Members bobkiss Posted January 31, 2014 Members Report Posted January 31, 2014 Hi guys, I hope someone can help me. I have a Nakajima 280L, it keeps fraying and breaking the top thread!! What I think I know is this, if I sew very slowly I have no problems, if I speed up it breaks, if I go in reverse it breaks. The issue happens as the needle disappears through the throat plate. I have checked everything for a rough spot or a burr, all smooth. I reset the timing and the problem got worse. Any suggestions would be appreciated.... Bob Quote
Members Narvi Posted February 1, 2014 Members Report Posted February 1, 2014 When I had a similar problem it turned out the needle was inserted backwards (concave part should face to the right.) Just a thought. Quote
Members bobkiss Posted February 3, 2014 Author Members Report Posted February 3, 2014 Thanks for the suggestion, I checked and the needle was in correctly. The problem seems to be related to thread tension. If I lossen the bibbin thread and tighten up the top thread it seems to sew better. Makes no sense to me.... Quote
Members dpalmer0831 Posted May 19, 2014 Members Report Posted May 19, 2014 Any luck with this? I have the same machine with the same problem. Quote
