KNIFE ACTION
The knife, as illustrated in the photograph, catches
any fingers that have been pushed forward by the
solenoid. It is VERY IMPORTANT that the knife is in
the lower position before you start weaving (first
selection)
When you raise the knife with the front handle
or the left treadle, the magnet (see page 7 picture),
which is glued to the back of the knife, passes in
front of two magnetic sensors. As it passes the top
sensor, the solenoids
will release.
As you complete this pick, by closing the shed
completely (handle in the uppermost position or right
treadle pushed down completely) the magnet will
pass by the lower sensor and cause the pattern to
advance one pick and then actuate the solenoids for
the new pick.
The magnetic sensors are mounted in a slot
behind the fingers. The sensors have been adjusted
and glued in place before shipping. The position is
marked on the block that the sensors are mounted
on. Small adjustments can be made, but be careful,
the sensors are very delicate.
Both the sensors and the magnet work only on
one side. If the magnet must be replace do a test first
and reverse if necessary.
Sensors
One pick sequence
a) Start Pattern (software). The solenoids
activate, pushing the fingers forward.
b) As the knife moves up, the fingers are
caught by the knife and the solenoids are
then released.
C) After the pick is woven and the shed
closed, the next pick is made.
Down system function
There is a time out after 60 seconds of no activity.
To continue weaving, you will have to stop and
start your sequence in the loom control of your
software.
