  • Please imagine how you manufacture both.

    It is not easy to turn two types of rollers with barrel shape.

    Actually, the number of the parts decreased into approx one-third.

  • Seems that it's more complicated than the compared mechanism.

    why is it worthy?

  • It's extremely cool!

    The actuated rollers with sliding surfaces are quite innovative.

  • @ysuga0731 Thanks!
