Rollers - Horizontal Tilt Adjustment

[MobileSawMilSlo]

Hi

When looking into the Wodmizer manual there is the topic of "Horizontal Tilt Adjustment".
Both rollers should be tilted slightly to the left (A = B - 6.0 mm [0.24"])



 

I am wondering why is the reason for this? Why the rollers left to right should not be the same?
What would happen if they would be the same on both sides?

Just wanted to understand the basics .

Thx

When the blade is pushed back against the flange it contacts the right side which is traveling upward and thus draws the blade into tighter contact with the roller.  

If it was tilted the other way the left side would contact the blade and cause the blade to push away from the roller and loose solid contact with the roller.

You are right of course.

So in the ideal world, it could be also parallel on both sides, but in the real world, you would never know which side of the roller would blade 1st touch ... probably the left one correct?  

Thank you for your explanation.

If the blade contacted the flanges in any other way than designed it would surely chatter.

I've set my guides late one night in the complete opposite direction to that, short on sleep, looking at the ruler angle and just not thinking about it properly. The band does exactly what you'd expect it to, when the pressure comes on, it contacts the flange, the flange carries it out to the edge and it slips off that flange up and over it. Obviously changes the cutting axis in the process and causes wild waves... Do not recommend =).
