pcox Report post Posted December 13, 2012 seems like you do not have tension on the upper thread. Quote Share this post Link to post Share on other sites
trekster Report post Posted December 13, 2012 Be sure the thread is unwinding from the bobbin in the proper direction, and that your bobbin tension is set relatively in a neutral setting. If those things are okay, may want to check the needle is seated correctly and the scarf is in the proper direction. Last thing to check would be the timing, to be sure the shuttle hook is always picking up the thread. Quote Share this post Link to post Share on other sites
Wizcrafts Report post Posted December 13, 2012 Top thread bunching up on the underneath is almost always caused by one of these things: No tension, or too loose beehive spring tension in top thread disks Excessive spring tension on bobbin thread Bobbin thread jammed against bobbin case or shuttle race Failure to hold back the threads, or at least the top thread, as you start to sew.

Sylvia Report post Posted December 13, 2012 (edited) Did you get an instruction booklet with your 99k? If not this PDF will help you at LEAST get the thing threaded correctly.

educatedcobbler Report post Posted December 13, 2012 this sewing fault can happen due to ---- incorrect sewing tension (adjust the tension) ----needle incorrectly set in needle clamp ( reset the needle) ----incorrect threading ( re thread machine ) ----poorly lubricated thread ( use better quality thread ) ----feed dog sway ( tighten the feed dog ) ---- pressure foot bounce ( proper pressure foot ) Quote Share this post Link to post Share on other sites
Anne Bonnys Locker Report post Posted December 16, 2012 Clean it. Crap in the bottom end or tension plates will cause all sorts of nastiness. Occasionally the whole tension assembly is too far in which causes the tension to be released when you try to sew anything thicker than two layers of silk. Test this by slowly raising the presser foot and working out where the tension plates start to release. Quote Share this post Link to post Share on other sites
Sherkhan1962 Report post Posted February 4, 2013 Thanks Sylvia for the booklet links - really free PDF are often hard to find. I just bought a 185K, cosmetically refurbished model of the 99K, but the mechanism is the same. Hand shake or kiss, you chose - because I noted you won't tell your gender Quote Share this post Link to post Share on other sites
