Doboy JSL (Header Label Applicator & Sealer)

Discontinued in 2015; The Doboy JSL used hot jaws and a unique mechanism to simultaneously fold / apply a header label and seal small bags.  It could also punch a hanger hole & emboss lot/date code on your bag - all in one step!

The JSL was an excellent way to automate operations where header labels were previously being manually applied and sealed or stapled.

If you own a JSL that's worn but not yet dead, contact us about Syntegon's JSL Remanufacturing Program.
