Abstract
Methods and systems to drive rotary presses are described. In one described example, a rotary press system includes a first rotary press and a second rotary press adjacent to the first rotary press. The first and the second rotary presses are to receive a strip of material. A drive member is operatively coupled to the first and the second rotary presses and a motor coupled to the drive member rotates the drive member to cause the first and second rotary presses to process the strip material.
Claims22
A method of processing a moving material, the method comprising:
- moving a material through a first rotary press and a second rotary press spaced from the first rotary press;
- driving the first and second rotary presses via a first drive gear directly coupled to a first shaft extending from a housing of a motor;
- directly intermeshing the first drive gear with a first gear of the first rotary press and a second gear of the second rotary press;
- coupling a second drive gear to the first drive gear via a second shaft, the second drive gear being intermeshed with a third gear of the first rotary press and a fourth gear of the second rotary press, the first and second drive gears to provide a substantially equal amount of torque to the first, second, third and fourth gears;
- and
- controlling the first drive gear to cause the first rotary press to contact the material at a first position during a first time interval and the second rotary press to contact the material at a second position during a second time interval, wherein the first and second time intervals define a cycle of the first and second rotary presses.

A rotary press system comprising:
- a first rotary press and a second rotary press spaced from the first rotary press to process a material;
- a drive gear directly coupled to a shaft extending from a housing of a motor so that the drive gear and the shaft of the motor rotate at equivalent speeds, the drive gear being intermeshed with a first gear of the first rotary press and with a second gear of the second rotary press to drive the first and second rotary presses;
- and
- a controller operatively coupled to the motor to cause the drive gear to at least one of accelerate or decelerate the first and second gears of the first and second rotary presses to cause the first rotary press to contact the material at a first position during a first time interval and the second rotary press to contact the material at a second position during a second time interval, wherein the first and second time intervals define a cycle of the first and second rotary presses, wherein a speed of the first and second rotary presses substantially matches a speed of the material when the first and second rotary presses are at the respective first and second positions.

- and
- a controller operatively coupled to the motor to cause the first drive gear to at least one of accelerate or decelerate the first and second gears of the first and second rotary presses to cause the first rotary press to contact the material at a first position during a first time interval and the second rotary press to contact the material at a second position during a second time interval, wherein the first and second time intervals define a cycle of the first and second rotary presses.
