1.4 How to Remove/Reinstall the P-tension Shaft for
Easier New Fabric Weaving
At the new fabric weaving, removing top cross rail
1, back roller 5, and P-tension shaft 6makes it eas-
ier to set the reed, heald frames, and droppers to
the weaving machine.
(1) Remove bolts 3from right and left clamps 2on
top cross rail 1.
NOTE: Do not loosen or remove bolts 4.
(2) Take out back roller 5.
(3) Make a note of the mounting angle of the leaf
spring, and then loosen bolts 8on coupling 7.
(4) Slide the coupling 7in the direction of arrow A.
(5) Remove bolts 10 from holder 9and take off the
holder.
(6) Remove P-tension shaft 6.
(7) Set the reed, heald frames, and droppers to
the weaving machine.
(8) Put P-tension shaft 6on the bracket.
(9) Fit coupling 7onto P-tension shaft 6until cou-
pling 7comes into contact with the stop ring,
while pressing shaft 6in the direction of arrow
Aand sliding coupling 7in the direction of
arrow B.
(10) Hold the leaf spring at an angle recorded in (3)
and secure coupling 7with bolts 8.
(11) Secure holder 9with bolts 10.
(12) Place back roller 5.
(13) Put top cross rail 1on the bracket.
(14) Tighten bolts 3.
(15)
After start of new fabric weaving, set the pile ten-
sion. Then loosen bolts
8
on coupling
7
and
adjust the angle of the P-tension roller again so
that the warp sheet at section “
C”
becomes
almost horizontal.
(16) Check that bolts 3, 4, 8, and 10 are tightened
to the specified torques.
The reed, heald frames and droppers are very
heavy, so take extra care when handling them.
In (16), tighten bolts to the torque values spec-
ified in the Standard Machine “Instruction Man-
ual,” Chap. M, Subsect. M.1.9.
