After the cool off time has expired, strap release will be initiated. The camshaft rotates from
position 7 into point 8. Gripper, loop grip and vibrator move backwards to its home point 8.
The camshaft rotates from point 8 without stopping into position 9. The shutter starts opening
(sensor "Shutter close" will be de-activated) and is in fully open position at position 9 (sensor
"Shutter open" is occupied and sensor “Pre-tension reached” will be de-activated again). The
"Camshaft brake" Y38 will be activated and holds the camshaft in position until next step
"Shutter close" will be activated. At the same time the large clutch Y22 ("slow speed") de-
energises and the motor M24 rotates in idle position.
At this point, the head is moved away from the package, releasing the strap from the sealing
mechanism until limit switch "Head back to home position" (machine installation) is activated.
Next step; "Shutter close" is activated. The camshaft rotates now from position 9 into position 0.
Hereby the "strap drive brake" Y36 is activated and the camshaft brake Y38 de-activated. At the
same time the large clutch Y22 is activated.
Before reaching position 0, the sensor "Strap tension reached" will be de-activated again and
that time the large clutch Y22, motor M24 and the strap drive brake Y36 have to be deactivated.
The camshaft brake Y38 has to be activated and stops the camshaft in position 0. The camshaft
rests in position 0 and the shutter is closed. Is the sensor “shutter close” activated also, the
head is in home position and ready for further application.
