3. PREPARATIONS FOR WEAVING START-UP
76
[ 2 ] Mounting twin beams
(For LH beam)
NOTE:
At the RH side of the let-off motion, install the
RH beam in the same manner as for the LH beam.
Step
Work Procedure
(1)
[Opposite to the warp beam gear side]
Set center flange 6 onto warp beam 7 and set
center flange ring 5 so that bolt holes provided
in ring 5 become aligned with those in flange 6
and beam 7.
(2)
Secure ring 5 to beam 7 with six bolts. Then,
align bolt holes in flange 6 with those in ring 5
and tighten four bolts.
(3)
[At the warp beam gear side]
Install side flange 4, beam gear 2, and beam
gear ring 8 onto warp beam 7 as shown at left.
Bolts 1 and 3 should be temporarily tightened.
(4)
Turn beam gear 2 by hand so that the distance
from the end of center flange ring 5 to the
machined inside end of gear 2 comes to (Draw-
ing-in width
÷
2 + 50) mm, then secure gear 2
with bolts 1.
(5)
Turn side flange 4 by hand so that the inside
end of center flange 6 to that of flange 4 comes
to (Drawing-in width
÷
2 – 55) mm, then secure
flange 4 with bolts 3.

beam 7
Four bolts which secure ring 5 to
