In use, first determine whether to weave super wide cut or the heavier parallel of fiber, fixing if not disassemblingSupport column 73 on frame 7, reclaims support bar 72, then by fixed rotating shaft 71, fixed mount 7 is forwarded to a side of frame 1,Guard box 79 in fixed mount 7 upper covers. Super wide cut or the heavier parallel of fiber if weave, lift fixed mount 7,Make fixed mount 7 fixing with frame 1 by support bar 72, and locked fixed rotating shaft 71, then allow fixing by support column 73Frame 7 support column ground. Determine at high-speed cylinder 9 travelling carriage 77 on effect lower support bar 72 past according to the actual requirement of weavingMultiple speed, and regulate the magnetic force of electromagnet 64 on the position of air track 61 two ends moving sliders 63 and moving slider 63Size is determined the reciprocal speed of sliding part 8. Change the position of photoelectricity door 66 simultaneously by fixing hole 62, make to detect accurately.Because parallel flying speed is very fast, specially adopt two-stage to move back and forth, travelling carriage 77 also can be moved with respect to fixed mount 7,The reaction susceptibility that improves air-guide rod 81, makes the speed of air-guide rod 81 can catch up with flying in special-shaped reed 4 end parallels completelyLine speed. Now because of travelling carriage 77 and all high-speed motions of sliding part 8, if occur that in motion process some deviations willHave influence on the air guide effect in special-shaped reed 4, also specially on fixed mount 7, offer two direction recess 74 for this reason, allow movementThe direction that platform 77 can only limit at direction recess 74 by roller 78 moves and there will not be left and right skew, again by positive stop strip 75Limit the upper and lower vibrations of travelling carriage 77, made travelling carriage 77 there will not be skew up and down.
