ntroduction:
The Weft Sensor is highly sophisticated and reliable device to
sense the weft breakages, and
uneven weft tension in Circular
Loom.
It
operates
on
the
principle of magnetism and
hence does not malfunction due
to effect of dust and ambient
light which are invariably present
on any loom. The sensor does
not require any maintenance like
cleaning, adjustment, setting etc.
and will give years of trouble
free service. Periodic checking of
magnet holders is required.
Packing List :
After receipt of
material, check for all items as
indicated in ’Packing List’.
Installation:
The installation is very easy and can be done by anyone having
fair knowledge of Loom. First fit the magnetic reflector assembly on shuttle
boom pipe. lf original reflector assemblies are already there then you may be
able to use them. Ensure that these assemblies are at equal distance from ring
and nearest to ring. Next, fix the sensor in the clamp provided. Put an
universal joint on bolt of the clamp and mount the universal joint on pipe where
a photo sensor may have used earlier.
Suggested connections of magnetic sensor to avoid gapping
problem after weft Break:
In mechanical loom, the Take-up Roller (Haul-off)
rotates through mechanical link from main shaft rotation. When weft tape
breaks, one tape goes missing from fabric and hence the take up must be
stopped immediately after weft break. Because, after STOP signal is
generated, the loom actually takes few rotations before stopping completely.
