The specific embodiment

Below in conjunction with accompanying drawing and by embodiment the present invention is further described:

A kind of loom 3 (shown in Figure 3) includes heald frame 32, reed 31, shuttle 2, it is characterized in that: outer rim (Fig. 3 of warp thread 41 ends before being woven into cloth 4, shown in 2) be provided with track 1, the track profile is made up of two sheet frames 11, the two ends of this two sheet frames lower edge link to each other with pivot pin 12, the microscler notch 13 (shown in Figure 1) of the middle part of this track lower edge for supplying cloth to pass through, the relative inner face place of this two sheet frame respectively is provided with the two magnetic row that are parallel to each other, permanent magnet 14 in every magnetic row is uniformly at intervals, be provided with the bare electromagnet 15 at place, sensible sheet frame two ends between these two magnetic row, between the outer rim of warp thread end and the angle between track two sheet frames be the V-arrangement (Fig. 2 that is close respectively, shown in 3), in track, move, the shuttle 2 (shown in Figure 1) that the bottom is V-shaped, its dual-side 21 with the corresponding section of the set magnetic of sheet frame row and bare electromagnet position, also each is provided with the two magnetic row (permanent magnet 22 in every magnetic row also is accordingly uniformly at intervals) and a bar permanent magnet 23 of the permanent magnet with identical polar.

Also can be between the top and reed of two sheet frames of described track, each connects a rotating connecting rod 33 (shown in Figure 1).Also can respectively establish the pendulum that can swing 24 at the two ends at described shuttle top, the bottom of this pendulum is provided with wears groove 241.Also can outside the two ends of described track, respectively establish a start stop apparatus 16 (shown in Figure 6), this start stop apparatus has the pedestal 163 (shown in Figure 7) of the near v-shaped track 1631 of a shape and shuttle bottom connection, two medial surfaces of this v-shaped track be provided with shuttle on two magnetic row and the corresponding electromagnet in a bare electromagnet position (electromagnet that is in every row accordingly uniformly at intervals is 162, and bare electromagnet is 1621).

Because the row of the magnetic on the shuttle are classified identical polar as with the corresponding magnetic on the sheet frame, be suspended in the track by the effect shuttle of magnetic repulsion, during the loom operation, make the bare electromagnet energising on track two sheet frames, and the identical polarity of bar permanent magnet of generation and corresponding section, shuttle both sides, thereby produce magnetic repulsion and shuttle moved along the track friction free of doing to float, so according to this magnetic repulsion effect and shuttle is moved back and forth in track at high speed.When the heald frame on the loom that warp thread is staggered, when shuttle is finished hook wefting insertion yarn to loom one side, reed along the slippage of warp thread down direction with the push-tight weft yarn, and the drive of mat connecting rod and make the two sheet frames swing of track open (position shown in the double dot dash line among Fig. 2), and when reed returns back to original position, make track two sheet frames return back to the V-arrangement angle position that originally is again, thereby make shuttle can do continuous moving back and forth.The pendulum at two ends, shuttle top can be adjusted automatically with air-flow thrust and be flapped toward, the pendulum that (shown in Figure 4) is positioned at left end when shuttle moves left tilts to be a specific angle, the pendulum that is positioned at right-hand member is then uprightly to a specific angle, the air flow stream of operation is crossed the pendulum of left end and is produced a thrust that presses down, and afterflow passes and makes the pressure balance before and after the shuttle more help operating steadily of shuttle to the pendulum of right-hand member and via the groove of wearing of its underpart, when shuttle moves to the right (shown in Figure 5), in like manner also operate steadily, thereby the stability that makes shuttle move back and forth at a high speed further improves.
