6. WELD IS RELEASED; HEAD RETURNS TO
HOME POSITION.
The hot-knife retracts and the welding clamp
pushes the two molten surfaces together,
welding the strap.
After this short delay, to ensure that the strap
has fused properly, the camshaft again turns
and the holding gripper, the welding clamp
and the end gripper retract to the neutral
position.
The anvil then retracts and the welded strap
is released to the lower side of the package
The camshaft returns to the home position
and closes LS3 and LS5. The
electromagnetic clutch is de-energized by
LS3 while LS5 energizes SOL1. As the
solenoid pulls down on the tensioning lever,
the feed rollers close against the strap,
pushing it through the head and out into the
strap channel. The feed timer de-energizes
and SOL1 is released.
Strap feed stops and the machine is ready
for the next cycle.
NOTE: SOL1 ENERGIZES TO CLOSE
FEED ROLLERS AND FEED STRAP
AFTER THE CAM SHAFT REACHES
