 +===== Kneading Elements =====
 +
 +While defining **Kneading blocks** a few aspects are to be considered:
 +  * In order to define kneading blocks completely, the **Number of discs** of one kneading block is to determine in addition to **Length** and **Diameter**.
 +  * Furthermore, the **Staggering angle** has to be entered. The staggering angle is only permitted in the range of
 +
 +$$-\frac{180°}{z} \leq \text{Staggering angle} \leq \frac{180°}{z}$$
 +
 +with i as **Number of flights** of the element. A negative angle identifies a reconveying kneading block, in contrast positive angle characterizes a conveying kneading block. Neutral kneading blocks are indicated by a Staggering angle of 180°/i.

 +**Shouldered kneading blocks** possess smaller kneading discs than standard kneading blocks. That is why a bigger leakage gap comes into existence. SIGMA makes the assumption that the width of the shouldered kneading block discs is half the width of the standard kneading block discs. Hereby the input mask is the same as for standard kneading blocks.
