Extend EXS-206 - HOLDING GRIPPER RISE AND HOT-KNIFE ACTION

4. HOLDING GRIPPER RISES; HOT-KNIFE
MOVES INWARD. Momentarily electron
tension detector energizes the control circuit to
energize the electromagnetic clutch and turn
the cam shaft. As the cam shaft turns, the
holding gripper rises to contain the other end
of the strap beneath the anvil. The tension
lever is lowered to release tension and the
welding clamp begins to rise.
It’s important to note that all tension to the
strap must be released before the strap is cut,
otherwise the strap-end could be damaged
and feeding reliability will be affected. The
hot-knife moves in between the two layers of
strap.
NOTE: TENSION ROLLERS
ARE RELEASED AND STRAP
IS AT REST.
