Backing wear thru

[Bill C @ Fineline]

Is it common for the backing to wear a hole in it at the back of the hoop where it rubs on the arm of a XT? It also leaves a black build up on the arm if using black backing. Have to clean it off the arm and the hoops all the time. thanks Bill

No Bill,
It is not common. What I have found is that the sewing arm cover (silver color) unfortunately has very clean and sharp edges from when it was cut at the factory. If this front edge is slightly higher than the back end of the needle plate, the sharp edge will cut a hole through the backing around the furthest back edge of a small round hoop while sewing.

Try loosening the four set screws on either side of the sewing arm cover and see if you can set the cover further down into the sewing arm so that the leading edge is equal to or slightly lower than the back edge of the needle plate.

If that doesn't work try this...
Remove the sewing arm cover from the machine. With a grinding file, grind down the top edge until it is tapered down - possibly a 45 degree angle. Then take fine sand paper (around 600 grit) and polish the tapered edge to smooth down any rough edges created by the grinding.
Replace the cover making sure the newly tapered edge is facing the front of the machine. Verify that the leading edge has a smooth transition from the needle plate by sliding your hand front to back across the two surfaces.

Hope this helps.

Who made the backing?

[Bill C @ Fineline]

The backing came from Maderia, it is 3oz squares Bill

Actually it can be very common. It depends on two factors. One - how you hoop and Two - how cleen you keep that arm! Clean the arm daily with a little sewing oil to remove any debris and remove friction. Don't over oil or you may see a stain on a garment. When hooping, keep the ring level with the bottom of the hoop. That should do it!

I have had the same issues with Madeira backing. Most of the time it shows when I use the Hoopmaster. Spoke with a rep that told me it may be a slight excess of adhesive in the manufacturing process. No doubt that Fred Lebow can shed some light on this as well.

I have temp. solved the problem by placing alum tape over the joint. This helped a lot. On one machine I filed the bottom edges on the arm cover down so it would go down more to be even with the needle plate. We are going to call Melco to se what they say. This is poor workmanship, the needle plate and the arm cover should meet perfect. Anyone else had this problem?

[HERB]

You may have a machine issue if your components do not fit correctly but I have used several different backing producers and the only one that gives me this issue is Madeira. It was really bad on a batch of white 2.5 oz that I got 2 years ago. Had to clean the arm after every 2-3 shirts at 3500 stitches each.

If its not an adhesive or sticky stabilizer I do not know what adhesive the rep refers to
IMO It sounds a little like BS
