Pfaff 335 Manual For Older Version Needed

[Uwe]

It's quite possible that your binder is set up perfectly fine and it's your tape that's not the right size for the folder. It needs to be pretty much EXACTLY 26mm wide for this folder. You cannot use a 26mm folder with 20mm tape, for example.

They make folders in very small increments to fit a specific tape size:

It looks like a huge folder attachment - are you sure it's intended for a Pfaff 335?

If the tape size is right and the folder is right, perhaps it is supposed to be further to the left, lining up with the inside edge of the outer presser foot and stay in front of the feed dog:

Maybe Joe from HockeyMender can chime in - he's the resident expert of Pfaff 335 binding operations. I'm just making slightly educated guesses.

Hi John, i have put the binder setup on and taken a few pictures. it looks like the same setup as i have basically apart from the binding tape. i have used some thin leather cut to 20mm wide as marked on the binder attachment. this feed dog is generic and the needle is right up against the right hand side and i don´t have any more room either to move it. so it would have to be filed or sanded down to line up the needle in the hole, but if that is the case it would shorten even more the distance from the edge of the binding material to the needle entry point as it would push the binder attachment further to the right?? maybe they just made the needle hole too much over on the left side??. i broke 2 needles size 120 in the process then changed to a 110. this is just slightly thinner and has not broken. like uwe said, the needle bar has to stay where it is otherwise you will hit your hook on the bottom or you will have skipped stitches or none at all?? looking at your pictures john i can´t see why you are not stitching on the bias binder tape? check out a thin piece of leather and try that?have a look, regards jimi.

Hey all, first off I wanted to say a big thanks to everyone who's been helping me troubleshoot this issue. This forum is a huge help and very useful. Now down to business.

I reinstalled the bottom feed dogs and reassured that all of the parts were properly tightened and in place. I think the bottom feed dog was loose and cause the tape to move around underneath the material resulting in the dropped stitches.

That being said I think the feed dog may not be properly machined and that the hole is not completely in the correct position. I will try a new feed dog set potentially in the future.

I will also try a 24mm binder. I'm using 1" tape so I thought the 26mm would be appropriate. I do also have 7/8 tape so it won't go to waste.

I may also try to machine away a bit more of the feed dog to allow the binder more room to adjust to the left.

I will post my results when I get back to the shop.

Thanks again everyone!

Joe (Hockeymender) kindly lent me his copied vintage Pfaff 335 Instruction Book and a set of mechanic's service training instructions pages. I've scanned them into PDFs in the best quality the originals would allow, which is overall quite nice. I also ran text recognition (OCR) on the files, so the PDFs should be text searchable.

You can download the Pfaff 335 Instruction Book here:

Pfaff 335 Instruction Book (old casting, until the late '90s)

The service instructions cover various older Pfaff models:

I'll also try to upload the instruction book to manualslib.com to make it accessible to a larger audience.

Great thanks Uwe! God bless you men! Big respect!

You may be out of luck finding a manual for the old Pfaff 335 online other than some subclass parts lists.

Your best bet may be to start with a manual for the Pfaff 145 (or the Pfaff 145 Parts Manual). The 145 was essentially the flatbed versions of the old 335. Everything above the bed should be the same, including threading diagram, stitch length regulator, needle system info, etc.

For what's going on inside the cylinder arm, look at the manuals for the new Pfaff 335 version (see manual links at bottom of the linked page) and hope that very little has changed in the cylinder arm area.

As for dating a Pfaff machine, I came across this attached chart some time ago:

Figuring out how to post a picture in this forum may be harder than getting your Pfaff 335 to work properly.

Thanks for this lists...  The engineer's manual will come in very useful for my "new" old machine.  Thanks for the effort you put in to the community.

Uwe, 

Would these Pfaff 335 manuals be similar to a Pfaff 337-734 as I just purchased a 337-734 from Techsew and looking for manuals while waiting for it to come?

Thanks,

Billy
