Roland,
Rotating the tube on the thread break sensor works sometimes with some
situations but not all.
First, the thread break sensor is a hollow tube basically suspended over the
top of 2 very small rubbery compound ball bearings that sit in small sockets to
retain them. Spinning the tube aggressivly could cause these balls to be
rotated out of their sockets and that would not be a good thing.
Also at both ends and inside of the sensor tube are extremely sensitive
crystals that react to pressure. As material thickness increases, the thread
will be pulled up tighter against the sensor tube and this will send a signal
to feed more thread on the next down stroke. As the material thickness
decreases, a signal will be sent to reduce thread feed on the next down stroke
of the take up lever.
Now, rotation of the tube....the rubber ball bearing may take on a flat sided
shape over time because of constant pressure and always being in one position
in it's socket. Gently rotating the tube can reposition the ball to a slightly
different position creating a different pressure situation for the crystal to
react to....over simplfied but that is how it is suppose to work....
Work environment, heat, long term non-use of the machine, dirt, dust, lint
buildup, water, cable problems, connectors/connecions, PC boards....lots of
other reasons it sometimes will not function properly.....sometimes replacement
is the only solution...
