Auto Bottom w/ Glued Hanger - Bobst Folder Gluer

Auto bottom with glued hanger. These can be difficult to fold if entering the default measurements for the combifold in the CUBE.
In this situation, I added 20mm to the flap length, which results in the backfold shaft raising an extra 2 increments. Then I added the ‘clips’ to the hooks. As you can see in the video, the hooks tips are actually missing the back of the carton by several millimeters on purpose and I’m using the clips to do the folding. That, in combination with the extra shaft height creates a better, longer folding arc to fold the flaps.
Typically, on this type of carton, if you enter the correct dimensions in the CUBE and try and fold the flaps regularly, the flap won’t fold on the crease and will create its own crease way ahead of the crease and just fail to fold correctly.
Using this method will keep from having to prebreak the back flap on all the cartons, which can be a chore if the run quantities are high.
Also, notice how the back fold hooks actually reverse after they fold the flap and stop. Until I used slow motion to record, I never realized that the hook shaft reversed after the fold. Interesting…

Question: how do/would you fold the glued hanger (we call it a eurolock, why i dont know they just call it that way) if it is on the front of the box, lets say its a box with a Z fold interieur and normal bottom and top.
And the hanger is really small like 3x2 cm (1.18x0.70 inch) with the hole being almost the same size of the panel.

Yeah. We have a carton that we run kind of like what you’re talking about. I would pocket fold the euro lock. That way the pocket folder forces it to fold on the crease. You’ll need a rail underneath the carton so that when the flap hits the pocket fold, there’s good support underneath. I never had any luck doing those with folding hooks. It’s hard to get the flap to fold on the crease, especially with the hole there. It usually wants to fold off the crease and in the middle of the hole instead.
If you do try using a folding hook, you’ll want a hook length that is extremely short. Perhaps 1-2 mm. Just enough to grab the flap. Then use something as a ‘stop’ behind the hook so that the hook is restricted and only allowed to travel a certain amount. When the hook hits the stop, it will cause the flap to fold at the crease. It’s almost like making a pocket folder out of a folding hook and a bar. Like I say though, I’ve never had too much luck with consistency with this method. I much prefer the pocket fold method instead. It’s a lot more positive.
I’ll try and get a video for you when we run it next. It might be a couple months, as we don’t run that one a lot.
Watch this video that I made a while ago:

I know it’s not exactly what you’re talking about and the euro lock is a lot bigger here, but it’s the same concept. You’ll just be doing it on a much smaller scale. You can make a small little pocket folder with some scrap plexiglass and metal.

@@masterfolder3155 And what if you dont have a pocket fold... i made something myself from srap but it is more like a upside down V shape thing with air coming from under and a bar on top of the carton to get some short of timing on the crease... i runs fine but sometimes misses or folds one the hole....
