Problems with elna 7000


Hello out there I am sitting and looking at my woman's fine mechanics - a Elna 7000 - after a little congestion is it not catching the thread any more from the bobbin cabin - now I have sat and looked at the thread holding things and grips and may well understand that it does not work more - either missing some "catcher" or the present is bent completely out of position see

Have you tried using a new needle?

Have you CLEANED the Bobbin and the place that contains it ? Sometimes a piece of thread Caught in the `bobbin House` , does that ?? also look carefully if the PLATE sits well on it place !!! mirjam

hi mirjam / irene and other If you have a few minutes spare then try to take a quick look on the pictures of it - if you have a Elna yourself - and let me know if that mechanishm which rotates around the bobbin house and will catch the thread - either is something missing there (besides of the house I have removed) or it is bent - couldn't you try to describe to me if there is some knob or other sort of catcher there? /ti

I have two vinage Elnas, same type of bobbin area, and don't see anything missing or bent.

hi again hmmm
looks fine to me - the surronding pinion of the bobbin case rotates fine but I had expected some sort of "catching mechanism" to catch the thread from the bobbin?

I'm *not* an expert, Ron is, but you might find something here which will help you diagnose the problem:

The hook to needle timing is as follows When the needle has risen 2mm above bottom dead center the point of the hook must be central to the needle and just above the eye.

The 'catching mechanism' is called the 'hook,' and it's right where it's supposed to be. The timing might be off, but the hook is there.
My vintage Elna's do NOT like any stray thread caught in the hook/bobbin area, so make sure that area is completely cleaned out.

check the hook
rotates fine but
thread from
yes, as others have said the catching mechanism is called a hook. the hook is just a sharp pointed piece of metal. the hook is suppose to pass less than a a threads width away from the needle to catch the thread.
When you manually operate the machine does the needle descend into the bobbin area ? Does a sharp pointy thing pass by the needle very close while the needle is moving up from dead bottom ?
If the hook is not almost brushing the needle then that could be source of trouble.

hi again
yes - no problems
yes it does - you might be able to spot it on the pictures i send a url to on my very first post
it does - ver y close - i would say about ½ - 1mm
but - this hook should catch the lower thread would I expect which it should throw around the needle in some way - but it doesn't catch the lower thread from the bobbin ? I am a bit in doubt here..

hi again
I don't think the timing is wrong - the hook passes the needle just as they pass each other - and there is no wear there at all
Well - I have removed a lot of "dust", 4 broken needles etc etc :-) - but if I could figure out how the hook catches the lower thread - or should do - I think I culd fix the error...

It doesn't catch the lower (bobbin) thread, it catches the UPPER (needle) thread and pulls it around the bobbin case to form a stitch. Take a look at the link I posted:

down about 2/3 of that page, you'll see an animated graphic of exactly how each stitch is formed.Beverly

The hook doesn't catch the LOWER thread. It catches the upper/needle thread.
If I were this guy's "woman" he wouldn't get within 50 feet of any of my "fine mechanics". And I do understand English is probably not his first language, but he could actually look at the provided links. Furrfu...

hi again ok - now can I see how it works - I expected that the hook should catch the thread from the bobbin but it catches from the needle - takes a tour around the bobbin and in this way catch the lower thread...
hmm - the timing is completely gone - when the needle is at bottom dead center the hook has gone 90 degrees around already but the problem also started in some real heavy cotton - is it the arm which controles the needle I have to adjust or is it the gear which drives the hook?

Hi Bev - thanks for the tip - I have just been figured out how it should work - I expected it was the other way around but now I can see the problem - the timing - according to the tip Ron gave has gone - more than 90 degrees wrong... Well - I expected that I could have adjust the arm activating the needle but this isn't so on this elna - I think I have to adjust the hook to fit with the needle - and this will probably take some hours in "try and error" - so - I think I'll stop for today and see further thursday.

hi out there - somewhere
hmmm - is this the common language and net-ethic in the net in this area? - but if you start with a problem described in danish (thats the common and natural language in a small country named Denmark in the northern europa) - translate it with googles machine translator - take a quick look and press "send" it is easy to miss a lot of spelling errors and wrong terms - which might offend some - but I normally express myself - or at least I try - in a way so that I don't need to be emberassed to sign my contributions with my name. But I am glad and happy for all tips, tricks and help I get when I have a problem which I try to get some help with on the net...
best regards /Thomas Iwang

I did acknowledge that you were probably not an English speaker, and that might contribute to your referring to your "wife"(?) as your "woman" in your original message. Pardon me for taking offense, that's not a common usage here.
I checked your headers and determined that you were posting from .dk, and I made some mental allowances for that. But I posted a message several messages up in this thread pointing you to a link which shows how the hook works, and yet you persisted in writing about the hook catching the bottom (bobbin) thread. I assumed you were either ignoring the information on that site or didn't understand it. My apologies for the snarky comment on your language skills, your English is 100% better than my Danish.
I also sign my real name:

well - in the same second as I used "send" I could see that this &#%& machine translator had replaced the danish term for wife with "woman" and I also got a glimse of some cave-dwellors in my head - but - when you have pressed "send" it is out there and there is no way to get it back...
