Attack Angle (Degree)
Figure 1 Attack Angle
The user can measure an attack angle when a head or a tail of sheet is contacted with a linear guide, arc guide, fixed roller, or movable roller as shown in Figure 1. (In the case of fixed and movable roller are similar the arc guide case in Figure 1.) If two sheet-heads or two sheet-tails are contacted with a guide, the attack angle of later contacted sheet will be reported. The value of attack angle is always reported in the degree unit and less than 90 degree. The value of attack angle can be calculated from the following equation.
In the FE fixed roller or FE movable roller case, Attack angle is defined as Figure 2. If the deformation is small of the FE roller, then the computing result is similar to the attack angle of the rigid roller.
