bottom line is if you had a belt sander that had a rock on its surface in a conventional sander you would see the area of affect on the work surface. By adding the 10degree angle to a sanding belt, its still there, you have not address the issue of the faulty belt, you just spread it out over a wider area, so instead of a small line in the work you have a several inch wide tear out.
Hey Greg. We happily invite you to our head quarters to experience first hand the difference this sanding technology makes. At exhibitions (for example) I have personally demonstrated the difference between parallel and oblique/diagonal sanding to literally dozens of sceptical woodworkers and I have yet to meet one who is not impressed with the results. And yes, you are right: The sanding belt defect is still present and yes, it is distributed over a larger area of the work piece but the intensity of the effect the belt damage leaves on the work piece is distributed as well which makes the sanding traces on the work piece much less visible and tangible. Actually, for the human eye it vanishes almost completely, which is a great advantage, for example in lacquer sanding. We are producing these oblique units for many years now (as you can tell by the age of the video) and have thousands of convinced users world wide.
We got another straight line sander against my better judgement. Same old problem, straight line sanders leave straight line sand marks. Always have, always will. We desperately need a sander like this.
+Louis Cypher The difference is that if you just turn the piece at an angle you will sand at an angle but will still feed the piece straight through the sander, whereas if the belt itself is slanted to the conveyor, it is akin to continuously moving the piece sideways as you feed it through the sander. An imperfection line on the sanding belt will translate to a diluted, less visible area on the sanded piece. If you just turned the work piece it would still be a visible line, albeit at another orientation.
Predictive Innovation Inversion technique finds the solution nearly instantly. 1. State dilemma: Belt must spin same direction as conveyor to move wood but belt spinning same direction as conveyor causes streaks in wood. 2. Invert each unique word: Belt must spin NOT same direction... 3. List assumptions. Same direction is required to move wood 4. List generalizations: Direction must be completely the same direction 5. List opportunities: Partially same direction
+Ricardo Brisolar no matter what angle the belt is at, there is still a problem with the belt, which has not been addressed, just made it cover more surface area so you don't see it as well, its still there, so no, not a great idea.
Ricardo Brisolar in correct, gouging of the wood by a belt cannot be corrected by having another piece of the belt pass over it. Changing the angle just makes the gouge that much larger
As explained above in even greater detail: Yes, the sanding belt defect is still present and yes, it is distributed over a larger area of the work piece but the intensity of the effect the belt damage leaves on the work piece is distributed as well which makes the sanding traces on the work piece much less visible and tangible. Actually, for the human eye it vanishes almost completely, which is a great advantage, for example in lacquer sanding. We have proven this literally thousands of times. :-)
Old Machine. "Ok, Pedro, you lightly sand out imperfections from old machine. I pay you $2 an hour to do this." New Machine. "Ok, people, you all are fired! New machine cost $100,000.00, and has no imperfections."
Kundig Duplex... I believe it's a step forward in the sanding world, but... The advertising company didn't even bother read the name of the machine correct. The voice incinst it to be Kundig "Ouplix".

+1 like for the hilarious worker/actor in the beginning.
to Alex Fibro, he's clearly saying OBLIQUE sander which is fairly logical considering the way this machine works.
This is like watching UAC videos in Doom 3.
How convenient the machine in the introduction knows there is a defect comming and stops its delivering so the man has enough time to inspect it

Sanding pleasure? Who is this guy? :)
Those guys patented sanding at an angle? He even says "Its clear that starting with oblique attack angles woodworking is easier!"
what's the difference between turning the work piece to an angle vs the sander itself? seems to me it'd be the same thing.

A simple idea that nobody has even thought of... applauses.
Doesn't work that well.
great idea...

+Greg Ward actually is, because if a line of the sanding is damaged, another part of the sander will pass over, and so not marking the piece

how many fingers get caught in the wide gap of that first machine?
Too many I guess !
+Fleur Black no more or less then a conventional sander, that is the same on all types, your statement is pointless
If your dumb enough to stick your fingers in there, go for it.
how the fuck did I get here from diablo 3 videos....
So the whole thing is just rotated a small bit? ...Genius.
Doesn't seem as impressive. but then again. The simplest solutions usually are. :)
@Assimilate71 the Germans and japanese are the best engineers in the world.
So wait, are these oblique or no?
It's Super Mario!!!
They use TRIZ
Cool machine, dumb tagline... sanding a pleasure??? Maybe if the thing can make me a good sandwich, that might be pleasurable.
Shut up and take my money!
How racist, first the wood with deffects is white, but the smooth one is black.
Sanding pleasure? Who is this guy? :)
