3.1.1
Mounting the Warp Beam(s) and
Procuring Warp Yarn
[ 1 ] Mounting a single beam
•
When two or more workers are to handle a
job, they must always communicate through
words or gestures before starting the job.
•
When handling warp beams, their flanges
and gears, take extra care. They are
HEAVY.
Step
Work Procedure
(1)
[At the warp beam gear side]
Determine distance L1 according to warp beam
flange diameter 2a and warp beam diameter 1b
by referring to the table below.
(2)
Make a mark on warp beam 1 "L1" mm away
from its left end 1a with a felt pen or something
similar.
NOTE:
Refer to the submitted drawing for
detailed dimensions.
(3)
Screw-in warp beam flange 2 over warp beam 1 in
the direction of “A” until the flange’s inside
becomes aligned with the mark made in step (2).
•
For making the screwing-in job easier, apply
grease or oil to the threaded section.
