Ensure it is parallel to the front plate by slowly pushing it against the front plate. Readjust the
nuts on the rear channel as required.
Note: Pressure bar adjustment should only be necessary after rod or bushing replacement.
4.10 Drive Belt Tension Adjustment
The T-1000 has two belts, one of which will periodically require adjustment. The drive belts
(Fig. 4-18) will require adjustment if it becomes loose during normal operation.
Turn the power to the OFF position and unplug the power cord. Remove the right cover and
inspect the tension of the belt by pressing down on the belt between the drive pulleys. The belt
should flex approximately 1/4". If the belt appears too loose, loosen the screw which is fastened
to the drive belt tension assembly and push bearing tightly against the belt. Tighten the screw
and test the tension. If sufficient, replace the cover, plug in the power cord, and turn on the
T-1000. Note: If the belt "chatters", it is too tight.
4.11 Sealer Cylinder Adjustment
Two "speed controls" operate the speed of the cylinder in and out motion that brings the pressure
bar against the front plate (gripper plate). Increasing the speed of the pressure will increase
production. But, if the pressure bar moves in or out too fast causing the pressure bar to "bang",
excessive wear will occur. The valve which controls the pressure bar cylinder is located on the
main center cylinder on the inner frame (Fig. 4-19). The adjustment knob (B) controls the speed
of the pressure bar INWARD (towards the front plate). The adjustment knob (A) controls the
speed of the pressure bar OUTWARD (away from the front plate). To decrease the speed of the
pressure bar INWARD, turn the knob (B) counter clockwise. To decrease the speed of the
pressure bar INWARD, turn the knob (B) clockwise. To increase the speed of the pressure bar
OUTWARD, turn the knob (A) counter clockwise. To decrease the speed of the pressure bar
OUTWARD, turn the knob (A) clockwise. Adjust the speed of the pressure bar so that it moves
in and out rapidly, in a fluid manner, without causing the pressure bar to "bang" in or out.
4.12 Pressure Bar (Rubber) Replacement
Located along the inside of the pressure bar is a strip of rubber, held on the pressure bar by a
channel, pressing on the edges of the rubber. The rubber compresses against the front (gripper)
plate holding the bag in place during sealing and during bag tear off. If the rubber becomes
brittle, torn, gouged, or otherwise worn, it should be replaced to assure strong seals.
To replace the pressure bar rubber, simply pull one end of the rubber from the channel. The
rubber will come out of the channel quickly and easily. To install a fresh piece of rubber, press
one edge of the rubber into the channel then the other edge. Work the rubber into the channel in
small increments along the length of the channel (Fig. 4-20). If you used PTFE Anti-Stick tape to
cover the surface of the rubber, place the PTFE Anti-Stick on the rubber along its length. If the
PTFE Anti-Stick extends beyond the rubber, cut off the excess.
Note: PTFE Anti-Stick may be added to the pressure bar rubber if the bag sticks to the rubber
after loading and sealing. The bag may stick to the rubber if the product and bag is light in
weight and if the rubber is dirty.
Note: Frequently clean the rubber with alcohol to remove buildup of dirt or other contaminants.
