moving at least one of the bobbins on the active track past the bobbin moved to the passive track; and
returning the bobbin on the passive track to the active track, wherein the bobbins moving along the active track are in a different sequence,
the strands being braided into one pattern when the bobbins are in the one sequence and into a different pattern when the bobbins are in the different sequence.
5. The method of claim 1 wherein the passive track is inside the active track.
6. The method of claim 1 wherein:
moving the plurality of bobbins along the active track comprises moving at least some of the bobbins along a first oscillating path and moving at least some of the bobbins along a second oscillating path, the first oscillating path being out-of-phase with the second oscillating path.
7. The method of claim 6 wherein:
selectively moving the bobbin to the passive track comprises moving the bobbins to a non-oscillating path.
8. A method of making a surgical braid, the method comprising:
moving a plurality of bobbins along an active track, the active track being an endless track;
selectively moving a bobbin to a passive track while continuing to move the remaining bobbins along the active track;
shifting a gate from a closed position to an open position before selectively moving the bobbin to a passive track; and
shifting a gate from an open position to a closed position after selectively moving the bobbin to a passive track.
9. A method of making a surgical braid, the method comprising:
moving a plurality of bobbins along an active track, the active track being an endless track;
selectively moving a bobbin to a passive track while continuing to move the remaining bobbins along the active track;
the bobbin moved to the passive track carries a colored strand, the bobbin being a first bobbin; and
the method further comprising moving at least a second bobbin from the plurality of bobbins past the passive track while the first bobbin is still on the passive track.
10. The method of claim 9 further comprising:
moving the first bobbin back onto the active track.
11. A method of making a surgical braid, the method comprising:
moving a plurality of bobbins along an active track, the active track being an endless track;
selectively moving a bobbin to a passive track while continuing to move the remaining bobbins along the active track; and
moving a second bobbin onto a second passive track.
12. A method of making a surgical braid, the method comprising:
moving a plurality of bobbins along an active track, the active track being endless track;
selectively moving a bobbin to a passive track while continuing to move the remaining bobbins along the active track;
the bobbin selectively moved to a passive track is a first bobbin and carries a strand having a first color; and
the method further comprises selectively moving a second bobbin to a passive track, the second bobbin carrying a second color.
13. The method of claim 12 wherein:
selectively moving the first bobbin to a passive track and selectively moving the second bobbin to a passive track comprises selectively moving the first and second bobbins to different passive tracks.
14. A method of making a surgical braid, the method comprising:
moving a plurality of bobbins along an active track, the active track being an endless track;
selectively moving a bobbin to a passive track while continuing to move the remaining bobbins along the active track;
wherein the bobbin selectively moved to a passive track is a first bobbin and carries a strand having a first color;
moving the first bobbin from the passive track to the active track and selectively moving a second bobbin to a second passive track, the second bobbin carrying a second color; and
wherein none of the bobbins on the active track are moved past the passive track before the acts of moving the first bobbin from the passive track to the active track and selectively moving the second bobbin to the second passive track.
15. The method of claim 14 wherein:
the active track is an endless track, and the active track goes around the passive track.
16. A method of making a surgical braid, the method comprising:
moving a plurality of bobbins along an active track, the active track being an endless track;
selectively moving a bobbin to a passive track while continuing to move the remaining bobbins along the active track;
the plurality of bobbins moving along the active track comprising a determined number of bobbins arranged in a first sequence; and
selectively moving the bobbin from the passive track to the active track to form a second sequence of bobbins moving along the active track, the second sequence of bobbins being different than the first sequence of bobbins.
17. The method of claim 16 wherein:
each of the bobbins carries a strand and each of the strands has a color; and
the strand on the bobbin moved to the passive track has a different color than at least one of the strands on the bobbins continuing to move along the active track.
18. The method of claim 17 wherein the colors are selected from the group consisting essentially of blue, green, violet, brown, purple, black, white, and combinations thereof.
19. A method of making a surgical braid further comprising:
moving a plurality of bobbins along an active track, the active track being an endless track;
selectively moving a bobbin to a passive track while continuing to move the remaining bobbins along the active track;
the plurality of bobbins moving along the active track comprising a determined number of bobbins arranged in a first sequence;
each of the bobbins carrying a strand and each of the strands has a color, and the strand on the bobbin moved to the passive track has a different color than at least one of the strands on the bobbins continuing to move along the active track;
selectively returning the bobbin from the passive track to the active track to form a second sequence of bobbins on the active track, and
the surgical braid being braided when the bobbins on the active track are in the first sequence has a different color pattern than the surgical braid being braided when the bobbins on the active track are in the second sequence.
20. A method of making a surgical braid the method comprising:
moving a plurality of bobbins along an active track, the active track being an endless track;
selectively moving a bobbin to a passive track while continuing to move the remaining bobbins along the active track;
each of the bobbins carrying a strand; and
braiding the strands carried on the bobbins moving along the active track around the strand from the bobbin moved to the passive track, the strand carried by the bobbin on the passive track forming a core for the surgical braid.
21. The method of claim 20 wherein:
selectively moving a bobbin to the passive track comprises returning a different bobbin from the passive track to the active track.
22. The method of claim 21 wherein:
each of the bobbins carries a strand and each of the strands has a color; and
the strand on the bobbin moved to the passive track has a different color than at least one of the strands on the bobbins continuing to move along the active track.
23. A method of making a surgical braid, the method comprising:
moving a plurality of bobbins along an active track, the active track forming an endless path for the bobbins, each of the bobbins carrying a strand and each of the strands having a color, the plurality of bobbins moving along an active track comprising a determined number of bobbins arranged in one sequence;
selectively moving a bobbin to a passive track while continuing to move the remaining bobbins along the active track, the passive track being outside the endless path, the strand on the bobbin moved to the passive track having a different color than at least one of the strands on the bobbins continuing to move along the active track;
moving at least one of the bobbins on the active track past the bobbin moved to the passive track;
returning the bobbin on the passive track to the active track, the bobbins moving along the active track being in another sequence different than the one sequence; and
