Lakil7 Report post Posted January 5, 2022 Hello, I hope everyone is safe and well. I am a new member to this forum, but have read a lot of wonderful advice from members. I have an adler 30-1 shoe patcher machine and am having some problems with my top thread getting caught up and balled up in the bobbin case. and shuttle. It seems to be happening more frequent. When this happens, everything gets jammed and the machine would snot titch anymore. I have to get under the work and cut the balled up thread, take out the bobbin and case and clean the thread out of the shuttle. Can anyone tell me what might be causing this issue. Thanking you in advance. Quote Share this post Link to post Share on other sites

Wizcrafts Report post Posted January 6, 2022 Have you tried adjusting the slack adjuster and the take-up spring on top? The adjuster ranges from no effect at the top to lots of slack thread at the bottom of its adjustment range. If you set it at the top position, only the spring on top comes into play. If that spring is spread out, or weak, it can't maintain tension on the top thread as the machine cycles through the take-up motion. That could cause the screw-ups in the shuttle. Another part that affects the quality of the thread loop at pick-off time is the paddle shaped spring in the needle bar. If that little spring is twisted/bent, or broken, stitch quality will be inconsistent and hard to maintain. If you need patcher parts, contact Toledo Industrial Sewing Machines (an advertiser here via top of page banner ads), or our member, @shoepatcher.

Lakil7 Report post Posted January 6, 2022 Thank you guys so much for your response and suggestions. Wizcrafts, are you talking about the adjuster that has dunn, mittle and dick etched into it. Is that the slack adjuster? BTW, i am using a #140/22 needle and #69 thread top and bottom and I am using the smaller hole on the needle plate. I did read that you recommend using #18 or 19 needle for #69 thread, and i have ordered some of those needles. Quote Share this post Link to post Share on other sites
shoepatcher Report post Posted January 6, 2022 No, he means the paddle shaped spring screwed to the needle bar just above the needle clamp. glenn Quote Share this post Link to post Share on other sites

Is that the slack adjuster? Yes, that part adds or subtracts slack thread during the take-up cycle. When you move it down from the top (Dunn), the adjuster forces the check/take-up lever to stay above the bottom position, pulling more thread from the spool. Set it for the best results in thin, thicker, or maximum thickness projects. One thing the adjuster does when in action is to let you get a longer stitch in thick material. It accomplishes this by taking some back pressure off the needle and foot because of the extra slack thread. If the adjuster is all the way up, the thread tension pulls hard against each stitch. This doesn't matter much in 8 to 10 ounces but sure does matter at 1/4 to 5/16 inch. You are already losing maximum stitch length due to the pendulum effect. Adding some slack thread will return a little bit of length. Quote Share this post Link to post Share on other sites
Lakil7 Report post Posted January 8, 2022 Thank you so much Wizcrafts for taking the time to respond, and your insight. The little small screw that keeps the slack adjuster tightly in place was very loose so i guess it was causing the adjuster to be inconsistent. I tightened the screw, set the adjuster to dunn, sewed a few projects and have not experienced the problem. Very happy about that. Thank you for your wisdom.
