Thank you mike,
I admit it's a bit confusing to watch!

Hi Mikey,
It is a moderate speed (adjustable 15-45 pkgs minute) pvc overwrap machine used in the meat and vegetable packaging industries
Chances are that you have eaten food that has been packed on one of the many machines i service!

Oh, okay, I get it. I watched the video twice and couldn't imagine what it did but now that you enlightened me, I can see how it works. I assume the two blades that come in from the sides are heated to seal the package.

Thanks, Mike - learned something new today!

Hi Mikey,
thanks for your interest.
the 2 blades that come in from the sides are folders, they are responsible for folding and tucking the film in on the sides if the package.
there is a (brown) teflon belt that runs over a 1200watt heating plate, heated to 125*C, that fuses the film on the bottom side of the package and prevents unwrap

Now that you've figured that out watch the knotters on a square baler.



The guy that invented that knotter carved his prototype out of wood.

Amazing! You can almost see how the inventor must have approached this - okay, this gets the twine here and now I need to twist it to form the knot ... form follows function and you have the next piece in the train. Fascinating!

Thank you, John and Mike

Oh, okay. That makes even more sense.

I installed the retrofitted machine into its new home yesterday, at a facility 4 hours south of my office.
here's a picture of the machine on the trailer ready for the trip.
sc delivery.jpg
the installation was uneventful, the retrofit worked as expected.
there were some mechanical production adjustments that took an hour to complete.
but as you can see the package looks great!
the foam tray is a 9L,
dimensions without product:
12.13" long X 9.25" wide X .75" tall
(this package was a sample and not intended for consumption)

sc sample package.jpg

with product this tray can exceed 5" height for roasts and other large cuts

thanks for your interest :)

The most amazing thing about those knotters is how robust and forgiving they are (at least the New Holland ones. IH knotters not so much).

Nice work Mike.
-brino
Thank you very much Brino!
i really try to do good work, it's nice when things work out .
the customer goes back to full production, and my immediate emergency ends :grin big:

He really is a true Doctor! I've often wondered why he used this handle.
CHuck the Grunpy old Guy
Thank You Chuck!
the machines are very well built but have some pretty complicated electrical control systems.
this machine was the equivalent of comatose upon arrival, the customer wanted a 2 week process scrunched into less than 5 days :cautious:
