  I used to work and maintain one of those transmitters... I mean seam sealers.  

  A "Tent and Awning" company in Tulsa asked me to come out and look at their splicer.  I was saying, "what????"   Well, I was a consulting engineer and decided to go look.  This was in the 80's.  When I got there I found basically an AM transmitter that caused enough RF in the BIG BAR that was several feet long, that it melted the plastic, or whatever materials, together.  I fixed the transmitter and it worked.  
  I have to admit that this was, at first thought, strange.  But it turned out to be "simple"..... A transmitter to splice material together???? oh well.......

  Live and learn...

My sister and her husband own and tent/awning shop. They use a number of RF seemers to melt the vinyl canvas together. The two pieces of vinyl are smashed between two aluminum bars about 18" long. The bars serve as part of the capacitance in the tank circuit (I think). I look at their machinery and see some pretty heavy duty parts that would easily make a multi-kW rig.
