Kinematics analysis of threeroll skew rolled hollow shafts. Spiral advance is the most obvious motion feature of the threeroll skew rolled shaft. With the equal pitch spiral advance of the straight shaft section and the variable pitch spiral feed of the variable diameter section, the rolled piece rotates and advances until the end of the rolling process.

Feed angles on the rolls were between 8° and 16° determined by Zhao et al. in 2014. Through the experiment, Pater et al. found 3roll mills were 30% faster than 2roll mills to produce thick tubes as the circumferential flow is increased in 2roll mills at the surface layer, consuming more time and affecting both strains and energy consumption.

The roll mill is a series of long, round rollers pressed tightly against one another. The rollers spin in different directions, the center in opposition to the outside rollers. Each consecutive roller spins faster than the last. This accomplishes two things—1. the faster spinning roller "grabs" the chocolate off of the previous roller 2.
