Adler 267-373 Problem

[chiocciola]

Hi all, i'm a new member of the forum. my name is Alessandro and i write from Milan, Italy. actually i don't sew leather but i'm working with fabrics for military equipment so the machines are similar... i recently bought an used adler 267 373 and when i was playing with it for the first time i got some thread stukked in the bobbin area. i found this cool video

)

with the explanation for unmount this part, i did it but now the machine it is not working, is like if the down thread is not catched by anything. i saw there is a long hole near the bobbin area for some regulation but actually i don't know exactly how to use it... i came from an old singer 331k24 and the system is really different and i feel a bit lost. I hope to find some help from you expert guys, thanks in advance to all.

In the first picture, there is a little tab on the bobbin basket that should be trapped in a slot under the needle plate. It the basket is not kept in the right position, it won't sew properly, sounds awful, and breaks the top thread. The tab is in the 7:30 position, should be in the 9:00 o'clock position. This is similar to my machine even though different make/style.

Thanks Tom for the quick reply. i did the change you mean, i didn't see at the start but i think now it is in the right way.

i tried again but it didn't sew, probably i have also to regulate the screw on the right but i don't know in which way i have to put it.

thanks

it´s probably - as most of the times - the needle / hook timing that is wrong.

Do you have a manual where the procedure is mentioned?

[chiocciola]

thanks for the reply.

actually i have the manual but the part about the timing is not explained... here there is the list of manuals avalaible for this machine https://www.duerkopp-adler.com/en/main/Support/downloads/index.html?action=search&prop0=%2Fcommons%2Fdownload%2Fpublic%2F267%2F&prop1=%C2'> do you have any good video tutorial of a similar machine for learn how to timing the hook-needle?

thanks

thanks for the reply, unfortunatly i already had this book and it didn't helped me.

i did a video

i'm reading manuals about fixing timing but most of the photos are for vertical bobbins.

ps. i'm using 134-35R needles #21

thanks

The hook is retarded by at least 1/4 turn. You may need to find out how to advance the hook. But, first you should set the needlebar to the correct factory setting, to make sure it is not adjusted too high. This could happen if the needlebar screw got shaken loose by the pounding of sewing hard leather. It could have slid up a smidgin at a time until it went completely out of reach of the hook.

Ensure that you are using the specified needle system.

thanks for your reply. today i'm going to take a look to the needle bar. about the timing do you have a nice tutorial o explanation for understand which parts i have to regulate? i understand a bit how it should work but honestly i don't know which part i have to regulate for first.

thanks

I don´t have an Adler 267 but these triple feed machines have basically the same mechanism.

I took a shot out of a 267 manual so here is a picture (see below)

Remove the needle plate and turn the hand wheel until the tip of the hook meets the middle of the needle. Now you hou have to loosen the two screws at the clamps of the needle bar frame and you have to lower your needle bar just a little bit. Just as much until the tip of the hook meets the needle within the scarf just 1.6mm above the eye of the needles during the upward movement of the needle bar. Now fasten both screws tightly + evenly. Do some test stitches by turning the hand wheel and see if this works.

The hooks turns twice and it meets the needle scarf when it finishes the 2nd turn.

Maybe you have to "play a little bit" but this is how it works on the majority of triple feed mechanism of this class and I´m sure it will be the same at the Adler 267.

Sorry no Video.
