The braider is switched between the tubular and flat braiding modes while N of the horngears are free of contact with the bobbin carriers, to form a continuous braid having at least one tubular braid section and at least one flat braid section.

An apparatus is disclosed for braiding fine denier yarns to form a braided suture product which includes a frame, and a main carrier support plate supported on the frame and having a pair of undulating guide channels intersecting each other for guiding a plurality of yarn carriers. A plurality of yarn carriers are supported on the main carrier support plate, and each supports a bobbin for dispensing fine denier yarn. The yarn carriers are directed over intersecting paths corresponding to the shape of the guide channels, with a first set of the carriers being directed in a first direction and a second set of the carriers being directed in the opposite direction. The yarns are received in a common braiding zone above the yarn carriers while the yarn carriers are directed through the intersecting paths of the guide channels to form a braided sheath from the yarns. The tension of the final braided product is controlled within predetermined ranges to permit formation of a braided product of predetermined appearance. A method of producing the braided product on the inventive braiding apparatus is also disclosed.

The bobbins in a jacquard-type lace-making machine are displaceable by means of mechanisms each constituted as an output member carrying one or two bobbins, a transmission member and a continuously rotating drive member. The drive and output members are formed with respective bevel gears centered on the axis of the device and the transmission member carries at least one bevel gear rotatable about an axis transverse to the rotation axis for the mechanism and meshing with both of the gears so that the output gear can rotate in a direction opposite that of the drive gear. An operating shaft carries a pair of operating arms and is displaceable between a stopping position in which the one arm arrests the output member while the other arm allows the transmission member to rotate and a racking position in which the one arm allows the output member to rotate whereas the other arm arrests the transmission member. A cam may be provided on the drive member or on the output member for forceably returning the operator to the stopping position after 180.degree. displacement of the output member.
摘要:
A machine for braiding wire, yarn or other filaments around a common axis, comprising a first plurality of wire bobbins in an annular array which dispense yarn to the central axis and which array moves in one direction about the axis and a second plurality of wire bobbins in a radially more inward annular array, and each of which dispenses wire to a wire guide that delivers wire to the central axis; the second bobbins and the wire guides move together in the opposite direction around the first bobbins; each wire guide selectively shifts between a position radially outwardly of the first wire bobbins and radially inwardly of the first wire bobbins; the radial shifting motion of the guide means is between alternate first wire bobbins; means for radially shifting the wire guides to coordinate their radial movement with the relative movements of the first wire bobbins.

Systems and methods are provided for braiding Metal Matrix composite (MMC) tape. One method includes drawing multiple lanes of MMC tape, comprising a matrix of metal reinforced by fibers, from bobbins arranged around a mandrel. The method also includes braiding the multiple lanes to form a preform at the mandrel for an MMC part and consolidating the preform via application of heat and pressure.
