A1: Constant developed length method
While the developed length is constant, either the angle is pre-set and the radius is calculated or the radius is pre-set and the angle is calculated. | |
|
A2: Constant radius method with compensation of the previous segment
While the radius is constant, the angle is pre-set and a new length is calculated. In order to keep constant the sum of all lengths the length of the previous segment is modified. | |
|
A3: Constant radius method with compensation of the next segment
The same as method A2, but instead of the previous segment the next one is used for the length compensation. | |
|
A4: Constant radius method with compensation of the previous and next segment
Combination of A2 and A3. How much of the surplus length should be added to the previous segment can be pre-set. The rest is added to the next segment. A4 Track Holding Method: The surplus length is divided automatically to the previous and next segment, that the strip is guided straightaway with constant intersection point of the tangents on the inner or outer side. |
