While defining Transition kneading elements 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 for the discs. The staggering angle is only permitted in the range of

$$-\frac{180°}{i} \leq \text{Versatzwinkel} \leq \frac{180°}{i}$$

with i as Number of flights of the element. 2-3 describes a transition element with double-flighted to triple-flighted construction, and 3-2 vice versa. 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. The transition angle alpha' describes the staggering of the last disc.
