Not surprising to see a Marquip roll splicer in the video. There were huge take up rolls that would move in to give slack while the splice occurred. The line never slowed down and was moving at 50-60 mph. They were the industry leader when I worked there from 96 to 98 while going to tech school in Madison. I worked in the electronics department functionally testing the boards that controlled the machines. Testing the control boards for the slitter/scorer machine got interesting at times. If there was a bad control card the heads would slam together or shake violently. Always had my hand on the e-stop during that test. Had to stand on a switch mat for it to work otherwise the interlock was active. Those heads moved so fast if you got caught while it was moving you would need to be squeegeed off the floor.

They also built their own 480V 3 phase VFD drives that were liquid cooled. Each test station for the VFD drives had a 6’ long wooden cane by it incase a test operator touched the wrong part of the board and you had to pull the burning carcass off without yourself getting electrocuted. Each station had 1/2 thick clear polycarbonate shield incase the IGBT blew you wouldn’t get taken out by shrapnel. When they blew it sounded like a 12ga shotgun went off. Always kept a fresh pair of undies in the locker. I’ve had holes burned through my shirt with sparks that escaped between the cracks in the shield when parts blew up during test. Never a dull moment there.

About a year after I left there they closed the Madison plant and moved everything to Phillips WI.
