  • Patent number: 8066035
    Abstract: A bead stringing apparatus that enables the user to quickly restring pre-strung beads, of the type that are on temporary strings, commonly available in bead stores. The connectors on the apparatus pull both ends of the temporary string in a taut position over an open work space. This aligns the pre-strung beads automatically along the temporary string allowing them to be restrung easily by a permanent string or wire. The user can quickly resting rows of the pre-strung beads by putting their wire through the aligned holes and when the wire exits a row of the pre-strung beads the user can add in other loose beads on their wire to go in and between the pre-strung beads. This allows the user to create infinite designs and patterns of beadwork. The open work space around the pre-strung beads provides flexibility and ample room for the newly incorporated loose beads to hang down onto the permanent wire out of the way of the beading process.

  • Patent number: 7909066
    Abstract: Two layered beads (B) arranged between two neighboring warps (tx-1) and (tx) are woven by inserting a weft (yx) through center holes (2) of the beads in (B) in a forward direction or in a backward direction and turning the weft (yx), around one of the warps (t). A two layered beaded fabric is obtained by repeating the movements of the weft (yx). A three layered beaded fabric can be obtained in the same manner as the two layered beaded fabric.

  • Patent number: 7677273
    Abstract: The beading loom with a removable warp thread cartridge has warp threads mounted in a cartridge that is removably received in a frame of the loom, allowing the user to bead the threads in a conventional manner, but without having to wrap the threads on the loom manually. Once finished with one beading product, the user may then remove the cartridge from the loom and replace the beaded project with a fresh cartridge of warp threads. The frame has an elongated base having an adjustable length along the longitudinal direction.
