Mattress Size Adjustments
The 1390BX machine is designed to automatically detect and adjust itself for one of the three basic bed
lengths: 75”, 80” and 84”. To detect the bed length, the machine uses two arrays of three proximity
sensors which are mounted on rectangular guide rails. One array is mounted on the left side of the Input
frame, under the table, near the front of the machine (right illustration). The sensors detect the position
of the (left) movable Input frame during the bed alignment and locating cycle. Depending on how many
sensors are covered in this array, the machine controller determines how long the bed is and how far to
move the adjustable Output Seal Bar frame assembly. This assembly uses the second array to get it
positioned for the subsequent sealing process. The Output array is located near the left access door under
the movable Seal bar frame (left illustration). It is adjusted to ensure that the opening between the two
Side Seal bars is about 1” greater than the length of the bed detected in the Input end of the machine, to
prevent bed jamming during the transfer from Input, to the Output side of the machine.
Before this machine is shipped, it is adjusted and tested according the customer bed specifications and
should not need to be readjusted. If the parameters of the bed change after installation and it is necessary
to readjust these arrays, it is very easy to do so. Simply loosen the screw that clamps the proximity
sensor mounting block and move in the desired direction. If you want to be able to detect a smaller bed
in the Input, move the sensor toward the center of the machine and vice versa. It works the same way if
you want to stop the adjustable Output Seal bar frame.
Maintenance
Under normal operating circumstances, the 1390B machine does not require much maintenance. The
following list outlines the normal machine maintenance that should be performed on periodic bases to
keep the machine in a good working order:
Daily
Clean the three Seal bars at least once a day, preferably at the beginning of the first shift, before the seal
bars begin to heat up. To clean the Seal bars, use a soft cloth and WD-40 as the solvent. Use extra
caution and make sure Seal bars are not hot or heating up before cleaning. Also, use extra care not to
scratch the Seal bar’s anti-stick coating. If the coating surface is scratched to the bare metal, the plastic
film may stick to it, which in turn may result in poor seal quality and /or machine down time.
Visually inspect PTFE tape (covering the lower seal bars) for any cuts and delaminating from the lower
seal bar. If necessary, replace the tape.
