Free top is the term used to describe the distance between the
top edge of the unfolded bag and the top surface of the product
in the bag. (

) For best results, the PBC 6000
requires a free top of 6 inches (153 mm) for standard size folds
and greater than 6 inches for wider folds. Using a shorter free
top may cause the bag to bulge and be torn by the shrouds.
6.5 SPEED CHECKS AND SYNCHRONIZATION
Synchronizing the PBC 6000 involves adjusting external and internal rates to provide a good
strong seal. The external synchronization is between the machine and the conveyor system. The
carry through belts of the PBC provide the machine speed for folding and sealing the bag top.
