6. Use Loctite
®
222 on the screw threads, (
D
) to mount the new pulleys on the bottom of the
compression sprocket. Be sure the Loctite has completely cured before using the machine.
7. Place the carry through belt back on the pulley and turn the tension bolt, until the desired
tension is achieved. A belt with the proper tension will deflect between ½ to ¾ inch (13 to 19
mm), when pulled from the middle of the belt with a reasonable force. (

8. Tighten the top and bottom holding bolts for the infeed to keep the carry through belt at the
desired tension.
9. Install the fixed and swing channel shrouds.
10. Turn “ON” the electrical and pneumatic supplies to the PBC 6000. Check the pulleys for
proper functioning.
DRIVE SPROCKET – COMPRESSION BELT
The compression belt of the PBC 6000 is driven by a toothed sprocket (
Illustration 8.18
) for
accurate timing. The sprocket should not need to be replaced unless it becomes damaged.
Replacing the sprocket should only be done by a trained technician. If the sprocket needs to be
replaced, please contact your Fischbein representative.
8.5.6 CREASER WHEEL
The creaser wheel of the PBC 6000 is responsible for forming a crease in the bag top to form the
fold. The creaser assembly is divided into two main parts, one on the fixed channel and one on the
swing channel. The swing channel portion forms the inside of the folded crease with a blade-type
wheel. The fixed channel portion forms the top of the fold by using a grooved (die) roller that
receives the creaser blade. (
