Oh yes, seen most everything. Have pictures too. Call me for a possible remedy.
So Joe calls me and says he must watch the baseball game and call me in the morning.
Here is the remedy I would have suggested to Joe:
First thing to insure safety of the rug, don't tug on it excessively. Get some dehumidification going into the cylinder or an air mover at minimum for a few hours. Maybe a day. When the rug dehydrates a bit, it will begin to implode off the cylinder just a bit. This will allow you to insert two 10' - 12' boards in between the rug and cylinder wall the full length in. This will likely take patience and a bit of time so as not hurt the rug. Be careful! Position them on top at 11 and 2 o'clock. Next roll the cylinder 180 degrees so the boards are carrying the weight of the rug in the position of 4 and 7 o'clock. Now gently pull the boards out like a field stretcher carrying a body that is injured on the battle field. The rug should follow.
The last time I stuck one in was last week. I put an Indo-Persian, 6 X 9, into my small 6 foot centrifuge. I even back rolled it for a test of our machines ability. The rug layered so many times it had NO center opening in the middle. The cylinder was a packed in with a wet rug all the way to the back of the cylinder! It extracted wonderfully. But the rug was stuck for two days. I air dried it and used two hockey sticks and proceeded as outlined above. Success occurred again with the stretcher technique.
Now I am done telling on myself for tonight.
