I am a master machine adjuster SOS my 4# runs at 650bpm bags per minute #8 at 550. These slow ass foreign machines make me laugh. Buy a Potevin or B and R.
I am a lead man who works on many paper bag machines and the fastest I've ever seen ran 250 bpm you say 650 bpm I'd love to see the machines your running those type of speeds and still able to make good bags
