Do you mean every 6 or so the stitch thread is actually "cut". Is it top or bottom thread? I cannot imagine, if the thread actually breaks in two pieces, how you are able to continue sewing.......if when sewing, bobbin thread breaks and I continue to go I just get that long top thread line.......if it's top thread...just holes in fabric and thread waving in the breeze along side the needle or sucked up into head.....even on my L/A. Now skipped stitches....that's different.
