Energizing Seal Band Time Adjustment
Note:
The Energizing Seal Band Time Adjustment has been set at
the Eastey facility and should not have to be changed. See the
information below for adjustment if needed.
The Energizing Seal Band Time is the amount of time that the seal
band will be energized when in the cutting position. The energizing
time is set by a small timer located on the surface of the shrink
tunnel base under the sealer above the lower fan grille. The
“Energizing Time” timer should be set to a value less than the seal
time. Depending on film properties, such as material, thickness,
and run rate, the energizing timer may need to be adjusted in small
increments to attain optimal seal.
Caution!
Make very small changes to the energizing time value. High
energizing times may overstress and burn out the seal band.
Sealing the Product
Advance the film across the product tray. Remember the film is split with the bottom half
going beneath the product tray and to top going over the product tray.
Note:
For best results, the seal head should be cycled three to four
times initially before sealing to warm up the upper seal head.
Pull a short length of film into the seal area and pull the seal bar down to create a lead
seal.
Lift the top film and place the product to be sealed on the product table under the top
layer of film.
Advance the product and film to the seal area on the take away conveyor.
Close the sealing bar using slight pressure and let go. The sealing bar will seal the
product and release automatically according to the sealing time setting.
After the seal head has been released the take away conveyor will move the product
into the shrink tunnel.
Repeat for the next package to be sealed.
As products are moved through the case sealing machine a long tail of scrap will
accumulate on the operator side of the machine. Wind the scrap material around the
two fixed holders.
