Welger Baler Knotter

This shows there is no stripper arm, the retainer rotates only to cut the string, and catch the next piece, the pressure from the next bale strips the knot from the bill hook.
So the string would need to slide into a knotter plate to guide it off the bill hook. Or is the stripper arm not working?

For all those that have posted about the stripper arm being bent etc it ought to be pointed out that the Welger knotter doesn’t have a stripper arm. Once knotted the bale pulls the knot off the bill hook. My money would be on the knotters not being set correctly to the string or some kind of damage to the needle carrier so that the needles aren’t quite operating in the correct position.

A point missed by a few posters is that the problem is happening on both sides. So not damage/adjustment to one side.

Why did the OP stop baling? Run out of twine?

I'd check twine threading and tension again. Very easy to put twine on the wrong side of the rollers in the needles, for example. I actually found the next video to the one above quite instructive. It seems to be in Croatian or some other language but it does spend a lot of time explaining threading. (No linguistic skills required).

Good point. Many years ago one of my neighbours had trouble with his baler dropping bales and rang me to see if I could fix it. I really didn’t have the time as I had lots of hay to bale of my own but as I was passing where it was I said I’d stop and look at it but if I couldn’t work it out in a few minutes he would have to be on his own. He’d threaded the string through the needle on the wrong side of the roller and that had caused all his problems.

Hi All & ‘greenmachine2’

Did this get resolved? My AP45 is doing exactly the same....

I put a round bale through it on Tuesday and it was perfect..... got it into the field today and it is missing almost every knot - suddenly it won’t pull the knots off the bilhook despite being tied properly.

spent 4 hours adjusting and checking everything and it made no difference at all. Knotters were stripped and rebuilt over winter so all free, clean and lubricated....

Please help me understand this!!
cheers Jon.

Oh and by the way, if you empty the chamber, pull the string back and trip it it makes a perfect knot.

bizarre..., J.

So everything remains the same except twine tension (which you've applied by hand)? Pull the string using a spring balance? If everything else is equal, it must be the factor that varies that causes the fault. Or is my logic flawed? My brain isn't very good with baler knotters!

Can I first say I've never worked on Welger knotters.
Right, I have worked on IH & Claas knotters over many years & if I can give one tip here I will.
If you've looked very carefully & cannot see anything obvious, it's time to go back to basics, that is empty the chamber & go back to the original factory settings.
Go through everything, set up the ram, set up the needles to the knotters, needle brake, string tension & the routing of the string.
Check the hay retainers & any wedges in the chamber.
Clean out the knotters & reset them by the book.
Also worth a look at the plate below the knotters, it was called the base plate on the IH.
As I said I don't know the Welger set up but this could be a problem on the IH, not on the Claas.
This plate would bow up in time & allow material over the top of the ram, when the needles came in sometimes the string would get held up away from the discs & it would drop a knot.
This could also happen if the wood block on top of ram broke off.
But to be fair they invariably tied after you went through this process & sometimes you'd not actually found a fault, it was just everything was a little bit out.

We're having problems with our AP730 knotters throwing loose bales and I think its down to baler twine quality.
What make of baler twine are people using?
