[4] How to Remove/Reinstall the P-tension Shaft forEasier
New Fabric Weaving
At the new fabric weaving, removing top cross rail 1, back roller 5, and P-tension shaft 6 makes it easier to set the reed,
heald frames, and droppers to the weaving machine.
The reed, heald frames and droppers are very heavy, so take extra care when handling them.
In (16), tighten bolts to the torque values specified in the Standard Machine “Instruction Manual,”
Chap. M, Subsect. M.1.9.
(1) Remove bolts 3 from right and left clamps 2 on top
cross rail 1.
NOTE
: Do not loosen or remove bolts 4.
(2) Take out deflection roller 5.
(3) Make a note of the mounting angle of the leaf
spring, and then loosen bolts 8 on coupling 7.
(4) Slide the coupling 7 in the direction of arrow A.
(5) Remove bolts 10 from holder 9 and 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 6 on the bracket.
(9) Fit coupling 7 onto P-tension shaft 6 until coupling 7
comes into contact with the stop ring, while pressing
shaft 6 in the direction of arrow A and sliding
coupling 7 in the direction of arrow B.
(10) Hold the leaf spring at an angle recorded in (3) and
secure coupling 7 with bolts 8.
(11) Secure holder 9 with bolts 10.
(12) Place deflection roller 5.
(13) Put top cross rail 1 on the bracket.
(14) Tighten bolts 3.
(15) After start of new fabric weaving, set the pile
tension. 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.
CAUTION
Clean the pile yarn contact part on the board
panel and the guide bar at every beam
change, and confirm that no foreign sub-
stance is attached. (This is to avoid a thread
being adhered by a substance such as paste
that adversely affects and tension.)
