Members tnawrot2 Posted September 4, 2013 Members Report Posted September 4, 2013 The picture shows a single layer of thin leather, try doubling or the leather to get at least 12 0z or more. Being it is new to you, do you have it threaded properly? Knots on top means loosen top tension. Quote
Members ec2121 Posted September 4, 2013 Author Members Report Posted September 4, 2013 i followed Weavers guide to threading a adler 205. i increased the tension and i even tried two and three layers and still the same. the tension seems ok but then i tried it with alot more but still no diffference. all i know is that i'm going through alot of thread trying to trouble shoot this....haha...

As mentioned above, reduce the top tension. It is too tight and pulling the knot right through. If the tension disks are loose, remove a wrap from around a guide post too. Make sure the thread is pulling off the spool and not getting hung up. Tom Quote
Moderator Wizcrafts Posted September 5, 2013 Moderator Report Posted September 5, 2013 If none of the above work, check the bobbin thread to make sure it is feeding under the tension spring on the bobbin case. Tighten the bobbin tension if necessary to lower the knots..

Members ec2121 Posted September 5, 2013 Author Members Report Posted September 5, 2013 the thread is pulling freely from the spool with out any tension until practically it arrives at the disk tensioner. i think i have the tension ok...not to hard to pull. now that you mention it Wiz, i'm not sure if the bobbin right?? i have it feeding through the middle of the case...is that wrong? do you mean the hole at the very bottem of the bobbin case??? and if needed how do i tighten the tension on the bobbin??

Moderator Wizcrafts Posted September 5, 2013 Moderator Report Posted September 5, 2013 Sorry, but I'm not familiar with that model. But, every bobbin case should have a smallish, mostly flat spring at the end of a slot, where the thread feeds through on its way out of the case. You must feed the bobbin thread under that spring to have any tension on the bobbin thread. If you haven't done this, or, if the spring is missing, you won't be able to control the position of the knots.

Moderator Wizcrafts Posted September 5, 2013 Moderator Report Posted September 5, 2013 Okay, I found some details about the machine. It is a clone of an Adler 205. The bobbin case is much like the one in my Cowboy CB4500. It opens on a hinge pin to insert or expel the bobbin. There should be a long slot on a diagonal, running from the edge of the case to a leaf-like spring. One end of the spring is simply screwed down to the end of the case. The other end has an adjustment screw going through an elongated hole in that end of the spring. On my machine, a set screw locks down the adjuster screw. You may need to use a flashlight to locate a locking screw, loosen it, then tighten the action of the main bobbin case tension spring. It should have a moderate amount of tension, requiring a smooth, but steady pressure to pull the thread out of the case. Most of us insert the bobbin against the direction of the slot, so the thread has to make a sharp turn into the slot. This is done to appease the Hobbits.

Members ec2121 Posted September 5, 2013 Author Members Report Posted September 5, 2013 ok, i'm not sure if i understand you correctly but there's two scews inside the bobbin one smaller than the other. the larger one goes all the through the shaft thats in the middle of the bobbin...is that the screw your reffering to.???

Members ec2121 Posted September 5, 2013 Author Members Report Posted September 5, 2013 also the spring seems flimsy to me but is that how it's suppose to be...? Quote
