TIP 030-0403 External Girth Glue Sealing From The Top

This upgrade is part of the Technical Improvement Program (TIP); it converts the machine from internal glue sealing or external from the bottom to external glue sealing from the top.

A new external girth glue gun is assembled prior to the feednip rollers. The gear rack is used to position the glue gun to achieve the desired stripe position on the wrapping sheet. As the sheet starts to feed, the glue gun is activated along with the cooling air gun. The cooling air gun is critical to the process to decrease the glue temperature prior to going into the feednip to ensure no contamination. Once the ream is wrapped, the girth seal conveyor reheats the glue as the ream goes through it and seals the ream shut.
