Seal Point; Seal Time; Reverse; Blow Off - Advanced Poly-Packaging Advanced Poly-Bagger T-1000-S14 Operation Manuals

Typical setting for Air Pulse is 0.2 seconds for smaller bags and 0.4 seconds for larger bags. If the index
speed is lower (6-15"/Sec), the Air Pulse may need to be longer.

3.10 Seal Point

Seal point is measured from the top of the bag and can be set to the desired or required location.
The proper positioning of the seal on the bag varies due to bag size and product characteristics. Wider
bags or bulky products require greater sealing area. Typical settings for Seal Point: .8 inches for
narrower bags, 1.2" mid-size widths and 1.5" for wide bags.
<New Bag> button is used to start an internal program which calculates an average bag length.
The perf is used for registration. If a perforation is not detected, the bag will stop in the correct
seal position based on the average bag length measurement. A Feed Error message will be
displayed if the perf is not detected within a range of acceptance of bag length.

3.11 Seal Time

Seal Time is the time the heater bar comes in contact with the rubber strip, which is mounted on the
pressure bar. Seal time is one of three critical components to obtain a good quality seal. Other critical
factors include seal temperature and seal pressure. After adjusting Seal Time, test for good seals and
adjust if necessary.
Typical settings for Seal Time with temperature set to 400 degrees F: 0.3 seconds for thinner bags (1.5
mil), 0.4 seconds for medium thicknesses (2 to 3 mil) and .7 for heavier thicknesses (4 mil). However,
the set temperature will affect the required seal time. If adjusting pressure or temperature, test various
seal times until satisfied with the seal quality.

3.12 Reverse

The distance the bag reverses can be set to cause the perforation to break between the bags. For wider
bags, the reverse distance may need to be increased. A typical setting is 1".

3.13 Blow Off

A blow off tube is provided to decrease the possibility of bags sticking to the Teflon. Increase the blow
off time if bags are not falling from the machine. Typically, the blow off time is set to .15 to .25 seconds.

3.14 Index Speed

Bag feeding (index) speed can be set to improve production. If bags are prematurely breaking at the
perforation, reduce the index speed. For shorter bags, the speed can be significantly decreased (to
10"/Sec, for instance). The typical setting is between 15 and 25" per second.

3.15 Seal Temperature

Electrical current is pulsed to the heater element to maintain a constant temperature. Waiting LED is
displayed if the temperature is not within the set range. The typical temperature is setting is between 360
and 440 degrees depending on film thickness.
