Abstract
A web system, such as a printing web system, having reduced power consumption is disclosed. Power consumption is reduced by joining the unwind and rewind shafts of the web system together through a continuously variable transmission (CVT). The CVT allows the unwind and rewind rolls to provide torque to each other as well, allowing fewer drive motors and/or drive motors of smaller size to be used in the web system.
Claims20
A web system that provides tension with reduced power consumption, comprising:
- an unwind shaft, a rewind shaft, and a processing system;
- a drive path running from the unwind shaft through the processing system to the rewind shaft;
- a drive motor located along the drive path;
- and
- a continuously variable transmission comprising a first shaft and a second shaft, the first shaft and second shaft being connected to each other through a power transfer linkage;
- wherein the first shaft is connected to the unwind shaft and the second shaft is connected to the rewind shaft.
A web system that provides tension with reduced power consumption, comprising:
- an unwind shaft, a rewind shaft, and a processing system;
- a drive path running from the unwind shaft through the processing system to the rewind shaft;
- a drive motor located along the drive path;
- a tension measurement system located along the drive path;
- and
- a continuously variable transmission comprising a first shaft and a second shaft, the first shaft and second shaft being connected to each other through a power transfer linkage;
- wherein the first shaft is connected to the unwind shaft and the second shaft is connected to the rewind shaft.
A method of reducing the power consumption of a web system, comprising:
- providing a web system comprising an unwind shaft, a rewind shaft, and a processing system;
- and
- connecting the unwind shaft and the rewind shaft to a first shaft and a second shaft of a continuously variable transmission.
