Abstract
The parent patent described a bending machine for mfg. truncated cones from metal sheet. A planetary gear system is now useful for driving the transport rolls moving the metal sheet through the bending machine, and in the present invention pairs of planetary gears are employed to transmit a rotational speed from one roll to the next roll to match the path length of the metal sheet in contact with each roll. Internal gear teeth are pref. mounted on each end of each roll and a plain- or ball- bearing located between the two sets of teeth. The planetary gears are pref. located in a longitudinal groove on the transport roll shaft. Ensures that even thick metal sheet or plate is carried through the machine, i.e. the speeds of the rolls match the varying circumference of the cone being formed.
