Adler 69 Reverse Stitch

[Gregg From Keystone Sewing]

Both machines are really good.

I've had no problem at all with the reverse. I also have been wondering why the plate was limiting the reverse stitch... (when calibrating machine I've noticed that I set forward stitch to equal the maximum reverse... this made me look closer to the plate) Mine Adler is 69-372. I didn't have time to investigate it properly, but it seems that 69-372 has 4mm stitch and 69-373 has 5mm stitch, if anyone knows some facts please let me know.

It would be strange if only the plate would differ those two models, but who knows...

Here is an update about reverse stitch adjustment. Some of You know the video from youtube on this operation. But I've noticed that You don't have to disassemble all elements to make the adjustment. I don't know how to name some elements in English, so there is a photo below.

1. Remove the "A" element

2. Loose the lever "D"

3. Unscrew the knob "C" (not totally),

4. Put the reverse stitch lever in maximum reverse position, screw in the knob "C" until inside the machine it will touch the "mechanism" (when machine is set to max. reverse or max forward, the "mechanism" rests on the stitch length screw/knob),

5. Tighten the lever "D".

6. Now You check how forward and reverse stitch matches... It does not match, so... In my machine when I tighten the lever "D" it clamped/binded three parts: Knob "C" + Lever "D" + the hidden screw which adjusts forward/reverse stitch, lets name it "X". Now You do it.

7. Loose the screw "B" and now You can adjust the "X" element. This element looks like the screw with an off center hole. If hole goes up reverse goes longer, if hole goes down, forward goes longer. So You turn the Knob "C" now (with lever "D" and "X" element together) to adjust reverse. Every time You make a change You have to tighten the "B" screw, check point 4. again , check if stitches matches, if they don't unscrew "B" and adjust and screw back "B".

8.When everything is set, tighten "B" and put "A" back again. Done.

I know it all would take 5 seconds to show in a video, but I've tried to make it as clear as possible. If the "X" is screw into the iron cast so deep, that the lever "D" is not resting on it, You can screw it out a bit. I've noticed that it does not affect anything if "X" is deeper in cast or not.

Hello Adler 69 owners.   I have joined your club and also experience reverse stitch problems.  I know this is an old thread but does anyone have any more information?  Did removing the cover plate result in any issues?  Did anyone fix this issue?

It says on my machine : Adler 69 - 72    (is this a 372?)      /E 42   435270

With the reverse cover plate removed, i get around 6mm forward 5mm back.  With cover plate in place, i get 5.5mm forward 3mm back.  Before I take the plate to the grinder how are you guys getting on with it?

No   I believe the 69-72 does not have 4 motion drop feed like the 69-372, 373.  It was used for binding.  The difference between the 69-372 and  69-373 was that the 69-372 was made for smaller threads and needles.    Normally the hole is smaller in the feed dog and the balance wheel on the two machines may or may not be different diameters.  Same with model 69-72 and  69-73.   Smaller hole in the feed dog.  Adler also might have changed a part or two inside the machine to accommodate heavier thread and sew thicker materials.  They had a lot of sub classes.

Very interesting Glenn,  any more information on the 69-72?  I'm having a lot of fun playing around with it as its my first industrial machine.

 

Reverse spacing is now sorted, however the reverse leaver cover is staying off as it limits reverse stitch length, as other above have found.

I believe the 69-72 takes needle system# 135.  Sizes up to #120     The 69-73 takes up to #14-160 I believe.  Good machine.  Just take the feed dog out and enlarge the hole with a Dremel and carbide tool or Mitchell Cord.     These are good machines. If you can go on the sew24bogspot.com, it may have the original brochure on the machine that explains the sub classes.  I have it but have to find it.

I found the correct site that has the brochure and explains the different sub-classes.  It is :  Sew24.blogspot.de.     Click on downloads window.  Go to the list of brochures at the bottom of the this list and find model #69.  click on it.  Brochures come up.  Go down to about page 6 and there is the brochure for your machine.  the maximum needle size is#110.  Yours is or was a binder machine.  E42 signifies the type of feet on the machine and how wide the range of binding tape it could handle.  Hope that helps.  Also, the maximum stitch length is 4.5MM, not 5mm or 6mm.
