Movex 553 FLEXTOP - Page 23

Divider - Merger - Sorter - Example
If the spheres are touching a
static support (strips or plate)
their speed will result double than
the speed of the FlexTop belt.
That’s why the FlexTop belt
speed (S
b
) results half of the
goods speed (S
g
).

If the next good is running over
the directional belt before the
first one is already out, it will
start rotating and then the final
position won’t be as programmed.

are suitable: maximum weight
15N per sphere and minimum 6
