Slitter Rewinder Technology - Auto Laser Core 

The part that they don't show you: You physically take a tape measure and go from a fixed and consistent point on the drive side of the machine to where the edge of the web actually falls upon the core. Then, you slide the bare core onto your rewind shaft to that precise measurement. Then, align your laser with the edge of that bare core. Easy

You program it in the computer you tell it what size jumbo you have on back or "the unwind side" then you program the size cuts you want in the front or "rewind side" and that's how the laser knows where to set each core on the front

@@brentlucas2211 is it a waste of time you have to pull 6 ft before you start the machine still

I was expecting the cores to line up automatically 🤷

@@jmkglass2356 It's surprising in this day and age that they aren't aligned automatically, from what I've found. These are usually small companies, and need the customer (with deeper pockets) to fund R&D to align the cores automatically. Unfortunately, it takes good leadership on the customer side to initiate such a thing. Factory workers are not always open to automation, since it removes some of their workload. Whenever a luddite gives me crap for being an automation engineer, I ask them, "Are you willing to discard your washer/dryer and do all your laundry by hand?" They always say, "no". Good leadership is hard to find these days.

Judging from the way you spell and compose your sentences: I'm sure you're not a good one.

Some places are doing it with lasers, but that is still in the 20th century.

As someone who has ran this machine the marker would keep wearing off and you have to keep measuring and remarking
