3.1.4
Preparing the Reed and Drawing in Warp
The reed plays a very important part in the machine operating efficiency and fabric quality. When handling the
reed, observe the following precautions:
–
Unpacking
•
Unpack the carton containing the reed on
the workbench or the like.
–
Drawing-in
•
Draw in warps through the center of dents
to prevent the dents from becoming dam-
aged.
•
Take care not to damage or bend the dents
with the drawing-in tool.
–
Transportation
•
Cover the reed with cloth or corrugated
cardboard to protect it from damage during
transportation.
–
In operation
•
If a warp is broken when the machine is in
operation, draw a warp through section “A”
(not in section “B”) of the dents as shown at
left.
Use the reed whose lower jaw portion does not interfere with the range specified in the upper figure.
If the reed lower jaw portion is within the specified range, damage by contact with the feeler or feeler malfunc-
tion may arise. Refer to the submitted drawing for details.
[ 1 ] Drawing-in width
The tables below list the nominal reed spaces and effective drawing-in widths.
NOTE:
For twin beams
Reed space: 280, 336, 340, 360 and 390, Min.
drawing-in width: (Nominal reed space – 70 cm)
IMPORTANT
Check whether you are responsible for the preparation of the reed. If you are responsible, prepare it before
the start-up to weaving.
