Binding Machines Buying Guide

Question by RoB: Why when you sew on thick material with a zig-zag machine does the thread tend to flag on the right side?
I am a sewing machine mechanic and I run into all kinds of problems but these ZZ machines are tough to figure out ! First of all, our ZZ’s are set up with core edge folders and and we run material anywhere from 1/64 to 3/16 thick. Now combined with the binding thats pretty thick! The thicker the material the more the thread flags and skips on the right side. I know that putting pressure on the foot and rising the needle bar along with timing the hook as close to the eye of the needle as possible helps, but there has got to be a better way. I am looking for any ideas I could try.

Try a thicker needle and loosen the tensions . Some times the needle is too small and bends slightly to miss picking up the bottom thread . You may have a ballpoint need;e in there from doing wool or nits . They are not sharp enough for thick material .

Thread or needle lubricant, or lower elasticity of the thread might help, too.
