The camshaft rotates from position 5 to position 7 and the next step, welding will be initiated.
Thereby the vibrator support moves forward with the cutter blade and vibrator.
(see drwg. 464655, pos. 9, 22, 25, Page 39).
At point 6 the sensor "Pre-tension reached" will be de-activated again. With this switching point
the weld motor will be started, and via the eccentric drive of the vibrator the weld oscillation will
be reached. First the cutter blade cuts off the strap end under no load and the vibrator presses
both straps oscillating on top of another. The oscillation process melts both layers of strap
together. Depending on the strap quality the programme sequence is set (approx. 0, 5 sec) and
the weld motor stops. The strap ends will be combined by the motionless vibrator. At position 7
the camshaft stops as long as the cool off time is set in the programme sequence
(
approx.
3
sec.
), so the melted joint is able to cool off under pressure.
