Binding with a right angle binder on a walking foot machine

[Dave9111]

I am using a Pfaff 1245 walking foot and I purchased a right angle binder setup probably 10 years ago and I have never been able to master this thing.

I bought 100 yards of polyester single fold binding from Rochford supply years ago and it works ok on straight runs or large curves.   

The Rochford binding is rather stiff so I have to fight it when doing tighter turns, about 6 inch radius and less.   So I thought I would try and buy some double fold polyester binding off Amazon, it was cheap.  Its a thin material but it doesn't work well in the binder.   Somehow it rolls sometimes after making the turn in the binder.  My guess is that it is not stiff enough.

So what next? 

Rochford, Wawak, and Amazon all have a lot of binding, but I have no idea what will work well in this binder.

Do I just keep guessing and buy a few different kinds?   Wawak offers heavy, medium and light single fold binding.    Is there any standard for what is Heavy, medium and light?

Would woven, unfolded, twill binding possibly work?  

I never thought that binding would be this challenging!   Are there any how-to's written on how do run a binder?  

Are straight binders more forgiving than right angle binders?

Thanks,  Dave

@Dave9111;

Many years aago I had a sew ing gig that required me to sew binding onto the edges of road workers' safety vgave ding run off the top or bottom on turns, especially inside turns. The vests had outside and inside curves. I  tried inexpensive oriental binders, but they let the bindinsg run off the top or bottom on inside curves. My dealer recommended getting a custom binder made by a specialist. It cost the boss $400 for that binder, but it worked flawlessly. If you aren't getting satisfactory results with a stock binder, look into a custom made binder that's made to work with a particular binding material.

The right angle binder I had made double-folded binding out of flat 1.25 inch polyester edge tape.

I use inline/straight binders single fold and double fold from 1/4" to 3 1/2" on all my machines whether they are flatbed or cylinder arm. The main advantage of a 90 degree binder is that it should be able to do tighter corners then a inline/ straight. The disadvantages of the 90 degree binders are i) they cost a lot more then your inline/ straight. ii) you can't on most adjust the tension on the tape at binder itself. The main problem I think you are having is poor back tension on your tape and the path the binding tape travels through the binder is to wide so you are getting tape slop. 

Are you using your binding tape with a vertical or horizontal platter or just letting it drape to the floor??

Any photo's of your binding setup???
